6.2 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
