Expanded System Configuration
No-protocol
Communications
1:1 Data Link System
Note The link area will always be LR 00 to LR 15 (16 words) for 1:1 Data Link com-
port on the CPU Unit, as well as the RS-232C port and RS-422A/485 port on
the Serial Communications Board.
For details on cables required to connect the host computer to the CQM1H in
Host Link Mode, refer to 3-6 Programming Devices .
The TXD(––) and RXD(––) instructions in the ladder program can be used
with no communications protocol or conversion to transfer data with a general-
purpose external device equipped with an RS-232C port. It is possible to
attach a start code to the beginning and an end code to the end of data (or
specify the amount of data) when sending/receiving. Unlike protocol macro, it
is not possible to construct a communications frame (message) according to
the communications specifications of the communications partner. Also, there
are no procedures for retry processing, data format conversion processing or
branch processing for receiving data. This communications mode is thus used
for simple data transmissions, such as inputting bar code data and outputting
printer data. This mode is supported by the peripheral port and the RS-232C
port on the CPU Unit, as well as the RS-232C port and RS-422A/485 port on
the Serial Communications Board.
If two PCs are linked one-to-one by connecting them together through their
RS-232C ports, they can share up to 64 words of LR area. One of the PCs will
serve as the master and the other as the slave.
One of the following three ranges of words can be set to be linked:
LR 00 to LR 63, LR 00 to LR 31, or LR 00 to LR 15
A 1:1 Data Link communications system can be created between the CQM1H
and another CQM1H, or between the CQM1H and the CQM1, C200HX/HG/
HE, C200HS, CPM1, CPM1A, CPM2A, CPM2C, or SRM1(-V2).
munications with the CPM1, CPM1A, CPM2A, CPM2C, or SRM1(-V2).
