Ok, here is the first test program, download it, unzip it and have it ready to be transferred. When transferring it, you will be asked if you want to overwrite the existing program, answer yes. (you already have a plc program backup). After the transfer process, please request a plc RUN command from your PG.

This is a very small program wich contains only 2 blocks, OB1 and PB1.

OB1 is an unconditional order for your Sinumerik to process whatever is written into PB1.

PB1 are basically 2 ladder segments, wich I wrote according to your I/O list:

1.- When you press and hold the spindle jog CW pushbutton (I2.0), the chip conveyor (Q8.2) will start working.

2.-When you press and hold the spindle jog CCW pushbutton (I2.1), the machine worklight (Q64.0) will turn on.

I think your Sinumerik should be able to process this small program, if it doesn't then we'll have to try some other things.

I have tried the program as described by you and then ist cold start from the PG.As before all the LEDs turned OFF first and then turned On with the same alarm i.e 43 and green and red LEDs ON on the PLC CPU.I have also tried warm start but system goes OFF LIne.I have also checked the PB and OB block on the Controller and they are as you have send.I have also send these blocks one by one and without any problem.

What I have to do know.The program loaded sucessfully.But the alarm didnt go.The controller will work only if the alarms are gone.

Looking forward for your comments.

Last week I did an overall reset process to a Sinumerik 820 that was "frozen" as yours and it responded well right after the first steps of erasing and formatting the memory, it was also in STOP mode but it accepted the plc START request and then it got into RUN status without any problem.

I don't understand why your machine is not responding to anything.

Is it possible for you to post pictures of this control, from the operator panel front and rear and from the part where the Eprom modules are?

What version of PCIN were you using before, the one that you said was corrupted, what number is it?

I am attaching picture of 880 T controller

one more picture.

Another thing, after you downloaded the plc program and the % files to the Sinumerik, I hope you connected everything at the machine, this model of Sinumerik needs to be connected, otherwise it won't get rid of the stop status, In other words, you can not hope that the red led will go off without connecting everything first.

You can not request a "plc start" command from your pg when everything is disconnected, it will never RUN.

I still need you to tell me what version of PCIN you were working with.

Version of PCIN software is 2.0.
