Hey Everybody

I have to communicate a movicon SCADA with TWIDO PLC Through MODBUS Serial. can i address the inputs and the outputs of the twido directly from MOVICON witout moving I/O status to Internal Bits? If its Possible Please Someone Help me out.
 
Hi,

i do not know the movicon SCADA but with other SCADA-s you can communicate only trough the %M and %MW.

Best Regards!

Hello,

You can communicate twido with movicon. Go through the documentation given in movicon in communication section and later on configure you twido plc in twido suite and make sure that your plc is a slave. Also in the ladder program there must be a rung with a short and an operation block with a dummy %MW assigned to any number. This, I think is something weird as the contents of the program must not interfere with the communication with scada. But without this rung movicon was popping an error. Also you can only access MW and M types only.
Someone please correct me if i am wrong.
