Enhanced Intelligent Communication Modules (EICM)support RS-232, RS-422 and RS485 serial communication with Modbus devices and TriStation 1131.For Modbus connections, the EICM user can select the RS-232 point-topoint interface for one master and one slave, or the RS-485 interface for onemaster and up to 32 slaves. The RS-485 network trunk can be one or two twisted-pair wires up to a maximum of 4,000 feet (1,200 meters).Each EICM contains four serial ports and one parallel port which can operate concurrently. Each serial port can be configured as a Modbus master with up to seven Modbus masters per Tricon chassis. A single Tricon system supports a maximum of two EICMs, which must reside in one logical slot.(The hot-spare feature is not available for the EICM, though you can replace a faulty EICM while the controller is online.) Each serial port is uniquelyaddressed and supports either the Modbus or TriSt
