Name Address Description Access Updated
Network Communications
Port Allocation Enabled Flag A202.15 ON when there is a communications port available for
automatic allocation.
Note Use this flag to confirm whether a communica-
tions port is available for automatic allocation
before executing communications instructions
when using 9 or more communications instruc-
tions simultaneously.
Read-only
First Cycle Flags after Net-
work Communications Fin-
ished A214.00 to
A214.07 Each flag will turn ON for just one cycle after communi-
cations have been completed. Bits 00 to 07 correspond
to ports 0 to 7. Use the Used Communications Port Num-
ber stored in A218 to determine which flag to access.
Note These flags are not effective until the next cycle
after the communications instruction is executed.
Delay accessing them for at least one cycle.
Read-only
First Cycle Flags after Net-
work Communications Error A215.00 to
A215.07 Each flag will turn ON for just one cycle after a communi-
cations error occurs. Bits 00 to 07 correspond to ports 0
to 7. Use the Used Communications Port Number stored
in A218 to determine which flag to access. Determine the
cause of the error according to the Communications Port
Completion Codes stored in A203 to A210.
Note These flags are not effective until the next cycle
after the communications instruction is executed.
Delay accessing them for at least one cycle.
Read-only
Network Communications
Completion Code Storage
Address A216 to
A217 The completion code for a communications instruction is
automatically stored at the address with the I/O memory
address given in these words.
Place this address into an index register and use indirect
addressing through the index register to read the com-
munications completion code. Read-only
Used Communications Port
Numbers A218 Stores the communications port numbers used when a
communications instruction is executed using automatic
communication port allocations.
0000 to 0007 hex: Communications port 0 to 7 Read-only

Peripheral Port Communica-
tions Error Flag A392.12 ON when a communications error has occurred at the
serial port 1. Read-only
Peripheral Port Restart Bit A526.01 Turn this bit ON to restart the serial port 1. Read/write
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
(No-protocol Mode) 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
