Inserting Integer-Type Variables Into A Message - ICP DAS USA iKAN Series User Manual

4.2.2. Inserting Integer-type Variables into a Message

iKAN display devices provide Modbus registers for 64 integer 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 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
Delimiter
Character
%
A maximum of 64 integer variables can be stored on the iKAN series device, and are accessed
using Modbus register addresses 40000 to 40063.
