Hi Erik
Thanks for your prompt response … … … … .
Listen I’ve been trying get this right for more than a couple of months or so … … … ’ a few days’ or whatever is not a problem. If I run out of patience, I’ll ask the Dr, he’s always got some to spare !
Yes, I know about the Modbus protocol and the configuration and your link will help me get a better handle on that too … … …
Many thanks and enjoy your Christmas … … … … .
