Address
A40210
ON when there is a setting error in the PLC Setup.
A406
When there is a setting error in the PLC Setup, the location
of that error is written to A406 in 4-digit hexadecimal. The
location is given as the address set on the Programming
Console.
Address
A40213
ON when the Detect Interrupt Task Errors setting in the PLC
Setup is set to "Detect" and one of the following occurs.
IORD(222) or IOWR(223) in a cyclic task are competing with
IORD(222) or IOWR(223) in an interrupt task.
An interrupt task is executed for more than 10 ms during I/O
refreshing of a C200H Special I/O Unit or a SYSMAC BUS
I/O Unit.
IORD(222) or IOWR(223) was executed in an interrupt task
when I/O was being refreshed.
A42615
Indicates the cause of an Interrupt Task Error.
A42600 to
The function of these bits depends upon the status of
A42611
A42615 (the Interrupt Task Error Cause Flag).
A42615 OFF:
Contains the interrupt task number when an interrupt task
was executed for more than 10 ms during I/O refreshing of a
C200H Special I/O Unit or a SYSMAC BUS Remote I/O Unit.
A42615 ON:
Contains the Special I/O Unit's unit number when an attempt
was made to refresh a Special I/O Unit's I/O from an inter-
rupt task with IORF(097) while the Unit's I/O was being
refreshed by cyclic I/O refreshing (duplicate refreshing).
Address
A40212
ON when an error has occurred in a Basic I/O Unit.
A40800 to
Contains the binary slot number where the error occurred
A40807
when an error has occurred in a Basic I/O Unit.
A40808 to
Contains the binary rack number where the error occurred
A40815
when an error has occurred in a Basic I/O Unit.
A40110
ON when an Input Unit has been installed in an Output
Unit's slot or vice-versa, so the Input and Output Units clash
in the registered I/O table.
A40209
ON when a Basic I/O Unit registered in the I/O Table does
not match the Basic I/O Unit actually installed in the PLC
because a Unit was added or removed.
A40900 to
The corresponding flag will be turned ON when an Expan-
A40907
sion I/O Rack's starting word address was set from a Pro-
gramming Device and two Racks have overlapping word
allocations or a Rack's starting address exceeds CIO 0901.
Bits 00 to 07 correspond to Racks 0 to 7.
A40111
ON when the number of I/O points being used in Basic I/O
Units exceeds the maximum allowed for the PLC.
