4.2.3.
Inserting float-type Variables into a Message
The iKAN display device provides Modbus registers for 64 float 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
%
f: Float variable (-3.4E+38 to +3.4E+38)

A maximum of 64 float variables can be stored on the iKAN series device, and are accessed using
Modbus register addresses 40000 to 40063.
