Inserting Ascii Strings Into A Message - ICP DAS USA iKAN Series User Manual

4.2.5. 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. Each ASCII string is up to 64 characters (32
Modbus registers with 2 ASCII characters in each). These strings can be displayed in a similar way
to display variables. If these strings are modified via a remote Host or a PLC, the text will be
automatically refreshed when it is displayed on the iKAN series device.
The format for using a variable in a message is a 3-byte string as follows:
1
Delimiter Character
%
A maximum of 8 ASCII strings can be stored on the iKAN series device, and are accessed using
Modbus register addresses 41800 to 42055.
