Bit 0
Card Timeout Error
This bit indicates that there was no response from the I/O card. The card is not returning
a ready test signal, is offline, or has been removed from the chassis. This bit sets the
Card Error Latch (Bit 14).
Float Temperature Input
The Board Temp is a floating-point value, which equals to the operating temperature in Degrees
Celsius as measured by an on-board sensor. User applications can implement customized limits
for alarms and annunciations by examining the value of this variable. NetArrays assigns a default
Tag to this variable when the card is added to the I/O configuration. Reassign this Tag as
required to access this board temperature in the project program.
Integer Card Revision
The card revision is an integer value, which equals to the revision number of the PLD code.
NetArrays assigns a default Tag to this variable when the card is added to the I/O configuration.
Reassign this Tag as required to access this card revision in the project program.
Integer Readback Status
The bits of this Int input represent the last output states written to the card. A 1 indicates that the
output is energized (on); a 0 indicates that the output is de-energized (off). NetArrays assigns a
default Tag to this variable when the card is added to the I/O configuration.

Integer Switch Fault Detection
The Switch Fault Status returns the result of the Switch Fault Testing on the 16 AC output
channels. A 1 indicates a Stuck-ON condition. A 0 indicates a normal condition. If a particular
channel is OFF then the corresponding Switch Fault bit will be 0 and there could be a Stuck-ON
condition but the Switch Fault Test is not able to detect it. However, in this case there will be a
readback error on the channel.
