specify the time and day of the month for the Monthly Freeze Log Self-Read operation.
1) Daily Freeze Self-Read Time can be set to a zero value or a non-zero value:
 A zero value means that the Self-Read will take place at 00:00 everyday.
 A non-zero value means that the Self-Read will take place at a specific time of the day based on
the formula: Self-Read time = (Hour x 100 + Min) where 0 ≤ Hour ≤ 23 and 0 ≤ Min ≤ 59. For
example, the value 1512 means that the Self-Read will take place at 15:12 of each day.
2) Monthly Freeze Self-Read Time can be set to a zero value or a non-zero value:
 A zero value means that the Self-Read will take place at 00:00 of the first day of each month.
 A non-zero value means that the Self-Read will take place at a specific time and day based on
the formula: Monthly Self-Read Time = Day x 100 + Hour where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28.
For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th
day of each month.
4.5.5 SOE Log
The PMC-53A’s SOE Log can store up to 100 events such as Power-on, Power-off, Digital Input status
changes, Digital Output status changes, Setup changes and Setpoint events in its non-volatile memory.
Each event record includes the event classification, its relevant parameter values and a timestamp in ±1
ms resolution. The SOE Log can be displayed on the Front Panel and retrieved via communications. If
there are more than 100 events, the newest event will replace the oldest event on a First-In-First-Out
basis. The SOE Log can be reset from the Front Panel or via communications.
4.5.6 Data Recorder (DR) Log (Optional)
The PMC-53A optionally provides five Data Recorders capable of recording a maximum of 16 parameters
each. The Data Recorder Log is stored in the device’s non-volatile memory and will not suffer any loss
in the event of a power failure. The programming of the Data Recorder is only supported over
communications. Each Data Recorder provides the following setup parameters:
Setup Parameters
Value/Option
Default
Trigger Mode
0=Disabled / 1=Triggered by Timer
1
Recording Mode
0=Stop-When-Full / 1=First-In-First-Out
1
Recording Depth
1 to 10,000 (entry)
5760
Recording Interval
60 to 3,456,000 seconds
900 s
Offset Time
0 to 43,200 seconds, 0 indicates no offset
0
Number of Parameters
0 to 16
16
Parameter 1 to 16
See Appendix A for a complete list of parameters
See Appendix B
Table 4-13 Setup Parameters for Data Recorder
The Data Recorder Log is only operational when the values of Trigger Mode, Recording Depth,
Recording Interval, and Number of Parameters are all non-zero.
The Recording Offset parameter can be used to delay the recording by a fixed time from the Recording
Interval. For example, if the Recording Interval parameter is set to 3600 (hourly) and the Recording
Offset parameter is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour
every hour, i.e. 00:05, 01:05, 02:05…etc. The value of the Recording Offset parameter should be less
than the Recording Interval parameter.
