Communication Setting
The recommended communication parameter setting of both PLC and POD is as follows:
*
For the SYSMAC- Series and COM1 Series, set “0001” into DM6645 and “0304” (HEX) into DD6646 on
the RS-232C port at the CPU side to use the recommended communication settings indicated in the table
above.
For the CS1 Series, store the values which match the communication setting in D32000 (D32010) and the
following when the communication board is used for communication; in the memory space corresponding
to machine No. when the communication unit is used.
•
If [SYSMAC C] is selected at the [Select PLC Type] dialog, set the [Trans. Mode] for [Detail] in the
[Comm. Parameter] in UG00S-CW.
