Scaling, Formating, Limiting, Lookup Tags and more...

A new set of tag attributes are being added to ScadaMobile to fulfill a series of requirements aimed at enhancing the flexibility of the product and to give a better experience to users. A feature to lookup texts form a table, and the ability to access serial modbus devices through gateways is being incorporated too.

Scale. The scale attribute will allow to represent values in engineering units that differ from the raw data present in PLC. With the scale attribute you specify raw and engineering units. The raw units are converted (scaled) to an engineering value on display by applying a linear transformation.

Format. To display numerical values with a particular width and precision, including leading zeros. Combined with the scale attribute it will make possible to represent process values such as flow, pressure, voltage, temperature and so on in a more appropriate way.

Bounds. To constrain engineering values between two limits in order to prevent users entering out of bounds data.

Lookup Tags. A new feature in ScadaMobile that will allow a tag to pick up a text string from a previously entered lookup table based on its current value and display such text instead of the tag itself. With this feature, presenting dynamic, customized text messages to the user, such as process or alarms conditions, will be possible.

Slave_id. This attribute will add a way to connect to modbus serial devices that are accessible through TCP gateways. By specifying slave ids in tags, ScadaMobile will group and direct all messaging to the appropriate end devices so data coming from all of them can be monitored.

These attributes will be supported from version 1.3.1, which is soon to be released.
