EMERGENCY EXIN

M01 OPERATION ERROR XZ

According to the electrical diagram, hard over travel switches are optional & are missing in machine.
In diagnosis mode, checked other inputs like cycle start , mode change switch which are ok.
Surprisingly no any out put is being generated.
Tried to check the PLC ladder but it is not being open. When searched any input like X29 or similar it shows ERROR.
When tried to check PLC size it shows
LINK 0 / KBYTE
LADDER 0 / KB
MESSAGE 0/ KB
I loaded all data by floppy even then it shows the same alarm. ( path c:/ncbac )

Next Day Work::stickpoke

To-day I reloaded all the data, but still no improvement & same alarm is being displayed.
In Meldas Magic screen tried to open the PLC ladder.
Sequence ... Ctr + F , Menu , 9main, monitor , NO / NC , X1F & enter it shows Prog not found.


When I tried to search by Rung No. 100,
PLC ladder is being displayed but when I checked whole ladder, no any X or Y contact was found.


I am quite confused, pl help.
In seven segment display of controller it shows " A "


( Can we load the data with the help of RS232 port.)

PL send your suggestion to solve the problem..
