Using the Modbus Ports

Two-Wire Cabling Schemes for Modbus RS485 Networks, Continued

Cable

All devices are connected with the same pin-for-pin cable, such as the Modbus

 

Plus or Modbus RS485 Short Interconnect Cable or any Cat. 5 4-Twisted Pair

 

Ethernet cable AWG#24. A master/slave system using 2-wire cabling does not

 

require the special master communication cable.
