Name Address Description Access
Communications Port Enabled
Flags
A20200 to
A20207
ON when a network instruction (SEND, RECV, CMND, or
PMCR) can be executed with the corresponding port num-
ber or background execution can be executed with the corre-
sponding port number (CS1-H CPU Units only). 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
CPU Unit, a communications port will be automatically allo-
cated, and the corresponding flag will be turned ON during
the operation and turned OFF when the operation has been
completed.

Communications Port Com-
pletion Codes
A203 to
A210
These words contain the completion codes for the corre-
sponding port numbers when network instructions (SEND,
RECV, CMND, or PMCR) have been executed. The contents
will be cleared when background execution has been com-
pleted (for CS1-H CPU Unit only). Words A203 to A210 cor-
respond 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
CPU Unit, a communications port will be automatically allo-
cated, and a completion code will be stored in the corre-
sponding word.
Read-only
Communications Port Error
Flags
A21900 to
A21907
ON when an error occurred during execution of a network
instruction (SEND, RECV, CMND, or PMCR). Turns OFF
then execution has been finished normally. Bits 00 to 07 cor-
respond 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
CPU Unit, a communications port will be automatically allo-
cated. The corresponding flag will be turned ON if an error
occurs and will be turned OFF if the simple backup opera-
tion ends normally.
