3.2.4 Reading Alarms

The module will automatically read alarms received from DPV1 slaves into

specific controller tags.

When the ladder recognizes that the module has received a new alarm, the

module will latch the MVI56PDPMV1.Util.CurrentAlarm.15 bit. The sample ladder

logic will automatically recognize that the module has an alarm pending and

execute a message instruction to poll for the alarm.

When the message is successfully executed the ladder logic will increment the

following controller tag:

MVI56PDPMV1.Util.MSG.GetAlarm.DNCounter.ACC

If the message is not successfully executed the ladder logic will increment the

following controller tag:

MVI56PDPMV1.Util.MSG.GetAlarm.ERCounter.ACC

The error code will be copied to the following controller tag:

MVI56PDPMV1.Util.MSG.GetAlarm.LastError

The alarm data will be stored in the MVI56PDPMV1.Mailbox.Alarm controller tag

structure:

1 2 ... 138 139 140 141 142 143 144 145 146 147 148 ... 254 255
