Information on Explicit Message Instructions
Serial Port 1 Information
Name Address Description Access Updated
Explicit Communications
Error Flag A213.00 to
A213.07 Turn ON when an error occurs in executing 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 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 mes-
sage communication is executed. The bit will always turn
OFF when the next Explicit Message Instruction is exe-
cuted. Read-only
Network Communications
Error Flag A219.00 to
A219.07 ON when an error occurred during execution of a net-
work instruction (SEND, RECV, CMND, or PMCR).
Bits 00 to 07 correspond to communications ports 0 to 7.
The ON status is retained until the next network instruc-
tion is executed.
Read-only
Network Communications
Response Code 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 corresponding word will be cleared when back-
ground execution has been completed.)
Words 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
Network Communications Error Flag is ON, the FINS
end code is stored.
If the Explicit Communications Error Flag is ON and the
Network Communications Error Flag is OFF, the explicit
message end code is stored.
During communications, 0000 hex will be stored and the
suitable code will be stored when execution has been
completed. The code will be cleared when operation is
started.

Peripheral Port Settings
Change Bit A619.01 ON while the serial port 1’s communications settings are
being changed. Read/write
Peripheral Port Error Flags A528.08 to
A528.15 These flags indicate what kind of error has occurred at
the serial port 1. Read/write
Serial Port 1 Send Ready
Flag
(No-protocol Mode)
A392.13 ON when the serial port 1 is able to send data in no-pro-
tocol mode. Read-only
Serial Port 1 Reception
Completed Flag

A392.14 ON when the serial port 1 has completed the reception in
no-protocol mode. Read-only
Serial Port 1 Reception
Overflow Flag
(No-protocol Mode)
A392.15 ON when a data overflow occurred during reception
through the serial port 1 in no-protocol mode. Read-only
Peripheral Port PT Commu-
nications Flags A394.00 to
A394.07 The corresponding bit will be ON when the serial port 1
is communicating with a PT in NT link mode.
Bits 0 to 7 correspond to units 0 to 7. Read-only
Peripheral Port PT Priority
Registered Flags A394.08 to
A394.15 The corresponding bit will be ON for the PT that has pri-
ority when the serial port 1 is communicating in NT link
mode. Read-only
Serial Port 1 Reception
Counter
(No-protocol Mode) A394.00 to
A394.15 Indicates (in binary) the number of bytes of data received
when serial port 1 is in no-protocol mode. Read-only
