Methods for I/O control
5.1
Modbus/TCP
CIE-H14 supports Modbus/TCP. By using this protocol, it remotely monitors and controls
I/O devices. To use this method, users’ application should support this protocol.

parameter
description
Modbus/TCP
Using Modbus/TCP for controlling I/O ports of CIE-H14.
Slave
The slave responses by queries from the Master
Master
The Master sends queries to the slaves
Poll Interval
the period for sending queries (Unit: ms, Minimum value: 10)
Unit ID
ID for identifying the device or the pair of devices.
Input Port Base
Address
Initial address of the input ports
Output Port Base
Address
Initial address of the output ports
Passive Connection waiting for accepting a Modbus/TCP connection
Active Connection
requesting a Modbus/TCP connection
Multiple Connection The numbers for multiple Modbus/TCP connections.
Control Method of
(FC XX)
Control method for the output ports of the slave (Single /
Multiple)
Control Method of
(AND/OR)
Control method for the output ports of the master (AND / OR)
Peer Address
Peer’s IP address when CIE-H14 performs active connections
Peer Port (Active)
Peer’s local port when CIE-H14 performs active connections
Local Port (Passive) CIE-H14’s local port when the CIE-H14 performs passive mode.
Input Change
Notification
A function for immediate notification with changing the IP
address.
Initialize the output
port state
The Output port will be changed to the [Initial State] when
Modbus/TCP is disconnected.
Macro
Applying macro function on the output port
Initial State
