Methods for I/O control
5.1
MODBUS/TCP
CIE-H12 supports Modbus/TCP. By using this protocol, it remotely monitors and controls
I/O devices. To use this method, your application should support this protocol.
5.1.1 Related Parameters
Parameters
Descriptions
Modbus/TCP
Using Modbus/TCP for controlling I/O ports of CIE-H12.
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-H12 performs active connections
Peer Port
Peer’s local port when CIE-H12 performs active connections
Local Port
CIE-H12’s local port when CIE-H12 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. (Upper version 1.5A)
Macro
Applying macro function on the output port
Initial State
Output port value when CIE-H12 boots up.
