Most SIXNET stations can receive Modbus protocol over Ethernet TCP/IP. This support is based on the Modicon Open Modbus/TCP Specification.
SIXNET stations with Modbus/TCP capability include:
EtherTRAK modules and Ethernet gateways manufactured after November 1999
All IPm stations
SixTRAK programmable Ethernet gateways and VersaTRAK RTUs with gateway / RTU firmware version 2.16 and newer
The ET-GT-ST-# Ethernet I/O Concentrators
IPm stations with version 1.5 or newer firmware can be configured to send Modbus/UDP or Modbus/TCP protocol over their Ethernet port(s) to Modbus compatible devices. This capability requires the optional SCS Feature Set of the SIXNET I/O Tool Kit.
