Hello, I have a BP interact 412 with Fanuc O-mate M control that I am trying to revive from the dead.
I recently purchased this machine and it came with a few missing buttons and the interconnect circuit board/wiring from the control panel.

I wired in everything by hand using the system schematic which was pretty straight forward.

Upon first power up there was an alarm about RAM parity error which was due to backup battery going low. I reentered all the parameters by hand and the alarms went away. Now when I power on the machine it comes up with "not ready" message but no alarms associated with it.
I have checked all the LEDs and voltages on all the board and everything checks out. So I was pursuing the emergency stop circuit. which also seems to check out but the system is stuck in the "not ready" state. So my question is what exactly does control need to see it order to be "ready"?
Reading the Fanuc maintenance manual it looks like I should be able to check diagnostic address diag0021 to see the e-stop or external reset signal status.

So on power up I get
DGN0021 0 0 0 0 0 0 1 0
DGN0701 0 0 1 0 0 0 1 0
I think this is expected until the "power ON" button is pushed (correct me if I'm wrong)
However pushing the "power ON" button does not turn on the power and is because the control is not energizing the "NC Ready" relay 2CR which in turn prevent energizing of "power ON" relay 1CR.

This is sort of chicken and the egg problem and I figured I'll try something and see what I can learn. I should mention, that I physically verified all of the physical wire connections and relays.
I decided to force the "NC ready" relay ON. In doing so it allows for the "Power ON" circuit to work and stay lit. Also the "not ready" meaasge goes away, the axes drive turns on the DRDY LED and I get the following screen
but no prompt for homing the axis.

The diagnostic bits change to "all clear" when the "NC ready" relay is forced ON to
DGN0021 0 0 0 1 0 0 1 0
DGN0701 0 0 0 0 0 0 1 0
I suspect that by forcing the "NC ready" relay ON I'm getting rid of the "not ready" message but hte NC is still truly not ready due to some other reason. Which is why my original question, what does NC need to see in order to be "ready"?

I have another concern which might explain things, it is the fact that the PMC slot is empty on this control. From the Fanuc documentation it seems to me that O-Mate C system uses PMC. Can someone say for certain that this is reason for the problem I describe above?
Would the PMC have any cables going to it or it only makes connection at the main board connector? There isn't any unconnected cable inside the control cabinet and the wiring diagram supports that.

I have contacted several owners of BP Interact machines in hopes of clearing up the PMC question but no one has responded yet.

Any help is appreciated.
