I'm confused with the version of Modbus instruction. I am using: Modbus RTU module (CM1241) Firmware version 2.2 In Modbus communication of PLC, there are available two Modbus as the figure below. I think that I should choose modbus version V2.1 and V2.2. Am I right? Please help me, I really appreciate your help. Attachment Version 2.2.PNG (102 Downloads)
