Description
Turns ON when a network instruction can be executed
with the corresponding port number or background exe-
cution can be executed with the corresponding port
number. Bits 00 to 07 correspond to communications
ports 0 to 7
Note When the simple backup operation is used to
performed a write or compare operation for a
Memory Card, a communications port will be au-
tomatically allocated, and the corresponding flag
will be turned ON during the operation and turned
OFF when the operation has been completed.
Turns ON when an error occurred during execution of a
network instruction. Bits 00 to 07 correspond to commu-
nications ports 0 to 7.
Note When the simple backup operation is used to
performed a write or compare operation for a
Memory Card, a communications port will be au-
tomatically allocated. The corresponding flag will
be turned ON if an error occurs and will be turned
OFF if the simple backup operation ends normal-
ly.
These words contain the completion codes for the cor-
responding port numbers when network instructions
have been executed. The contents will be cleared when
background execution has been completed. Words
A203 to A210 correspond to communications ports 0 to
7.
Note When the simple backup operation is used to
performed a write or compare operation for a
Memory Card, a communications port will be au-
tomatically allocated, and a completion code will
be stored in the corresponding word.
Turns ON when an instruction execution error or illegal
access error occurs in an instruction being executed in
the background. Turns OFF when power is turned ON
or operation is started.
