Setpoint operations are not automatically recorded in the event log. If you want to
have such operations recorded, you should explicitly specify the event logging action
when programming the setpoint, and what kind of setpoint operations to be recorded:
the setpoint activation, release, or both transitions. When such a setpoint is operated
or released, the instrument records the event operation and all subsequent setpoint
actions as separate events. The only exception is logging actions themselves that are
not recorded in the event log.
Each event log record keeps:
• date and time stamp (at one second resolution)
• event cause identifying the event type
• event origin identifying the point from where the event originates
• log value - the value of measured parameter that triggered the setpoint
• event effect identifying the action made on the event occurrence
• event target identifying the point to which the event action is intended
4.15.2 Data Logging
The PM295 provides data logging in 16 independent memory partitions, each
programmable to record from 1 to 16 parameters per record. Each partition can be
written independently allowing the user to record up to 256 parameters at once,
when using all 16 partitions.
For each data log partition, the user should configure the record format by
specifying a list of parameters to be recorded. Any measured parameter can be
recorded in the data log. For a list of available parameters, refer to Table 1-1.
Each data log record is date and time stamped at a 0.01 second resolution. Table 4-2
shows an example of the maximum amount of data that can be recorded in the data
log partitions, using different memory modules for records with 1, 4, 8, and 16
parameters, assuming the entire memory allocated for data log. By factory setting,
the memory module is configured for 16 data log partitions, each for recording 16
records with 16 parameters per record.
