Chassis Number
is configured for the Chassis Processor number which will match the Chassis to pull
the information. Valid chassis numbers are between 0 and 15.
Chassis Online
Bool Variable can be used to determine if any of the Chassis Processors of the selected
Chassis is operational or not. If the value of this variable is “True”, then it indicates that at least one of the
Chassis Processors in the selected Chassis is online and operational (Performing I/O).
Chassis I/O Errors
Bool Variable can be used to determine if any of the I/O cards configured in the user
application program for the selected cha
ssis have any errors. If this variable is “True”, then at least one
of the I/O card error status word is indicating an error condition.
Chassis Power Supply1
Errors
Boolean variable can be used to determine any failure on the left
(Primary) power supply.
If the value of this variable is “True”, then it indicates a failure on the left
(Primary) power supply. If variable value is equal to “False”, the left power supply is operating without
errors.
Chassis Power Supply1
(5 V)
Floating Point variable will report the 5 Volt power originating from the left
(Primary) power supply. The voltage on the left (Primary) power supply is adjusted to be 5.05 Volts ±0.05
Volts once every 10 seconds.
Chassis Power Supply1
(24 V)
Floating Point variable will report the 24 Volt power originating from the
left (Primary) power supply.
Chassis Power Supply1
Temp
Floating Point variable will report the board temperature on the left
(Primary) power supply.
Chassis Power Supply2
Errors
Boolean variable can be used to determine any failure on the right
(Secondary) power supply. If the value of this variable is “True”, then it indicates a failure on the right
(Secondary) power supply. If the chassis is configured for redundant power supplies and this variable
value is equal to
“False”, the right (Secondary) power supply is operating without errors.
Chassis Power Supply2
(5 V)
Floating Point variable will report the 5 Volt power originating from the
right (Secondary) power supply. The voltage on the right (Secondary) power supply is adjusted
automatically to be 4.95 Volts ±0.05 Volts once every 10 seconds. Once every 10 minutes, a test is
executed to see if this right (Secondary) power supply can take over.
Chassis Power Supply2
(24 V)
Floating Point variable will report the 24 Volt power originating from the
right (Secondary) power supply.
Chassis Power Supply2
Temp
Floating Point variable will report the board temperature on the right
(Secondary) power supply.
Chassis Backplane
(5 V)
Floating Point variable will report the 5 Volt power that is present on the
backplane for the I/O cards.
Chassis Backplane
(24 V)
Floating Point variable will report the 24 Volt power that is present on the
backplane for the I/O cards.
Processor Online
Bool Variable can be used to determine if the right (Primary) Chassis Processor is
operational or not. If this value is “True”, the right (Primary) Chassis Processor is online and operational
(Performing I/O).
I/O Path A Status
Bool Variable can be used to determine any failure on the communications link
between the selected right (Primary) Chassis Processor and Node Processors on Port A. If the value of
