Modbus TCP PLC App with Codesys

[GBARyder]

For supporting MODBUS-TCP, the suggestion was to use the PLC App with CODESYS - Fieldbus communication Add-on, but I did not find one item for Modbus support in the configuration tool.

Is any documentation available to describe this functionality?

Hi GBARyder,

maybe this was a missunderstanding.

Modbus-TCP is not a Codesys Addon, you can use directly in PLC Engineering our library CXA_ModbusTCP.

Dear All,

Customer want to use our CtrlX Core (Modbus TCp IP protocol) connect to BACnet IP via Intesis gateway as link:

https://www.intesis.com/products/protocol-translator/bacnet-gateways/bacnet-client-modbus-server-ibo...

Do anyone have experience about this gateway.

Do we need any recheck, @TheCodeCaptain, @CodeShepherd please help

And they ask:

1. . How many server does a Ctrl X Core (client) can connect to
2. . How many register could CtrlX Core read in once times

As I check here, there is no limit information:

Thank you so much

Hello,

I don't know the answers to the questions asked, but I also have an alternative solution. Our XM2 and XM4 controllers support BACnet IP as client and server. A connection between the ctrtlX core and the XM controllers would then also be possible via OPC UA. This could be more powerful than a Modbus/TCP connection.
