| The 1799 Modbus emulation card must be set
up with the Modbus Slave Emulation Communications package. This
converts the Modbus messages into the Westinghouse format, and
supports Modbus messages of up to 125 words (250 bytes). The only
Modbus function code not supported by the emulation card is writing
to multiple coils, function 15. If this function is needed, the
MODBUS driver will need modifying to allow a new citect.ini
variable to force writing of multiple coils one bit a time. Contact
Citect Support for more information.
Also, refer to the Westinghouse NCMZ 1799 System Manual Appendix
L for more information on the emulation card.
