received.
A line error has occurred. Check the line.
B111
Transient data receiving order
error
A line error has occurred. Check the line.
B112 Transient data length error A line error has occurred. Check the line.

initialize procedure registration was turned
off before all procedures were completed.
Do not turn the specification of the
remote device station initialize
procedure registration off until all
procedures are completed.
B124
Error at a station on which the
remote device station initialize
procedure registration function
was executed The specification of the remote device
station initialize procedure registration
