I'm using a Schneider PCI-85 Modbus Plus card in a Citect (TM) SCADA IO server to communicate to PLCs on a Modbus Plus network. It drops out all the time, and the Citect server is constantly re-starting the Citect driver for most of the devices.
(Not to be confused with the MBX driver; that stays running as far as I'm aware. MBX Demo shows similar drop-out behaviour for the nodes on the network.)
In exactly the same situation, a SA-85 card (which is an older ISA bus card) works with little trouble.
All software appears to be installed correctly.
Has anyone else had similar trouble with these PCI-85 cards?
Thanks in advance,
kind regards,
Roger.
