Changes from Previous Host Link Systems Appendix B
Note The number of words that can be read and written per frame (i.e., the text lengths) when using C-mode
commands is different for C-series Host Link Units and CS/CJ-series Serial Communications Boards/
Units. A host computer program previously used for C-series Host Link Units may not function correctly if
used for CS/CJ-series PLCs. Check the host computer program before using it and make any correc-
tions required to handle different frame text lengths. Refer to the CS/CJ-series Communications Com-
mands Reference Manual (W342) for details.
CVM1 or CV-
series CPU Units
CVM1/CV-CPU@@-E No changes have been made
in wiring.
It may be possible to use the host computer
programs without alteration as long as the
same communications settings (e.g., baud
rate) are used. It may be necessary, however,
to change programs to allow for different CS/
CJ command specifications.
