PLC Networking Applications

These PLCs can be used at different baud rates & different

configurations. For example,
PLC-1=1 start + 7 data + 1 stop=9-bit/byte, baud rate=1200
PLC-n=1 start + 8 data + 1 parity + 1 stop=11-bit/byte, baud rate=9600
PLC-m=1 start + 8 data + 1 parity + 2 stop=12-bit/byte, baud rate=115200

OMRON CQM1

= 1 start + 7 data + 1 even parity + 2 stop =11-bit/byte

OMRON C200 = 1 start + 7 data + 1 even parity + 2 stop = 11-bit/byte

The

7520 can be the 7520 or 7520R, refer to Sec. 2.5 for details.

The

7520R, 7520R, 7520R can be the 7520 or 7520R, refer to

Sec. 2.5 for details. In this configuration, the

PLC1, PLCn, PLCm

provides DC power to

7520R, 7520R, 7520R. This is the cheapest

to the 3000V high isolation. The user should not replace the 7520R,

, ,

, with the 7520.

Refer to “NAP7000S User Manual” for PLC networking software

details.
