ServersCheck Modbus RTU (Slave) Add-On
This module connects to the Sensor Gateway (base unit) like any regular sensor. It gathers the data from all connected sensors and then transmits it over RS-485 to a Modbus RTU master control system. The add-on acts as a Modbus RTU slave device and can be daisy chained with other 3rd party sensors (on the IN terminal block). From the OUT terminal block it goes into the ICS system. The Sensor Gateway can transmit data over the IP network (SNMP/Modbus TCP/XML/JSON) and at the same time make the sensor data available to an industrial control system.
