Under Range and Over Range SCADAPack x70 independent of RAW and ENG values

[AlbertoArdila]

Hi

In Workbech there are the function RDFLD_I  (reads an point attribute or property and returns the value in a 32 bit integer variable). That function is used to get the Over Range and Under Range of an Analog input.

I want to know if in SCADAPack x70 Logic there is an equivalent.

In SCADAPack x70 Logic, I know that I can configure le Under and Over range in the Object input attributes but their limits are dependent on the Eng. Values.

I want that the under an over range are actives by the current (4 -20 mA values) example: 3.9 mA = Under Range and 4.1mA = Over Range and independents of the Raw and Eng. Configured values.

Thank you.

Hello Alberto,

Each x70 analog input may be configured as 0-20 or 4-20 mA easily. On the configuration tab, select Physical I/O then Local. Select the SCADAPack, then in the Channel Configuration column scroll down to the desired analog input. The type column is at the far-right. If using a smaller screen like a laptop that column might be hidden off to the right. See the attached image.

In RemoteConnect you may configure as many as four "Low" and four "High" levels (on the Alert Notifications tab) for each analog object. The values are assigned by you - they are not locked at (eg) 4.0 and 20.0 mA. 

In your logic you may use any or all of these as required. Also, these level values may easily be changed in logic at any time. Creating an object with a Logic Variable Type of T_SPx70_ADV_ANALOG provides access to these and many other attributes of the analog object.

Hi Joel Weder

Thanks for the reply

I go to use the Analog Input object properties for Over and Under Range Limit.
