Note:
•
The method for writing text segments in the message varies depending on the type of command.
•
If there is a large number of characters to be written, they may be divided and sent as several
commands. If there is a large number of characters in the value that was loaded, they may be divided
and several responses sent.
Key Point:
•
With the FP
Σ
, an expansion header “<” is supported to send single frames of up to 2048 characters as
well as general “%”.
Type of header
No. of characters that can be sent in 1 frame
%
Max. 118 characters
<
Max. 2048 characters
Response message
The PLC that received the command in the example above sends the processing results to the computer.
1. Header (start code)
A “%” (ASCII code: H25) or “<” (ASCII code: H3C) must be at the beginning of a message. The response
must start with the same header that was at the beginning of the command.
2. Unit number
The unit number of the PLC that processed the command is stored here.
3. Text
The content of this varies depending on the type of command. The value should be read based on the
content. If the processing is not completed successfully, an error code will be stored here, so that the
content of the error can be checked.
