The following table and descriptions cover the words and bits in the Auxiliary
Area of PLC memory that are related to the Ethernet Unit.
Name
Bits A202.00 to A202.07 turn ON when a network
instruction (SEND, RECV, CMND, or PMCR) can be
executed with the corresponding port number. Bits
00 to 07 correspond to communications ports 0 to 7.
These words contain the completion codes for the
corresponding port numbers when network
instructions (SEND, RECV, CMND, or PMCR) have
been executed. Words A203 to A210 correspond to
communications ports 0 to 7.
Bits A219.00 to A219.07 turn ON when an error
occurred during execution of a network instruction
(SEND, RECV, CMND, or PMCR). Bits 00 to 07
correspond to communications ports 0 to 7.
Bits A302.00 through A302.15 turn ON while the
corresponding CPU Bus Units (Units #0 through
#15, respectively) are initializing. The bits will turn
ON either when power is turned ON or when a CPU
Bus Unit Restart Bit (A501.00 to A501.15) is turned
ON.
Bit A402.03 is turned ON when the CPU Bus Units
actually installed differ from the Units registered in
the I/O tables. The ERR/ALM indicator on the front
of the CPU Unit will flash, but CPU operation will
continue.
The unit number of the CPU Bus Unit involved is
stored in word A427.
Bit A402.07 is turned ON when an error occurs
during the transmission of data between the CPU
and CPU Bus Units. The ERR/ALM indicator on the
front of the CPU Unit will flash, but CPU operation
will continue. The Unit where the error occurred will
stop.
The unit number of the CPU Bus Unit involved is
stored in word A422.
When a memory error occurs, the Memory Error
Flag (A401.15) is turned ON and one of the follow-
ing flags is turned ON to indicate the memory area
where the error occurred.
A403.00: User program
A403.04: PLC Setup
A403.05: Registered I/O Tables
A403.07: Routing Table
A403.08: CPU Bus Unit Settings
The ERR/ALM indicator on the front of the CPU Unit
will light and CPU operation will stop.
The Duplication Error Flag (A401.13) and the
corresponding flag in A410 will be turned ON when
a CPU Bus Unit's unit number has been
duplicated. Bits 00 to 15 correspond to unit numbers
0 to F.
The ERR/ALM indicator on the front of the CPU Unit
will light and CPU operation will stop.
