Note The user program may need to be altered to enable correct reading of data for
the above difference in frame size. Be sure to check operation and correct the
program as required.

commands
All C-mode
commands
The following C-mode commands are
supported only by built-in Host Links for CPU
Unit of version 2 (-V2) or later and cannot be
used on other CVM1/CV-series Host Links.
RL/WR: LINK AREA READ/WRITE
RH:WH: HOLDING AREA READ/WRITE
CR: DM AREA READ/WRITE
R#/R$/R%: SV READ 1/2/3
W#/W$/W%: SV WRITE1/2/3
Note When the model is changed so that the above commands are no longer sup-
ported, change the user program to perform the same operation using other C-
mode commands or FINS commands.
Communications Port Signals Different communications signals are used for Host Link communications for the
C Series and CVM1/CV Series depending on the model and the type of port. Dif-
ferences in the signals are listed below by port.
RS-232C Port
Signals C-series Host Links CVM1/CV-series Host Links
ST1, ST2, RT Used. Not used.
If the SR1, SR2, and RT signals are not used, the same communications cable
can be used even if the model is changed. If the SR1, SR2, and RT signals are
used, synchronized transfer of data will not be possible if the model is changed.
Change the system to sync on the CD (carrier detected) signal. Part of the cable
wiring must also be changed.
