Mitsubishi Computer Link Master Protocol Sequences
The Mitsubishi Computer Link Master Protocol provides the following 19 communications sequences.
Structure of the Protocol
The following table shows the structure of the Mitsubishi Computer Link Master (A-compatible 1C frame, model
1) Protocol.
• Sending User-specified Commands
Sequence Communications
No. sequence name
800 (0320) Send/receive user-
specified Com-
puter Link com-
mands with ASCII
conversion
801 (0321) Send/receive user-
specified Com-

Computer Link
command
User-specified Converts the text data of a user-specified Computer Link command
into ASCII and sends to the Mitsubishi Computer Link Module with
the specified station number (and the PLC number that follows).
The response data is converted into hexadecimal and stored in the
CS/CJ-series CPU Unit starting from the specified word.
User-specified Sends the text data of a user-specified Computer Link command to
the Mitsubishi Computer Link Module with the specified station
number (and the PLC number that follows) without converting into
ASCII. The response data is stored in the CS/CJ-series CPU Unit
starting from the specified word without converting into hexadeci-
mal.

Reads the word data for the number of device
points starting from the specified device address
for the specified device type (except T, C) in the
Mitsubishi Computer Link Module with the speci-
fied station number (and the PLC number that
follows), converts the data into hexadecimal, and
stores it starting from the specified word + 2 in
the CS/CJ-series CPU Unit.
Reads the word (PV) data for the number of
device points starting from the specified device
address for the specified device type (T, C) in the
Mitsubishi Computer Link Module with the speci-
fied station number (and the PLC number that
follows), converts the data into hexadecimal, and
stores it starting from the specified word + 2 in
the CS/CJ-series CPU Unit.
Writes the word data starting from the specified
word + 6 in the CS/CJ-series CPU Unit to the
number of device points starting from the speci-
fied device address for the specified device type
(except T, C) in the Mitsubishi Computer Link
Module with the specified station number (and
the PLC number that follows).
Writes the word (PV) data starting from the
specified word + 6 in the CS/CJ-series CPU Unit
to the number of device points starting from the
specified device address for the specified device
type (T, C) in the Mitsubishi Computer Link Mod-
ule with the specified station number (and the
PLC number that follows).
