â– Outputting to Data Registers (DR) for MAX(182) or MIN(183)
If MAX(182) or MIN(183) is executed with a data register specified as the out-
put word for the minimum or maximum value, an instruction execution error
will occur and the ER Flag will turn ON.

Enabled Flags
A20200 to
A20207
Turns ON when a network instruction (SEND, RECV,
CMND, or PMCR) can be executed with the corre-
sponding port number or background execution can be
executed with the corresponding port number (CS1-H,
CJ1-H, or CJ1M CPU Units only). Bits 00 to 07 corre-
spond to communications ports 0 to 7
When the simple backup operation is used to performed
a write or compare operation for a Memory Card on a
CS1-H, CJ1-H, or CJ1M CPU Unit, a communications
port will be automatically allocated, and the correspond-
ing flag will be turned ON during the operation and
turned OFF when the operation has been completed.

Error Flags
A21900 to
A21907
Turns ON when an error occurred during execution of a
network instruction (SEND, RECV, CMND, or PMCR).
Bits 00 to 07 correspond to communications ports 0 to
7.
When the simple backup operation is used to performed
a write or compare operation for a Memory Card on a
CS1-H, CJ1-H, or CJ1M CPU Unit, a communications
port will be automatically allocated. The corresponding
flag will be turned ON if an error occurs and will be
turned OFF if the simple backup operation ends nor-
mally.

Completion
Codes
A203 to
A210
These words contain the completion codes for the cor-
responding port numbers when network instructions
(SEND, RECV, CMND, or PMCR) have been executed.
The contents will be cleared when background execu-
tion has been completed (for CS1-H, CJ1-H, or CJ1M
CPU Unit only). Words A203 to A210 correspond to
communications ports 0 to 7.
When the simple backup operation is used to performed
a write or compare operation for a Memory Card on a
CS1-H, CJ1-H, or CJ1M CPU Unit, a communications
port will be automatically allocated, and a completion
code will be stored in the corresponding word.
