Prob with Invensis Sys 8000

[inlinemd]

We seem to be having a problem with our Siebe Invensys 8000 system. It seems that we have lost communication with all of our micronet heatpump controllers on one of our integrators. We have two GCMs on this project with three integrators on each ASD bus. The problem we are having is involving integrator #1 address 32 on GCM #1 - all of the other heat pump controllers are operating normally with proper communication.

I did install a new integrator and that did not seem to solve the issue. We also went around and checked every controller to make sure the Ubus connections were all good - although I didn't think that would be an issue as if that were the case we would only have an issue with one controller.

Our Micronet application manual suggests that we may have lost comm with the GCM - yet all other components on the ASD bus are working good. Am I missing something here? Is there possibly a block in the GCM that may have been disabled? Thanks in advance for any assistance.

I assume you checked the micronet block in GCM. It should be enabled with correct address.
Can you see the all Micronet's with MN tool? Can you see see MNI?

Is there a specific micronet block for the integrator? I will check those blocks, I thought the MN blocks were just for the individual micronet controllers. We can use the Micronet software to go into an individual heatpump controller (that is not comm in Signal) and we can adjust setpoints, but it comes up that it is under local control.

Where would I be able to see MNI? Is this a block in the GCM for the integrator? It has been a while since I have messed with any of the blocks, if ever because we have never really had a problem with the original programming.

You should be able to see the all the devices under the MNI. Well even at another MNI. Hope my memory is correct, it's been a few years.
Micronet address (1) is (1:0) with MNI software. The next device (say 1) would be (1:1).
You should be able to see Micronet's on MNI (2)(3) or so on. For example you would type in address (2:0) to see the MNI (2) from a Micronet on MNI (1).

The MNFLO blocks are for the controllers the intergrator blocks are just MN. If you can do a node list and see other devices on the same integrator and the integrator comm light is flashing then everything is working and you have an addressing problem.


Here is the spreadsheet formula I keep in my PDA (dots are spaces)
