Communication ID setting
By use of rotary switch SW2 on top of equipment
Using the switch SW2 on the top of the equipment, set a communication ID (1 – 9) for each
piece of the equipment. When setting an ID, ensure that IDs do not overlap among the
equipment and are unique ones.
With the user system such as a PC and PLC as the master and this equipment as the slave,
sending a command message from the master begins communications and returning a
response message from the slave ends communications. Since the master and each slave
share the message send/receive path, follow this procedure to ensure that messages do not
collide.
