Product Description – Remote Switching IP and Modbus TCP Module

The WEU-RELAIS-8 is a remote switching IP and Modbus TCP module with 8 digital relay outputs for network-based switching of loads, system components and technical devices. The module combines relay outputs with Ethernet, WLAN/WiFi and USB, enabling switching tasks via IP, browser, web interface, app, TCP/IP or Modbus TCP. As an Ethernet relay module and Modbus TCP relay module, the WEU-RELAIS-8 is suitable for industrial automation, building automation, test benches, control cabinet applications and decentralized remote switching tasks.

System Role in IP-Based Switching and Automation Architectures

The WEU-RELAIS-8 acts as a compact network relay module between the control level and connected loads. Via Ethernet or WLAN/WiFi, the module can be integrated into existing IT, automation and building networks. The relay outputs can then be controlled locally or remotely, for example via browser, software, app, TCP/IP communication or Modbus TCP. This makes the remote switching IP module suitable for applications where technical devices, load circuits or switching points need to be operated or automated via network access rather than directly at the control cabinet.

8 Digital Relay Outputs for Low-Voltage Switching Tasks

The 8 digital outputs are implemented as galvanically isolated relay outputs with normally-open (NO) function. They enable switching of control circuits, signals, technical loads or downstream relays and contactors within the permissible low-voltage range. The relay outputs support a maximum switching voltage of 36 V AC/DC, a maximum switching current of 0.5 A AC/DC, a maximum transport current of 1 A AC/DC and a maximum switching power of 10 W. Each output features its own status LED, allowing switching states to be monitored directly on the module.

Ethernet, WLAN/WiFi, USB and Modbus TCP for Flexible Integration

Ethernet 10/100 Mbit/s, WLAN/WiFi and USB 2.0 are available for communication. Via Ethernet, the WEU-RELAIS-8 can be integrated into wired networks; WLAN/WiFi enables wireless connectivity, including WPS functionality. The USB interface provides a direct local connection to a control computer and supports fast plug-and-play commissioning. Through Modbus TCP, TCP/IP, HTTP, UDP and DHCP, the module can be integrated into various network, PLC and automation environments.

Safe Signal Processing with Galvanic Isolation, Timeout Protection and Fail-Safe

The galvanically isolated relay outputs separate control and load circuits, supporting robust operation in technical environments. Additionally, the WEU-RELAIS-8 features a software-configurable timeout protection function. In case of communication interruptions, defined output states can be applied to prevent relay outputs from remaining in an uncontrolled or undesired state. The fail-safe mode further increases operational safety by allowing the module to switch to predefined safe states when a connection is lost.

Event Control and M2M Functionality

The configurable event control enables simple event-based switching and automation sequences directly within the module. This allows defined conditions to be linked to switching actions without requiring a higher-level PC application to trigger every task. Additionally, the M2M functionality supports use in networked automation environments where modules, controllers or software components communicate with each other and execute switching operations automatically.

Access times tests

This test can be used to determine the access times to the module. The test values are read and written in 8, 16, 32, or 64-bit commands.

Access times Register
The following example checks the register accesses to an Ethernet module. The average access time here is 0.5 ms.

Access times Analog I/O
In the following example, the access times to an Ethernet module with analog I/Os are checked. The average access time here is 0.6 ms.

Access times Digital I/O
In the following example, the access times to an Ethernet module with digital I/Os are checked. The average access time here is 0.6 ms.


Cable feedback tests
For this test, the digital or analog outputs of the module are connected to the corresponding digital or analog inputs of the module via cable. The feedback test now checks whether the output and input values match.

Cable return test

The cable return test can be used to check the function of all digital and analog inputs and outputs (I/Os) of a module. To do this, inputs and outputs are wired together externally on a 1:1 basis. The test software analyzes whether the output signals arrive correctly at the inputs, thereby identifying wiring errors or hardware defects.

Analog test
In analog test mode, the D/A converter outputs defined test voltages, which are then read in by the A/D converter and compared with the target values. The software counts the number of test runs and automatically documents any deviations.

Digital test
In the digital test, the switching states of the relay or MOSFET outputs are fed back externally to the optocoupler inputs. Here, too, the software counts and compares the number of cycles and automatically detects transmission errors or deviations.

A/D ripple
The ripple test displays the residual ripple of the individual A/D inputs.

A/D quality measurements

The quality of an A/D measurement is influenced by various factors and can be affected by external interference. A reliable method for checking measurement quality is to measure a stable battery voltage. Our diagnostic tools can be used to determine the residual ripple and noise behavior.

A/D ripple
The A/D ripple test can be used to measure the residual ripple of the individual A/D inputs and check for interference signals such as mains hum or voltage instabilities.

A/D noise
The noise behavior of each A/D channel can be displayed graphically using A/D noise measurement. Additional filter stages with averaging can be used to smooth and improve the measurement signal.


FIFO In/Out

The software FIFO test can be used to specifically test the integrated FIFO buffering of our digital and analog NET I/O modules. Depending on whether it is an input or output module, data is read from the submodule FIFO or written to the submodule FIFO.

 

FIFO settings

The submodule number can be used to specify which module is to be tested. The start and end channels can also be used to transmit several channels simultaneously. In addition, the transmission frequency can be set and the desired FIFO mode selected – for example, for the use of test values or the actual measured values of the module.

All important information at a glance

During program execution, key information such as the size of the data packets, free and occupied bytes in the FIFO buffer, the number of data packets sent or received, and the current FIFO status are clearly displayed.


D/A output test

The D/A output test enables targeted testing of each individual D/A channel of a module. A freely selectable test voltage can be output directly. Currently, simple square wave signals with configurable high and low times are available. The signals can be monitored simultaneously with an oscilloscope. This function is also ideal for long-term tests. The test software detects DELIB errors and logs them automatically.

A connection to the router can be established automatically in the WPS tab. To do this, press the “WPS Start” button and activate the WPS function on the router within two minutes. The devices will then connect to each other automatically.

If the router login data is known, a connection can be established in the WiFi configuration tab by entering the user name and password. Please note that WiFi must also be activated.

Control of Ethernet modules via Modbus TCP protocol

Modbus TCP is a protocol based on TCP/IP that is used for communication between different devices. It allows data to be read and written via so-called registers and bits. Standardized function codes are used for this purpose, such as:

General register allocation

Modbus
register
(dez)
Data type Access Data
size
(Bit)
Description
0 ... 9999 Coil write / read 1 Writing and reading back digital outputs
10000 ... 19999 Discrete Inputs read 1 Read digital inputs
30000 ... 39999 Input Register read 16 Read holder register
40000 ... 49999 Holding Register write / read 16 Write and read back registers

Control of Ethernet modules via Modbus TCP

Our modules can be controlled via the Modbus register protocol for quick and easy integration. This protocol allows you to conveniently read and write values, switch digital outputs, or query inputs. The complete protocol is available for download.

Example:

// Writes the digital outputs of channels 1-16
MASTER.WriteMultipleRegisters(SLAVE_ID, 0x0420, 0x03);

// Reads the values from channels 1-16
registerValue = MASTER.ReadHoldingRegisters(SLAVE_ID, 0x0420, NUMREGISTERS);

 


Configuration of our Modbus TCP modules

The Ethernet module is configured as follows at the factory:

Modbus active = YES
Modbus IP address = IP address of the module
Modbus port = 502 (standard Modbus port)

If you would like to use your own settings or deactivate the Modbus function, please use the configuration menu of our ICT-Tool.

General information on Event-Control

In den folgenden Kapitel, würden wir Ihnen unsere neue All-In-One-Software gerne genauer vorstellen.

To make our modules even more customer-friendly and flexible and to make it easier for you to enter the world of automated control technology, we have implemented Event-Control as a new feature in our products. This function can be used to implement small control tasks that are stored in the module. These control tasks are configured as events and actions and then executed automatically according to the “if-then” principle.

Configuration in the ICT-Tool
The ICT-Tool can be used to configure and monitor 16 events and 16 actions.

Processing in the module
The events stored in the module are automatically monitored and processed by the CPU in the module after the module is started. As soon as the set condition (“event”) is fulfilled, the corresponding action is executed. This automatism in the module makes an additional control PC with associated user software superfluous.

Functions
The following actions, among others, can be combined with the Event-Control:

  • Monitoring the analog and digital inputs (A/D, DI)
  • Setting switching thresholds for analog inputs
  • Switching the module outputs (relay, MOSFET, D/A)
  • Sending CAN packages

We are constantly expanding the range of promotional options. We are also happy to implement your special customer requirements on request.

With the Event-Control module, you can react flexibly and automatically to external signals – directly on the I/O module, without a PC or additional controller.

How does it work?
The system registers external events, such as the switching of an input or the triggering of a sensor, and then executes predefined actions. These actions can be simple tasks such as switching on a relay or sending a CAN message.

The advantages:

  • Independent processing – Control takes place directly on the module, independently of the host system.

  • Flexibly customizable – you can link any inputs and outputs together.

  • Complex logic possible – Thanks to logical operators such as AND, OR or NOT, even more sophisticated controls can be implemented.

  • Simple configuration – events and actions are conveniently defined via our ICT-Tool and transferred to the module without any programming knowledge.

Example:
A digital input detects the opening of a door. The system then automatically switches on a light without a PC being involved.

An event is used to execute a specific action as soon as a condition is met.
A time period can also be specified for how long the condition must be fulfilled in order to execute an action.
These settings are saved directly in the Module-Configuration-Memory of the module.
Example: Voltages can be automatically output via the D/A converter or relays can be switched when a previously defined switching threshold is reached at the A/D inputs or a signal is detected at a digital input.

Depending on the features of your product, you can choose from different modes:

“DI” / “DI flip-flop” / “DO readback”
DI: High or low signal of a digital input.
Flip-Flop: If the status of the digital input changes, the flip-flop of the channel is set and then reset again.
DO-Readback: The status of the output channel is read out.

The following settings can be made:

  • Number of the channel to be monitored
  • Condition of the channel status (on = 1 / off = 0)
  • Minimum time to wait until the action is triggered
  • Number of the action to be executed (this is configured in the Action area)

“A/D”
The voltage currently present at the analog input is read out.

The following settings can be made:

  • Number of the channel to be monitored
  • A/D mode (selection depends on module)
  • Condition that must be fulfilled (value greater than … , value less than … , value in a range)
  • Values that must be achieved for the condition
  • Minimum time to wait until the action is triggered
  • Number of the action to be executed (this is configured in the Action area)

In the “Actions” section of our ICT-Tool, you define which tasks are to be performed automatically as soon as a condition (“event”) is fulfilled.
For example, you can specify that a certain CAN packet should be sent when a certain voltage is measured on an A/D channel or a signal is detected at a digital input.

Depending on the features of your product, you can choose from different modes:

Folgende Informationen können der Statistik entnommen werden:

  • Ausgeführte Event-Nr.
  • Event-Modus
  • Intervall
  • Anzahl ausgeführter Events
  • Nummer der ausgeführten Aktion
  • Anzahl ausgeführter Aktionen

“Set D/A output”
Outputs a voltage or a current at an analog output.

The following settings can be made:

  • Number of the channel on which the action is to be executed
  • D/A mode (selection depends on module)
  • Voltage or current to be output
  • Time to wait before executing the action again

“Set DO output”
Switches a digital output on or off.

The following settings can be made:

  • Number of the channel to be controlled
  • State (0 = off / 1 = on) that is to be set
  • Time to wait before executing the action again

“Send CAN package”
The set CAN TX event is triggered. For this function, the trigger mode in the CAN TX package must be set to “TX-EVENT” (see configuration).

The following settings can be made:

  • Number of the CAN TX event to be triggered
  • Time to wait before executing the action again (prevents a CAN packet from being sent too frequently)

You can find more information on configuring TX mode here:

Timeout protection function

Icon Delib Command

DapiSpecialCMDTimeout

This command is used to set the timeout protection function.

Description
This command is used to set the timeout protection function.
There are three different timeout methods since 2021.

"normal" timeout
This is the timeout that our modules have had since 2009.
Procedure for the timeout command:
The timeout is activated by command.
If a so-called timeout event then occurs (pause between two accesses to the module is longer than the permitted timeout time), the following happens:
- All outputs are switched off.
- The timeout status changes to "2".
- The timeout LED goes on (for modules that have such a status)
Further access to the outputs is then still possible, but the timeout is no longer active. Only when it has been reactivated.

"auto reactivate" timeout
This is a timeout mode implemented since 2021, which automatically reactivates the timeout after the timeout event occurs.
Procedure for the timeout command:
The timeout is activated by command.
If a so-called timeout event then occurs (pause between two accesses to the module is greater than the permitted timeout time), the following happens:
- All outputs are switched off.
- The timeout status changes to "4".
- The timeout LED goes on (for modules that have such a status)
Further access to the outputs is then still possible. AND the timeout is still active. If the timeout time is exceeded again, the outputs are switched off again.

"secure outputs" timeout
This is a timeout mode implemented since 2021, which prevents write access to the outputs after the timeout event occurs, thus ensuring that the software must first restore a "secure" state of the outputs, as the module's timeout mechanism has changed the outputs to predefined values.
Procedure for the timeout command:
The timeout is activated by command.
If a so-called timeout event then occurs (pause between two accesses to the module is longer than the permitted timeout time), the following happens:
- All outputs are switched off.
- The timeout status changes to "6".
- The timeout LED goes on (for modules that have such a status)
Further access to the outputs is NOT possible. The outputs can only be written to after the timeout has been reactivated or deactivated.

Definition

Parameter
cmd = DAPI_SPECIAL_TIMEOUT_SET_VALUE_SEC
par1 = seconds [s]
par2 = milliseconds [100ms] (value 6 = 600ms)

Remark
The permissible value range of the time specification is between 0.1 seconds and 6553 seconds

Programming example

DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_TIMEOUT,
DAPI_SPECIAL_TIMEOUT_SET_VALUE_SEC, 3, 7);
//The timeout time is set to 3.7 sec.

DapiSpecialTimeoutActivate

This command activates the "normal" timeout.

Description
This command activates the "normal" timeout.
After the timeout event...
- ...all outputs are switched off
- ...the timeout status is set to "2"
- ...the timeout LED is switched on (for modules that have such a status)
Further access to the outputs is then still possible, but the timeout is no longer active.
Only when it has been reactivated.

//The "normal" timeout is activated.

DapiSpecialTimeoutActivateAutoReactivate

This command activates the "auto reactivate" timeout.

Description
This command activates the "auto reactivate" timeout.
In this mode, the timeout is automatically reactivated after the timeout event.
After the timeout event...
- ...all outputs are switched off
- ..the timeout status is set to "4"
- ...the timeout LED is switched on (for modules that have such a status)
Further access to the outputs is then still possible AND the timeout is still active.

DapiSpecialTimeoutActivateSecureOutputs

This command activates the "secure outputs" timeout.

Description
This command activates the "secure outputs" timeout.
In this mode, write access to the outputs is prevented after a timeout event.
This ensures that the software must first restore a "secure" state of the outputs,

After the timeout event...
- ...all outputs are switched off
- ..the timeout status is set to "6"
- ..the timeout LED is switched on (for modules that have such a status)
