FINS Command/Response Format
This section explains the format of the FINS commands and responses spec-
ified by the “
clksend
” library function.
When actually sending or receiving message service data, the contents spec-
ified by the library function parameters are attached as a header. When the
message service is used, however, there is normally no need to pay special
attention to headers.
6-2-1
Headers
Although parameters are used to designate the source, the destination, and
other required information, there are some cases where a header must be
manually added before the command code. Refer to the operation manuals
for individual systems to determine if a header is required. The header format
described below is attached before the command code and the other parame-
ters described for individual commands in the rest of this manual.
