"Modbus AC450" resolves the following:
- Modbus AC450
I've got a problem with my Modbus interface (Siemens - ABB AC450). INSTALLATION AC450 CI532V02 - Westermo modems - Siemens All wiring was checked and is according to manual PROBLEM If we start the modbus with the service terminal on the MVIxx element (ABB is the slave) I get the following system message: MTypeCodeAddressData1Data22956H'00070014H'00060000H'000000012962H'00000002and the link does not start up.
The system message I get is not explained in the manual. The ABB system is a repetition from a previous unit and the set-up is the same. I get as far as seeing it is a illegal line characteristics parameter but I don,t know which one. Can the master system be setup wrongly to give me this error.
