ASM1-3 Relay Controller Endnode stopped working

Products

I’m using the ASM1-3 endNode device with 4 onboard relays.

Everything was working great, I was using Node Red to send commands to the device to toggle relay states.

Suddenly it stopped responding. The LED still flashes blue when I send a command, but it does not respond. I connected via alphastation to see what was going on. When I go to “I2C Bus Scanner and ProXR Linker” then click “Scan I2C Ports” I get 0xFF. I have tried power cycling several times, but no change.

Any idea what is going on?

@ryan1 any idea what might be going on here

@ryan1 can you help please?

Do you have any idea what commands you were sending to the controller when it stopped working? I have not heard of this before in operation, but there are a number of functions that can stop the relays from working such as disabling automatic relay refreshing. I would suggest using Alpha Station to recover the controller. There is an extensive relay control command set (with full control panel) that you should use for testing. As for the I2C port scan, this may not be an immediate concern, I would dig into this deeper if you are unable to control relays from Alpha Station. If you want to return it to me, I am happy to look at the controller to see what has happened.

Thanks for the reply @ryan1
I was sending the following commands…
[0xAA, 0x07, 0xBD, 0x01, 0xFD, 0x0B, 0x01, 0x04, 0x00, 0x7C]
[0xAA, 0x07, 0xBD, 0x01, 0xFD, 0x0B, 0x01, 0x02, 0x00, 0x7A]
[0xAA, 0x07, 0xBD, 0x01, 0xFD, 0x0B, 0x01, 0x01, 0x00, 0x79]
[0xAA, 0x07, 0xBD, 0x01, 0xFD, 0x0B, 0x01, 0x00, 0x00, 0x78]

I was pressing buttons on a web page we created to trigger a function block in NodeRed which in-turn sends these commands. There are no other command sequences programmed to be sent, so we could not have sent any other command by accident. Like I said, the device was behaving as expected until suddenly It stopped responding as I was testing it.

How do I use Alpha Station to recover the controller?

I did all my initial testing in Alpha Station using the ProXR Enterprise Relay control panel.
I’ve gone back to this for troubleshooting. The Port and Bank are each set to 1, and when I press a button (to toggle a relay) on this page this is what I see…

  1. The on/off state display toggles between on and off
  2. In the communications section at the bottom of the screen I see new messages in both the Send field and the Receive field
  3. On the device itself, I see the Status LED quickly flash from Green to Blue then back to Green.
  4. The R4-R1 LEDs remain off
  5. The relays do not change state.

What else can I try?

I think it would be good to let our staff take a look at this, it sounds as though the relay portion of the controller is no-longer communicating with the CPU. @jacob can you assist with an RMA?

Hi,

You can submit an RMA from: NCD Login - NCD.io

Okay, Thank you. I will submit an RMA.
