Hello,

I"m trying to use the C_NTED function over the DCS safety IO.
I have the SSO[5] tied to an SPI input [3], and the input is being made (@ symbol is shown) but I still get the DCS SSO NTED alarm whenever I try to enable the teach pendant in teach mode.
I've tried jumping out the input, and even using a different one with no success.

I've even tried tying the SSO[5] to the SSI[5], and that seems to work but once I tie any input to the SSO[5] signal it will not allow the robot servos to enable in teach.

Is there a parameter I may be missing? we are using the smaller 'b' cabinets so there is no hard wire NTED feature to get to, thats why i'm using the SPI and SSO[5] connections in the DCS safety logic.

Any guidance would help.

This is how I have my DCS safety IO setup (see attached). In my case, the safety signals are being controlled by the PLC.

If you're really hard pressed to jump it out, you can set SSO[5] = ON (JUST MAKE SURE YOU PUT IT BACK WHEN YOU ARE DONE TEACHING)

I'm not looking to jump it out permanately.
I'm looking for a solution as to why If I have any SPI input tied to SSO[5] then it doesn't work.

What is controlling your safety signals? Do you have a PLC?

Because if you do, the the PLC should send you a CSI that you tie to SSO[5]. For example SSO[5] = CSI[5]

I don't typically use SPI's in DCS

Unfortunately on this project we do not have a Safety PLC.
The SPI had to be used as a result.

I've tried contacting Fanuc but no luck with them yet either.
