USYUL01 having PM1 Communication Error                                                

This machine encountered error PM1 not ready. Upon check found PM1 lost comm to the main frame. Reset machine and initialized but still PM1 unable to communicate.            

We remove power on PM1 controller and reset again, negative. Try change hdd from slave to master, -negative                                  

So we put back master hdd and tried swap line card on the controller. Upon removing IOB-80 card, found some burn mark on component                 

Continue change the card, and reset but still PM1 unable to communicate. Change the whole PM1 controller, still negative                                 

Other modules are ok and seems working fine. Checked PM1 LAN connection and LAN router unit. PM1 no link to router. Swapped LAN cable and tested cable is ok.                                    

Proceed to change CPU card(mother board), PM1 able to link to router but still no comm. Again changed another HDD -ve. put back original HDD.                               

Renamed Persistent Materials and Persistent DataMC folder then reboot PC -ve. Renamed ":CWmanuserPM1datalogger.dat" and reboot PC -ve.           

Find automation failed due to chambers offline error even though P2 to P6  are    

online except P1 chamber. Recipes are checking ALL chambers to be online.
