This is a special preset option. To use it, you must first define multiple service modes within the operational mode of the pump. Additionally, you need to establish several price groups. The service modes available to a fueling point must include the price group ID that you wish to preset. All these requirements will be explained in the following example.
You can always check the price for each nozzle at the fueling point control. Simply hover your mouse over the nozzles, and a tooltip will pop up displaying the grade ID, name, and current price.
In previous transactions, this price was used to calculate the total amount for the fuel. It is the price defined for price group 1 (pg:01 in the status table).
We will now preset the next fueling price from price group 3. According to the settings for the price groups, at the end of operation the price should be set to 1.001.
To enable this, the price group 3 must be available for the active operation mode. We need to add a new service mode and set the price group to 3 (PG Id) for that mode, as illustrated in the picture below.
Only then can the selection of a price group be successful, as DOMS checks if this group is allowed for that particular fuelling point by verifying if it is included in any of its service modes.
After confirming this input, the fueling point is authorized, and its price group has been changed to 3, as indicated by "pg:03" in the list of statuses.
The price from price group 3 will be used for transactions made with these settings. This preset option allows you to use the price for a specific grade from a different price group for your next fueling. There are no volume or monetary limits associated with this type of authorization. After completing the transaction authorized with this preset, the price group will revert to the value defined for the active service mode.
