Inserting Coil –type Variables into a Message
The iKAN display device provides Modbus registers for 40 coil variables, allowing the Host PC or a
PLC to read or write data via the Modbus TCP/ RTU protocol. These values can also be inserted
into a message. If these values are modified via a remote Host or a PLC, the value will be
automatically refreshed when it is displayed on the iKAN series device.
The format for using a variable in a message is a 5-byte string, as follows:
1
2
3 to 5
Delimiter Character Variable Type
Modbus Address: 3-digit decimal number
%
b: Coil

A maximum of 40 Coil type variables can be stored on the iKAN series device, and are accessed
using Modbus register addresses 00000 to 00039.
