Ethernet counter module with 8 input counters and 2 output counters
RO-ETH-CNT8
Ethernet counter module with 8 input counters and 2 output counters
- 10/100 Mbit Ethernet interface-controlled input/output module
- 8 input counters (max. 20 MHz frequency)
- 2 ouput counters (max. 5 MHz frequency)
- all in-/outputs have 32bit-counters
- 4 different counter modes:
counting impulses+ counting impulses with "reset when read"/ distance measurement/ number of measurement/
PWM measurement
- galvanically isolated in-/outputs
- LED status indication per input state
This ethernet measurement modules with DIN rail for industrial use is designed to work under industrial environments in switchboards for process measuring and control technology. The modules have a standard 10/100 MBit/sec ethernet interface and are therefore easily connectable to ethernet networks. Ethernet is a worldwide popular standard for LANs and has proven itself.
32 Bit counter with input filter
Every input counter is assiocated with the counter-chip via a optical coupler (max. 20 MHz). Therefore a galvanical isolation is warranted, which allows to connect different voltage levels, but also provides protection for the counter module itself.
Every input counter is provided with a configurable filter. At this juncture, troubles can be filtered at a range of 100 ns to 1 ms .
The counter module has the following 4 modes:
Mode 0: Counting impulses
This mode allows to count impulses based on a rising edge. At this a reset via software is possible.
Mode 1: Counting impulses with "reset when read"
This mode allows to count impulses based on a rising edge. When reading the counter, the counter resets to zero at the same time.
Mode 2: Period determination
In this mode, the period duration "T" of the applied input signal is measured .
An internal 100 MHz counter is used as base period. The 32 Bit counter is placed in a buffer store (Latch), with a rising edge of the input signal, and can be evaluated, while the next signal is counted.
Mode 3: Number of measurement/ Frequency measurement
This mode can measure the number of rising edges of the input signal within a certain time. The mode provides the times 1ms, 10ms, 100ms, 1sec, and can be configurated via software. You could do frequency measurement for example.
Mode 4: PWM measurement
In this mode you can measure, with two different counters, the "high"-time and "low"-time of a signal. With this you can define the high / low-ratio (PWM).
By using an internal 100MHz counter, the PWM - ratio is meticulous.
Peculiarity here is that ANY counter / counter input can be configured separately (filter and counter-mode).
As terminal block, user-friendly terminal strips with locking protection and ejection mechanism are used. They allow quick replugging . The wire connection itself is realised with a screwless connector system. A tool is included with each module.

Ethernet-interface
Configuration over web interface
The ethernet module can be directly connected to a PC. That way, a direct access is given. It may be alternatively connected to a LAN. In case the LAN is accessible over the internet, the module is reachable worldwide.
The configuration of the IP-address is done over the module's web interface, which is easily accessible by a browser.
A provided API library in C allows an easily implement the module access in own programms.
Inputs
Visual monitoring of inputs
The state of every input is directly indicated by a LED. That way, wrong wiring is easily noticeable.
Input protection using optocoupler
The inputs have AC-suitable optocouplers. Therefore you don't need to pay attention to the polarity while wiring the inputs.
Connector
Easy to maintain connector system
The plug and socket consist of a multipoint socket connector and a multipin connector with a throw-off lever. Plug-in and plug-out is easy as well as rewiring the terminal strip. The wire connection itself is realized with a screwless connector system. A tool is included with each module.

Config
Configuring the ethernet interface
Modules with 10/100 Mbit ethernet interface can be connected directly to a PC or to a network LAN.
For configuration you can choose between two options.
1. Configuring using the DELIB Configuration Utility
Here you can change some basic options of the module.
2. Configuring by the internal Web-Browser
Here you can take advanced settings of the module.

If the default IP address of the module is not in the used network range, then the module can not be found over TCP/IP. Availability problems will also appear, if the IP address is already in use. But by using the DELIB Configuration Utility, the netmask and the IP address of the ethernet module can still be configured. Further, the module can directly be connected to the PC and be configured this way. After the accessibility is granted, further configuration is comfortably done by accessing the integrated web server.
Configuration using the module's integrated web-server

The internet module has it's own web-server via which the configuration may be done. Although the IP address and the netmask may be changed this way, much more can be configured than using the DELIB Configuration Utility.

Software
Controlling of our ethernet-modules
Our ethernet modules can be controlled by two different ways.
1. The Windows driver library DELIB
The DELIB driver library allows a direct communication with our modules. You don't have to worry about the TCP/IP protocoll. The driver library assumes it for you!
2. You may program the controlling software by yourself
In our download area you can find the specifications for our TCP-IP protocoll. By this way, our ethernet modules can be connected to small Linux computers or workstations for engineering, with LAN Interface.
Controlling by the DELIB driver library under Windows
The extensive but easy handling library is written for computer language, which responds to DLL's. Programming examples in source code for C, Delphi or Visual Basic can be found in our download area.
Examples for responsing our products with "C"
In the following example we show you in "C", how to access to our input modules in short time.
1. Step: Open the module
handle = DapiOpenModule(RO-ETH,0); //Open Ethernet-module
2. Step: Reading of 16 digital inputs
data = DapiDIGet16(handle, 0); // Read the first 16 digital inputs
3. Step: Close the module
DapiCloseModule(handle); // Close the module
The function "DapiOpenModule" is used to open a special kind of module.
Which module should be openend, is defined by the two parameters.
The first parameter is for the "module ID". By the integrated "DELIB.H", you can also set this parameter to "RO-ETH".
So the driver library recognize, that an ethernet interface will be driven.
The second parameter assigns the module number. If only one module is connected to the pc, the module number is "0". Are there more than one module in the network, you have to set the correct number.
The link to the according IP-address of the module can be configured by the "DELIB-Configuration Utility".

With this program you can test our modules very easily. The digital input/output sample testprogram is easy to use and supports all of our measurement modules. The example above shows the test of a RO-USB-O32 input module.
Controlling by the open source ethernet protocol
If required, you can program your own controlling software. The according communication protocol for TCP/IP is disclosed. The modules will be controlled by register. Therefore we designed an open source communication protocol, which allows to respond to the modules and excecute read/write commands. The manual "Ethernet TCP Protocol" describes transmission and receiving frames, to communicate with our ethernet modules.
