Hello sir, I am a new Siemens PLC system user and was tasked with developing a one-off Modbus interface to an external system. Your code does everything I need. I successfully prototyped your Modbus_V6.0 code with a single S7-300 and CP341 (RS485) Modbus RTU Master. When integrating the blocks into our plantwide project, I am encountering errors with the FB50 calls to FB7 and FB8. Our plant logic uses FB7 v2.2 and FB8 v2.7 which appear to have slighly different interfaces and sizes. The itegration seems to be getting tripped up on FB50 pointers to FB7 + FB8. We don't want to downgrade the function blocks to match versions that come with your sample project for fear of adding risk to the other MODBUS RTU interfaces in the plant. Thoughts? ------------------------------------------------------------------------------------------ |
