text: <s>[INST] CompactLogix L43 with PowerFlex 4 on 22-SMC-232 Guys,Anyone knows how to setup CompactLogix DF1 port for serial communication with PowerFlex 4 through 22-SMC-232? Customer is using 22-SMC as RTU Master. The only time when i got any action on the converter module is when CompactLogix DF1 is set as DH485. Just want to make sure i'm on the correct path here...thanks for any help.ReagrdsRobert [/INST] The controller serial port should be configured to use DF1 protocol, as the 22-SCM-232 provides both media (RS232 to RS485) and protocol (DF1 to Modbus RTU) conversions.I suggest to review the 22-SCM-232 User Manual , chapter 3 and 4 for all the settings, App. H for an example about the Powerflex control from ControlLogix / Compactlogix serial port. Hope this helps… - fuzzy logic \\n </s>
