A receiver is in RX state and the receiver’s new input value is 01 hex (VOTE)
•
MCNRCD displays the Vote text for the receiver.
•
Because logging fields of both the RX state and the VOTE state are 0,
no error logging occurs.
•
MCNRCD stores a new state value of 01 hex for the receiver.
A receiver is in VOTE state and the receiver’s new input value is 11 hex
(DISABLE + VOTE)
•
MCNRCD displays the Err text for the receiver because there is no
definition for this input value (no input value match is found). This is
an error since a disabled receiver should not vote.
•
Because the logging field of the ERROR state is 1, an error will be
logged to the screen and/or disk, depending upon the logging option
settings.
•
MCNRCD stores a new state value of 05 hex for the receiver.
A receiver is in the DISABLE state and the receiver’s new input value is 01
hex (VOTE)
•
MCNRCD displays the Vote text for the receiver.
•
Because the logging field of the DISABLE state is 1, an error will be
logged to the screen and/or disk, depending upon the logging option
settings.
•
MCNRCD stores a new state value of 01 hex for the receiver.
9.12 Status Text Categories
There are some comparator display applications that also require monitoring and
control of non-comparator functions, such as alarm systems. The status message
text that is displayed for the alarm system can be different from the Vote, Rx, Dis,
and Fail status messages of the comparator system. MCNRCD can support these
non-comparator functions along with comparator display functions on the same
screen or on separate screens.
This is done by creating additional status text categories in the MCNRCD.CFG
file. Status text categories allow you to display different status message text for
different I/O modules. For example, in the example MCNRCD.CFG file shown
in Figure 34, an input value of 01 will cause the “Vote” status message to be
displayed. If an alarm category were also included in the file, the 01 input could
cause a status message of “ACTIVE” to be displayed. Each status text category
can have a number of text definition lines that define the status message text
displayed for that category, corresponding to the 16 combinations of four input
bits.
A new category is created in the MCNRCD.CFG file by entering the following
lines:
