Manual triggering
The recorder can be triggered manually via the LHMI or via communication by
setting the
Trig recording parameter to TRUE.
Periodic triggering
Periodic triggering means that the recorder automatically makes a recording at
certain time intervals. The user can adjust the interval with the
Periodic trig time
parameter. If the value of the parameter is changed, the new setting takes effect
when the next periodic triggering occurs. Setting the parameter to zero disables the
triggering alternative and the setting becomes valid immediately. If a new non-zero
setting needs to be valid immediately, the user should first set the
Periodic trig
time parameter to zero and then to the new value. The user can monitor the time
remaining to the next triggering with the
Time to trigger
monitored data which
counts downwards.
8.2.2.3 Length of recordings
The user can define the length of a recording with the Record length parameter. The
length is given as the number of fundamental cycles.
According to the memory available and the number of analog channels used, the
disturbance recorder automatically calculates the remaining amount of recordings
that fit into the available recording memory. The user can see this information with
the Rem. amount of rec monitored data. The fixed memory size allocated for the
recorder can fit in two recordings that are ten seconds long. The recordings contain
data from all analog and binary channels of the disturbance recorder, at the sample
rate of 32 samples per fundamental cycle.
The user can view the number of recordings currently in memory with the Number
of recordings monitored data. The currently used memory space can be viewed with
the Rec. memory used monitored data. It is shown as a percentage value.
The maximum number of recordings is 100.
8.2.2.4 Sampling frequencies
The sampling frequency of the disturbance recorder analog channels depends
on the set rated frequency. One fundamental cycle always contains the amount
of samples set with the
Storage rate parameter. Since the states of the binary
channels are sampled once per task execution of the disturbance recorder, the
sampling frequency of binary channels is 400 Hz at the rated frequency of 50 Hz and
480 Hz at the rated frequency of 60 Hz.
