增強(qiáng)型智能通信模塊
4119A型增強(qiáng)型智能通信模塊（EICM）8M811K01 3BSE018173R1
允許Tricon與Modbus主從站，TriStation1131和打印機(jī)。
對于Modbus連接，EICM用戶可以為一個主機(jī)和一個
從設(shè)備或RS-485接口主服務(wù)器和最多32個從服務(wù)器。RS-485
網(wǎng)絡(luò)中繼可以是一個或兩個最大雙絞線4000英尺（1200米）。
每個EICM包含四個串行端口和一個可操作的并行端口
同時每個串行端口可以配置為Modbus主機(jī)，最多
至每個Tricon七個Modbus主機(jī)底盤。單Tricon系統(tǒng)
最多支持兩個EICM，
必須位于一個邏輯插槽中。
（熱備盤功能不可用對于EICM，盡管您可以替換
8M811K01信號處理模塊
控制器運(yùn)行時，EICM出現(xiàn)故障
在線。）每個串行端口都是唯一的
解決并支持
Modbus或TriStation接口。
Enhanced Intelligent
Communication Module
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).
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.
