The E3RELAY-DNET module template is designed as a starting point for configuring a module that accesses diagnostic parameters for a Allen Bradley E3 Overload Relay motor. The diagnostic data can then be used in control logic, such as creating an alarm to signal the need for operator intervention.
Device diagnostic parameters
The E3RELAY-DNET module template uses the Motor and Valve Module Faceplate (DL_FP) faceplate and the DNet_E3RELAY_dt detail display, which is functionally identical to the Motor and Valve Module Detail Display (DL_DTx) detail display, except that it creates an additional tab, named DEVICE, in the Diagnostics area of the detail display.
