The controller provides control, data logging, alarming, scheduling, integration.
To allow IP connectivity there are 2 Ethernet ports, which operate as two independent ports. A built-in RS485 port can be used to expand the number of I/Os by connecting the multiprotocol I/O modules (MINI, MIX, or MAX series) or to integrate with other subsystems.
