If function code 4 is required then append (4) to the Register value including the (). Using Function Codesīy default, FabGuard uses function code 3 to poll data. In the recipe, create a tool bin manually and set the Connection to TCP and the Type to Modbus/TCP, Figure 3. In addition to the IP address, the absolute register address is needed.

Then edit the TCP protocol to add/remove the device IP address and TCP port (502), Figure 1.įigure 3: Manual Tool Bin configuration inside of a FabGuard recipe.įabGuard recipes can be set to collect data from the devices as tool bins. Modbus Connection in FabGuard IPMįrom the Tool screen select Configuration > Connections(Sensors and tool) and Add TCP protocol under gauges list. Modbus TCP is supported in FabGuard versions 8.5.6-a and higher. Some devices allow user modification of the base address which then needs to be added to the input register address.įabGuard provides Signal Bins in the recipe with built-in methods to convert Modbus register values into human readable data as explained in the setup. To read the input register value, FabGuard needs the absolute address of the input register.

The most commonly used TCP port for Modbus is 502. Modbus TCP is Modbus protocol wrapped in a TCP/IP layer. Integrating Modbus TCP into FabGuard allows factories to integrate, analyze, and control factory data from external devices such as bath concentration monitors.
