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

4.2.6. Inserting Unicode Strings into a Message

iKAN display devices provide Modbus registers for 1 Unicode strings, allowing the Host PC or a
PLC to read or write data via the Modbus TCP/ RTU protocol. The Unicode string is up to 32
characters (32 Modbus registers with 1 Unicode character in each). The string can be displayed in
a similar way to display variables. If the string is 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
%
One Unicode strings can be stored on the iKAN series device, and can be accessed using Modbus
register addresses 43000 to 43031.
Modbus Address
Length
Decimal Hex.
43000 0BBB
: :
43031 0BD7
The color of each character in the Unicode string can be set individually, but the color will use up
one Modbus register space. If the total length of the Unicode string is less than 32 characters, fill
in 0 at the end address of the string as an end character.
