Causes of ramp button runtime errors

If the button’s value is too large for the data type of the tag assigned to the Value connection, or if the value is outside the assigned tag’s minimum and maximum values, the application does not write the value to the Value tag and the application logs an error.

For example, the value is too large for the tag’s data type if the data source is a PLC-5, the value is 2,147,483,647, and the assigned tag is an integer tag using the address N7:0.

The digital tag works like a Boolean in that any non-zero value is treated as 1.

If the button’s value is beyond the Value limit (specified in the ramp button’s General tab), the new value is not written to the Value tag and the application logs an error.

If the Value connection is not assigned, when an operator presses the button the application logs an error.
