Hi everybody! I want to connect a CPU 314 with a cp341 ( 6es7 341-1ch02-0ae0) and use the protocol Modbus RTU (Modbus Master) by rs-485 , When i try to send data, the instruction (P_SND_RK) in the STATUS PART shows me the fault 16#F05 and in the diagnostic HW / module information/ Diagnostic Buffer/ there is an alarm and it say " IF1: There is no insert dongle. Do i need the dongle if i want to use the protocol Modbus RTU? what's the part number of the dongle that i have to use? ------------------------------------------------------------------------------------------ |
