UC-Ethernet module with 16 digital outputs, web interface (Modbus TCP-compatible)
Price range: € 362,95 through € 379,61 Incl. 19% VAT plus shipping
Our promise to you
Our UC-ETH modules are stand-alone modules with a 10/100 Mbit Ethernet interface.
The UC-ETH-R16 module is available with either 16 MOSFET outputs or 16 relay outputs with a switching capacity of up to 3 A.
The module offers the following access options via Ethernet:
- Control via the DEDITEC driver library (DELIB): Based on the DEDITEC Ethernet protocol, it enables simple and uniform integration into a wide variety of applications. In addition, this type of control offers the option of tap-proof, encrypted communication.
- Control via Modbus TCP: This variant allows flexible integration into existing automation and control systems.
- WEB interface: Direct access via the browser for user-friendly operation.
- Ethernet 10/100 Mbit
- Encrypted Ethernet communication
- Open standard or Modbus TCP protocol
- Connection via WiFi possible
- WPS-Funktion
- Webinterface
- 16 digital outputs/MOSFET P-Ch.: up to 48V / 3A
- Timer function
- Timeout protection shutdown
- LED status indicator for each output channel
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.
Changing the parameters in the ICT-Tool
1. Setting/changing the IP address:
The IP address for Modbus TCP and TCP-IP is always identical.
Detailed instructions on how to change the IP address can be found at the following link:
2. Deactivate the Modbus function in the module:
If you want to deactivate the Modbus function, navigate to the “Modbus TCP” submenu, uncheck the “Enable” box, and then save your settings.
3. Port configuration
Modbus TCP communication takes place on port 502 by default. Alternatively, any port between 100 and 49151 can be set.
Modbus I/O test
In the diagnostics section of the ICT-Tool, you can test the module's digital and analog inputs and outputs directly via Modbus TCP. Register addresses as well as transfer and return values are displayed in a debug panel, allowing you to quickly diagnose problems with the D/A converter, for example. A complete overview of all register addresses and examples can be found in the Modbus manual at the following link:
