This enables the data in the reception buffer
received in the previous communications sequence
to be held after switching the communications
sequence during full-duplex communications.

Computer Link commands can be used to access a
Mitsubishi PLC (Sequencer CPU Module) slave.
--- Communications sequences with different send
and receive protocols are provided by using send/
receive commands with ASCII conversion.
The communications sequences have been
expanded to include CompoWay/F commands
such as VARIABLE AREA READ/WRITE and
OPERATING INSTRUCTIONS.
Unit version 1.2 or later
Host Link C-mode com-
mands can be used to
access a C-series or CS/
CJ-series PLC slave.
Host Link FINS com-
mands can be used to
access a CS/CJ-series
or CVM1/CV-series PLC
slave.
This protocol can also
be used to access slave
PLCs on the network.
