Address
A21300 to Turn ON when an error occurs in executing an Explicit Mes-
A21307 sage Instruction (EXPLT, EGATR, ESATR, ECHRD, or
ECHWR).
Bits 00 to 07 correspond to communications ports 0 to 7.
The corresponding bit will turn ON both when the explicit
message cannot be sent and when an error response is
returned for the explicit message.
The status will be maintained until the next explicit message
communication is executed. The bit will always turn OFF
when the next Explicit Message Instruction is executed.
A21900 to Turn ON if the explicit message cannot be sent when execut-
A21907 ing an Explicit Message Instruction (EXPLT, EGATR,
ESATR, ECHRD, or ECHWR).
Bits 00 to 07 correspond to communications ports 0 to 7.
The corresponding bit will turn ON when the explicit mes-
sage cannot be sent.
The status will be maintained until the next explicit message
communication is executed. The bit will always turn OFF
when the next Explicit Message Instruction is executed.
A203 to The following codes will be stored when an Explicit Message
A210 Instruction (EXPLT, EGATR, ESATR, ECHRD, or ECHWR)
has been executed.
A203 to A210 correspond to communications ports 0 to 7.
If the Explicit Communications Error Flag turns OFF, 0000
hex is stored.
If the Explicit Communications Error Flag is ON and the Net-
work Communications Error Flag is ON, the FINS end code
is stored.
If the Explicit Communications Error Flag is ON and the Net-
work Communications Error Flag is OFF, the explicit mes-
sage end code is stored.
During communications, 0000 hex will be stored and the
suitable code will be stored when execution has been com-
pleted. The code will be cleared when operation is started.
Address
A39212 ON when a communications error has occurred at the
peripheral port.
Note: This flag is disabled in NT Link (1:N) mode.
A52601 Turn this bit ON to restart the peripheral port.
A61901 ON while the peripheral port's communications settings are
being changed.
A52808 to These flags indicate what kind of error has occurred at the
A52815 peripheral port.
A39400 to The corresponding bit will be ON when the peripheral port is
A39407 communicating with a PT in NT link mode. Bits 0 to 7 corre-
spond to units 0 to 7.
A39408 to The corresponding bit will be ON for the PT that has priority
A39415 when the peripheral port is communicating in NT link mode.
Bits 0 to 7 correspond to units 0 to 7.
