| The TISOFT CVUTA.DEV driver is incompatible
with Citect TIWAY protocol driver. You must remove this driver from
the CONFIG.SYS file before running Citect with this driver. The
TISOFT CVUTA.DEV driver is used by TISOFT to communicate to the PLC
via the TIWAY card. If this driver is installed, you will get the
error "Unit offline, cannot talk" hardware at random times. The PLC
will go offline and then online again - generating this hardware
error. It may also get into a state where the I/O Device will
remain offline and all communication will be lost. |
