For almost all models the PLC communication setting method is as follows. However, differences
may arise depending on the model. For details, please consult the manual for the PLC you will
use when making the settings.
To communicate using the RS232C port of the CPU unit
Set the system area as follows.
Address Value set
DM6600 0201 (HEX)
DM6645 0001 (HEX)
DM6646 0004 (HEX)
DM6648 0000 (HEX)
To communicate using the communication port
Set the system area as follows.
To communicate with port A
Address Value set
DM6600 0201 (HEX)
DM6550 0001 (HEX)
DM6551 0004 (HEX)
To communicate with port B
Address Value set
DM6600 0201 (HEX)
DM6555 0001 (HEX)
DM6556 0004 (HEX)
To communicate using the high link I/F unit
Make sure set the CPU mode to monitor mode.
Use the DIP switch or rotary switch on the link I/F unit to make settings such as the baud rate.
For details please refer to the manual for the unit your are using.
To communicate using the peripheral port
Set the system area as follows.
Address Value set
DM6600 0201 (HEX)
DM6550 0001 (HEX)
DM6551 0004 (HEX)
