Hi
I am trying to connect a Samba PLC to a SEW MDX61B VSD via Ethernet and using Modbus TCP. Using the function blocks in the Samba program I can get it to connect to the SEW VSD but when I try and read an address which the SEW guys say is correct, 8320 which is the encoder position it shows a status fault code of 7. I can connect the same program to a Jazz PLC and read an address in it.
The Samba is the Master and SEW the slave, can someone help, I think it looks like a case of just the wrong address or maybe an extra number before it
Thanks Phil
