增强型智能通信模块
4119A型增强型智能通信模块（EICM）8M811K01 3BSE018173R1
允许Tricon与Modbus主从站，TriStation1131和打印机。
对于Modbus连接，EICM用户可以为一个主机和一个
从设备或RS-485接口主服务器和最多32个从服务器。RS-485
网络中继可以是一个或两个最大双绞线4000英尺（1200米）。
每个EICM包含四个串行端口和一个可操作的并行端口
同时每个串行端口可以配置为Modbus主机，最多
至每个Tricon七个Modbus主机底盘。单Tricon系统
最多支持两个EICM，
必须位于一个逻辑插槽中。
（热备盘功能不可用对于EICM，尽管您可以替换
8M811K01信号处理模块
控制器运行时，EICM出现故障
在线。）每个串行端口都是唯一的
解决并支持
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.
