Communication protocols
PROGRAMMING MANUAL 214
Revision 1.0
The Host Link Master protocol supports the commands only in single frame.
The following table shows how you can use the Host Link protocol with the
BASIC commands, and for which CPU unit operating mode (RUN, MON or
PROG) the command is valid.
/i
End codes
These are the end codes defined in the HLM_STATUS parameter:
/i
Note
The Host Link protocol supports only C commands. It does not
support FINS.

Caution
You must execute the Host Link master commands from one pro-
gram task only to avoid any multi-task timing problems.
Caution
The Host Link master commands provide the tools to exchange
data with the Host Link slave. The user program must contain
proper error handling routines to deal with communication failure
and perform retries if necessary.
