Input Image Table and Tags

Expand the RFID_1:I by clicking the “+” box. This shows the input image table,

which has the following tags:

•AuxPwrFault – The AuxPwrFault bit will indicate if there is no auxiliary

power detected. A value of 0 indicates no fault, a value of 1 indicates a fault

condition.

•BlockFault – The Block Fault bit will indicate if any of the RFID channels

or input/output points is in a fault condition. A value of 0 indicates the

RFID channels and input/output points are functioning correctly, a value

of 1 indicates one or more of the RFID channels and/or input/output

points are in a fault condition. Individual RFID channel fault bits are

contained within each associated Channel[x] input word.

•Channel – See Input Channel Tags.

•Fault – The Fault word is a 4-byte value that will store the connection

status between the interface and the controller. A value of 0 indicates a

connection has been established, and value of -1 indicates no connections.

• ModuleStatus – The Module status is a 4-byte value that will contain the

overall status of the module. A value of 0 or 1 will indicate the module is

functioning with no faults, a value greater than 1 indicates a fault

condition exists. The ModuleStatus word will vary slightly based on the

configured unit.

• Pt00Data – The Pt00Data bit will indicate if the status of input point 0. A

value of 0 indicates open, a value of 1 indicates closed.

• Pt00InputFault – The Pt00InputFault bit will indicate if the input point

0 has a fault condition. Input faults would be Open Wire and/or Short

Circuit. A value of 0 indicates no fault condition, whereas a value of 1

indicates a fault condition.

• Pt00InputShortCircuit – The Pt00InputShortCircuit bit will indicate if

the input point 0 has an short condition. A value of 0 indicates no fault; a

value of 1 indicates a fault condition. Short circuit detection can be

enabled or disabled during configuration.

• Pt00NoLoad – The Pt00NoLoad bit will indicate if the output point 0

has a no load condition; No load detectioin only occurs when the output

point is OFF. A value of 0 indicates no fault; a value of 1 indicates a fault

condition. No load detection can be enabled or disabled during
