Product Introduction
The Model 4119A Enhanced Intelligent Communication Module (EICM) allows the Tricon to communicate with Modbus masters and slaves, TriStation 1131, and printers.
For Modbus connections, the EICM user can select the RS-232 point-to point interface for one master and one slave, or the RS-485 interface for one master 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).

Product Details
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 uniquely addressed and supports either the Modbus or TriStation interface.

(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 uniquely addressed and supports either the Modbus or TriStation interface.
Modbus communication can be performed in either RTU or ASCII mode. The parallel port provides a Centronics interface to a printer.
Each EICM supports an aggregate data rate of 57.6 kilobits per second (for all four serial ports).
Programs for the Tricon use variable names as identifiers but Modbus devices use numeric addresses called aliases. Therefore an alias must be assigned to each Tricon variable name that will be read by or written to a Modbus device. An alias is a five-digit number which represents the Modbus message type and the address of the variable in the Tricon. An alias number is assigned in TriStation 1131.
