Inserting ASCII Strings into a Message
iKAN display devices provide Modbus registers for 8 ASCII strings, 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 inserted 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
%
a: ASCII string

A maximum of 8 ASCII strings can be stored on the iKAN series device, and are accessed using
Modbus register addresses 41800 to 41927.
