Function
The completion code for a communications instruction is automat-
ically 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 commu-
nications completion code.
Stores the communications port numbers used when a communi-
cations instruction is executed using automatic communication
port allocations.
0000 to 0007 hex: Communications port 0 to 7
ON when an error occurred during execution of a network instruc-
tion (SEND, RECV, CMND, or PMCR).
Bits 00 to 07 correspond to communications ports 0 to 7.
ON: Error occurred
OFF: Normal condition
These words contain the actual input response times.
0 to 17 hexadecimal
When the Basic I/O Unit input response time setting is changed in
the PLC Setup while the PLC is in PROGRAM mode, the setting
in the PLC Setup will not match the actual value in the Basic I/O
Unit unless the power is turned OFF and then ON again. In that
case, the actual value can be monitored in these words.
Indicates the current status of I/O allocation, i.e., Automatic I/O
Allocation or User-set I/O Allocations.
0000 hex: Automatic I/O allocations
BBBB hex: User-set I/O allocations
ON: Error in CPU Bus Unit Setup
Turns OFF when I/O tables are generated normally.
ON: Error in CPU Bus Unit Setup
OFF: I/O tables generated normally
ON: Overflow in maximum number of I/O points
Turns OFF when I/O tables are generated normally.
ON: Overflow in maximum number of I/O points
OFF: I/O tables generated normally
ON: The same unit number was used more than once.
Turns OFF when I/O tables are generated normally.
ON: The same unit number was used more than once.
OFF: I/O tables generated normally
ON: I/O bus error
Turns OFF when I/O tables are generated normally.
ON: I/O bus error
OFF: I/O tables generated normally
ON: I/O table error because a SYSMAC BUS Slave cannot be
detected
Turns OFF when I/O tables are generated normally.
ON: SYSMAC BUS Slave missing
OFF: I/O tables generated normally
ON: Error in a Special I/O Unit
Turns OFF when I/O tables are generated normally.
ON: Error in a Special I/O Unit
OFF: I/O tables generated normally
ON: I/O detection has not been completed.
Turns OFF when I/O tables are generated normally.
ON: I/O detection has not been completed.
OFF: I/O tables generated normally
These words contain the maximum cycle time since the start of
PLC operation. The cycle time is recorded in 8-digit hexadecimal
with the leftmost 4 digits in A263 and the rightmost 4 digits in
A262.
