Hi there!
This is something so old and having machine with it....... Last time unit was powered around 3yr ago and it did not work since than. now, we did reconect machine and i did told them there is posibility that battery is dead and maybe plc. After we did switch on the unit, PLC goes to RUN, battery is completly dead, but as I did check, unit is working and functions are ok. We still have some other things to fix, before we check machine completely.
Anyway, I would like to know what is stored with battery support on S5? I think main program is not, since plc is in RUN state and part of machine which we did test is working. Also, there is some card, red cover and labeled EPROM, since it is eprom, it should only erase by UV light.
Also, i will make RS232 to TTY interface to try it connect to pc. I know Step5 is in DOES, but i could use Windows variant from ibh soft, but don't know can i backup program from it?
