Communication channel status A: EWM MFS -PLC Emulator

[former_member452625]

Hi Experts,

We build the connection of SAP EWM MFS -> ABAP PUSH CHANNEL -> PLC emulator. And create the relevant communication channel, and the channel could be started and send telegram ( Type SYES) to PLC and also got the acknowledgement telegram from PLC successfully..

the status of communication channel was 'A' (Synchronization in progress) once the channel started, but will not be updated to 'B' ( 'Synchronization completed successfully') as what I expected.

Hi

Sorry for late response.

Nothing received in EWM mean? do u mean telegram couldn't received in EWM?

please check the incoming telegram bugger in Monitor, if you received any SYEN in failed status there?

Hi

As you mentioned the PLC sent telegram 'SYES' to EWM MFS, which simply means connection with PLC has been established. EWM will respond back by sending the acknowledgement of SYES telegram.

If PLC has some buffered message, then it will will be given the opportunity to clear it’s buffered messages first. PLC has to send Telegram 'SYBE' followed by all buffered message.

Else PLC has to send telegram 'SYEN' to MFS, which as a result will update the Status communication channel to B ('Synchronization completed successfully').

Thanks

hello Ashwani,

The telegram 'SYES' is send from EWM to PLC emulator, and to change status of Communication channel to 'B' , PLC must send telegram 'SYEN' , when i sent this telegram from PLC nothing is received in EWM.so how EWM receive telegrams?

Thank you
