Error Flag
(Single

Function
ON when a network instruction
(SEND, RECV, CMND, or PMCR)
can be executed with the corre-
sponding port number. Bits 00 to 07
correspond to communications ports
0 to 7.
When two or more network instruc-
tions are programmed with the same
port number, use the corresponding
flag as an execution condition to pre-
vent the instructions from being exe-
cuted simultaneously.
(The flag for a given port is turned
OFF while a network instruction with
that port number is being executed.)
(When the simple backup operation
is used to performed a write or com-
pare operation for a Memory Card, a
communications port will be auto-
matically allocated, and the corre-
sponding Flag will be turned OFF.)
ON when a communications instruc-
tion can be executed with automatic
port allocation and there is a com-
munications port available for auto-
matic allocation.
These words contain the comple-
tion codes for the corresponding
port numbers when network instruc-
tions (SEND, RECV, CMND, or
PMCR) has been executed.
Words A203 to A210 correspond to
communications ports 0 to 7.
(The completion code for a given
port is cleared to 0000 when a net-
work instruction with that port num-
ber is executed.)
(When the simple backup operation
is used to performed a write or com-
pare operation for a Memory Card, a
communications port will be auto-
matically allocated, and a comple-
tion code will be stored in the
corresponding word.)
Turn ON when an error occurs in
executing an Explicit Message
Instruction (EXPLT, EGATR, ESATR,
ECHRD, or ECHWR).
Bits 00 to 07 correspond to commu-
nications ports 0 to 7.
The corresponding bit will turn ON
both when the explicit message can-
not be sent and when an error
response is returned for the explicit
message.
The status will be maintained until
the next explicit message communi-
cation is executed. The bit will
always turn OFF when the next
Explicit Message Instruction is exe-
cuted.
