Data read from Siemens(PLC)

[breckjensen]

Hello everyone,



I have a problem while reading data from Siemens PLC. I'm using Codesys for reading data from other PLC's through Modbus interface, but for Siemens, it's a little bit different.



Maybe there is a possibility to read data with Python from Siemens with PLC and then to read it with Codesys? Maybe someone has tried something like this? Or you have other ideas how to solve this problem?



Please help.

Thanks!

With Codesys, declare the data types to store the parameters, then give them an instance in Global Variables. OPC is also a solution.
(if opc_da, check dcom settings, firewall too. See support.industry.siemens.com/cs/ww/en/view/13542666)
