I have recently hooked up a 3051 pressure transmitter to our delta v (rev13.3) test rack and recorded base line readings and calibration verification into AMS (13.5) and everything worked as expected.
Once complete the E/I technician powered down disconnected the analog wiring from the device prior to disabling the HART channel and deleting the tag from the test rack controller.
The same tag was then installing out in the process area under a new controller and the 4-20ma signal (percent field value )is being used and working in the module.
The channel is HART enabled and the device was auto sensed & the proper device and revision was identified, on the channel. Once I went into AMS and tried to scan that particular device and alert came up stating that AMS could not communicate with the device.
We could go out to the device and hook up to it with a 475 with no problem and configure the device locally.
My question is, why can’t I communicate with the device via AMS?
Is there a particular order to follow while setting up a HART device on a test rack, decommissioning it and the re commissioning it on a different controller.
thanks for your feedback in advance
