Hello everyone. This is my first post here so please forgive me for any mistakes.
I am trying to rectify a Shaublin 180 CCn machine. the machine is in fault state for very long, the machine is displaying an alarm (1501 - Emergency Stop Pressed). The drives show no error just (--) on the power supply module and the servo amplifier.
I have tried the following in order to rectify the machine.
1) we tested the emergency pilot relay for the emergency loop. We have also tried replacing the same.
2) we tested the Power supply module. It was found fine.
3) we tried, traced and tested all the inputs and outputs of the I/o modules for any cuts or shorts.
4) We tested the door close switch and it's pilot relay. It was fine.
5) We checked the ladder. We found that the G8.4 was low, triggered by X8.4 signal which is also low this the system is not activating.
6) There are 2 I/o cards ( cartridge type) available and we have tried replacing them both but it did not help
7) we have checked all hydraulics and pneumatic lines.
8) we tested all the servo amplifier but it did not help.
9) now I am wondering if the problem is the interface card attached to the I/O card. Namely "A02" is an interface card attached in series to the I/o cards via J10B cable.
Please look at the attachments.
When I switched on the machine, and tried removing the cable between "CNC A05" and "A03" the system showed 'PMC Alarm' and a black screen.
Simultaneously when I removed the cable between (when the machine was restarted and was in emergency fault state) "A03" and "A150" a PMC fault was shown.
But when I removed the cable between "A150" and "A02" it shows no error or alarm. The interface keyboard"A06" attached to "A02" is also dead and no light is blinking unlike other keyboard "A04" which is lit. Please look at the image attached.
I am wondering if this is the issue. Should I change this interface card? I will have to buy a new card. But the indicator LED is lit on the card and I don't know how I can test it?.
Please help soon as it is really urgent as the machine is down for past 9 month and I am due to loose my job and my sanity.

there is a menu in the PMC menu that is called I/O DEVICES
Go check if all the I/o modules are online in the I/O LINK structure

Sir,
When we open the PMC menu we have an I/O option, after opening this option, we get a list of options namely devices, F-RoM, memory etc.
When we try to open devices option, we are getting an error 'I/o write error 30"
What does it mean ?

Sir,
When we are going to I/O link structure, there are channels which are showing,
1) channel 0- this shows other devices and displays supported
2) channel 1- this shows i/o devices and displays "not supported"
