Hi,
I test this also today, with RG V9 and ModBus Poll V. 9.6.0
I get always "Read error" and "Write error" at ModBus Poll.
Maybe someone can support screenshots of settings at ModBus Poll and also ModBus Screen at iPendant?
When the connection is running, is the "Slave status" Running or Idle at ModBus TCP Screen at RG?
Many thanks.
