Setting up and using the Custom Log (Cortex Series)

Before reading this article, we strongly suggest you read the Custom Log Explained article.

The Cortex offers a very flexible Custom Log feature that allows you to keep track of almost any I/O point or calculated value in the unit. 32 dedicated Custom Logs are available to be assigned to the I/O of your choice. For example: Metering inputs, Status inputs, SNMP GETs, relays, Math Functions, Logic Gates (VLG), and even Modbus device I/O’s (1MAxx, 2MRxx, etc.)

The 32 Custom Log inputs are identified with the letters CL, such as 1CL1, 1CL2, etc. As with every Davicom I/O, the numerical prefix represents the ID of the Davicom device it is associated with, and the numerical suffix represents the input number of the I/O.

For example, let’s look at a configuration where the temperature of a room must be logged over a period of time. We will use Metering Input 1A01, assume that it is already configured, and that a temperature sensor is connected to it.

To access the Custom Log setup menu, from the Cortex top menu, go to Logs > Custom Log Setup. The following screen appears. To add a Custom Log to configure, click on the Add (+) button.

Next, from the top ID drop-down menu, select the desired CL to be configured, or used the one that is already listed (auto-incremented). To check if a CL is already in use, select the desired ID from the list, then click on the Refresh button (round arrow): this will force a read of the selected input, and any configured content will come up. Select a different CL if required, and repeat the refresh process. Once a CL is chosen, click on the Disk icon to save it.

Once the desired CL is selected, set the different options as desired. For our example, we selected a sampling period (sampling rate) of 1 minute. For more detail about the settings found in this Custom Log configuration screen, see the Custom Log Explained article.

Once the setup up is done, the configured I/O appears in the Custom Log Setup screen.

Note that while there is no Description box in the Custom Log configuration screen, the description from the I/O that is assigned to the Custom Log input will show up in the Custom Log Setup screen, as seen in the image above.

To view the Custom Log entries, click on the Custom Log Views button.
