Communication Protocols

The communication protocol of NX-CPU700p PLC provides a complete 
method of communications between the graphic consol programmers 
(WinGPC) and the PLC by controlling programs, CPU status, and I/O at 
user’s convenience. The user can easily expand the capabilities of the 
overall PLC system by communicating to the PLC using a variety of 
peripheral communications equipment in accordance with the 
following communication protocols and procedures. Additionally, the 
communications protocol allows for the PLCs to communicate to a 
central computer on a single network using RS485, at a distance of up 
to 1.2 km (RS232C, 15 m). 

Communication Protocols for NX-CPU700p

 

•

Half duplex asynchronous

•

Parity: No parity

•

Stop bit: 1 stop bit

•

Communication method: RS232 or RS485 (optional)

•

Communication speed: 4800/9600/19200/38400 bps (optional) 

•

Communication cable: refer to the cable wiring diagram

•

Number of PLCs on a single network: Maximum of 64 
(communicating 1:N using RS485) 

•

Maximum communication delay time: 3 seconds
