Set up acknowledge bits in any of the following ways:
one acknowledge bit for each tag
When an alarm is acknowledged on one RSView32 station, that
alarm is automatically acknowledged on all other RSView32
stations. Keep in mind, however, that RSView32 will be
monitoring each bit so using many acknowledge bits can result in
substantial system overhead.
one acknowledge bit for a group of tags
When an alarm is acknowledged on one RSView32 station, all
alarms associated with the acknowledge bit are automatically
acknowledged on all RSView32 stations. Keep in mind, however,
that RSView32 will be monitoring each bit so using many
acknowledge bits can result in substantial system overhead.
one acknowledge bit for all tags
When any alarm is acknowledged on one RSView32 station, all
alarms are automatically acknowledged on all RSView32 stations.
This means alarms cannot be acknowledged individually.
Therefore, the Acknowledge command and the alarm summary’s
Acknowledge button have the same effect as the AcknowledgeAll
command and the Acknowledge All button.
To set up acknowledgment, use the Acknowledge Bit field in the
Advanced tab of the Analog Alarm and Digital Alarm editors. Or, to
set up global alarm acknowledgment without using acknowledge bits,
use the global alarm acknowledgment features in the RSView32 Active
Display System, available separately from Rockwell Software.
Handshake bit
When a tag goes into alarm, RSView32 can set a handshake bit to
notify a programmable controller that the tag is in alarm. To set up
handshaking, use the Handshake Bit field in the Advanced tab of the
Analog Alarm and Digital Alarm editors.
