1. For pre-Ver. 1.2 Units, 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 or Serial Communications Units. A host computer program previ-
ously used for C-series Host Link Units may not function correctly if it is
used in CS/CJ-series PLCs. When using Serial Communications
Boards/Units with Unit Ver. 1.2 or later, these programs can be reused by
setting the Host Link compatible device mode to mode C (C500/120) or
mode D (D200H). (Alternatively, check the host computer program before
using it and make any corrections required to handle different frame text
lengths. Refer to the CS/CJ-series Communications Commands Refer-
ence Manual (W342) for details.)
2. For CS-series PLCs, a high-speed NT Link is available only with Serial
Communications Boards/Units manufactured on or after December 20,
1999. With earlier models, only the standard NT Link is available.
