Alarm Log; Basic Log (Pco1 Only If The Clock Card Is Installed - Pco2); Advanced Log (Pco2) - Carel pCO1 Series Manual

13 ALARM LOG

The program features two types of log: the BASIC log and the ADVANCED log.
13.1 BASIC LOG (pCO1 only if the clock card is installed – pCO2)
The significant availability of memory space on the pC01-pCO2 boards means that a series of events can be saved. The BASIC log can be
enabled by setting a parameter; if the clock card is not present (optional on the pCO1, embedded on the pCO2), the BASIC log is not available.
No other optional cards are used. A maximum of 100 events can be saved; on reaching the hundredth alarm, that is, the last available space in
the memory, the next alarm is saved over the oldest event (001), which is thus deleted, and so on for subsequent events. The saved events cannot
be deleted by the user, unless when installing the default values. The BASIC log screen is accessed by pressing the ALARM button when screen
E4 is displayed, and exited by pressing the MENU button (Esc on the Built in terminal). It has the following layout:
The following data are saved for each alarm, corresponding to the shelter at the moment of the event:
•
alarm description
•
time
•
date
•
chronological number of the event (0-100)
The chronological number of the event, in the top right corner, indicates how "old" the event is in the list of 100 events available. Event number
001 is first event to be saved after the BASIC log was enabled, and thus the oldest.
Move the cursor to the chronological number and then use the arrow buttons to scroll the alarm log, from 1 to 100.
For example, if event 001 is displayed, pressing the down arrow has no effect (end of the list).
If 15 alarms have been saved and event 015 is displayed, pressing the up arrow has no effect (end of the list).

13.2 ADVANCED LOG (pCO2)

The events are saved in the 1MB memory expansion, available on the pCO2 board. The advantages and characteristics of this log are as follows:
•
Log by event: a typical log by event is the alarm log. When an alarm is activated, the event is saved together with other significant values
(temperature, humidity, pressure, set point, etc.).
•
Log by time: a typical log by time is the temperature/humidity log. The temperature and humidity values are saved at regular intervals.
•
Log of logs: a typical log of logs involves the saving of the last alarms/temperature/humidity values recorded before a serious alarm.
Unlike the data saved for the log by event and log by time, this data is not overwritten when the memory is full.
•
Possibility to choose the values to be saved and the saving options at any time. The "WinLOAD" program can be used to define, using a
practical "Wizard", the values to be saved and the options. WinLOAD does not require the application program "files", as it is able to
directly receive all the information required from the program installed on the pCO1 – pCO2.
•
1MB dedicated FLASH memory. The system saves the data in the 1MB FLASH memory in the memory expansion (code PCO200MEM0).
For example, 1MB of memory is able to store 5000 alarm events with 5 values per alarm, and record 2 values, such as temperature and
humidity, for 6 months, saved every 5 minutes.
•
Possibility to define up to 7 different log configurations. Typically, each controller will have an alarm log, a log of the control values
(temperature/humidity/pressure) and some "logs of logs".
•
Possibility to display the data saved on the terminal LCD (external or built-in), or on a PC.
•
"Black box" function. The memory expansion that contains the logs can be removed from the pCO² on the unit controlled and inserted in
another pCO² to display the data saved. The latter pCO² does not need to have the same application program as the original.
•
Reliability of the data saved. The data are saved in FLASH memory, which does not require batteries that risk being discharged. If
following a software update the previously saved data are incompatible with the new software, all the data will be deleted (following
confirmation).
13.2.1 CONFIGURATION USING "WINLOAD"
The Advanced Log function, including all the options described above, is configured using the "On line help" feature in the WINLOAD32
program, the same used to upload the program software to the pC01 and pCO2 boards.
