Note) The baud rates of 300, 600 and 1200 bps can be specified by the SYS1 instruction. However, the
setting value of the system register cannot be changed.
Programming of computer link
- For a computer link, a program should be created that allows command messages to be sent and
response messages to be received on the computer side. No communication program is required on
the PLC side. (Specify the communication format only by the system register.)
- The program for the computer side must be written in BASIC or C language according to the
MEWTOCOL-COM. MEWTOCOL-COM contains the commands used to monitor and control PLC
operation.
