Additional Information
You can send acyclic messages to OMRON slaves by setting the command code to 28 01.
In this case, set the response monitoring time to at least the value set for the message monitor-
ing timer (default: 2s). If it is set to less than the value, communications may be busy even if the
next command is executed after the first one times out.
