The status of this register should be used for information only, as a means
of determining if the system is ready for operation.
Note: If a bit is on, it indicates a problem with the associated device. If
the input is associated with a loop or limit control, check the
corresponding loop or limit operational status register to determine the
cause for the alarm.
For monitor points, check input wiring to determine if the signal is within
the proper range for the input configuration.
Note: If a bit is on, check the corresponding loop / limit communication
wiring/settings to determine the cause for the alarm.
For Bit1 and Bit2, the device associated with the error is dependent upon
the system configuration. If the MCT4 is a single loop control with the
limit installed, Bit1 will represent an error code on the limit control. If the
MCT4 has two control loops configured with monitor points and no limit,
Bit1 will represent an error on loop 2 while Bit2 represents an error on the
monitor card.
