I have a 1515-2pn cpu (v 2.9) and a cm ptp rs422/485 hf (v1.0). I want to read some values on modbus rtu using modbus (rtu) library v4.5. When I add Modbus_comm_ load block it is red and after compiling the software, I get the error: library version conflict for Send_Config v1.2.

What should I do to be able to use modbus (rtu) library v4.5?
