Siemens 545 Plc

[David_Emmerich]

Hi everyone. We have a problem with a TI/ Siemens 545 processor
That has sat outside unpowered for a year or so. It powers up, but is not in RUN mode... and the BATT is ng. I plan on putting in a new batt in the morning, but what I need to know is how do I get it back into RUN mode? Hint: we have no software for this...:site:

I'd guess that if the PLC was powered off and the battery was dead at the same time, your program is gone from the CPU.

Link in a thread earlier today with a post for the DOS based software. See the 5th post in the link.

I was hoping that there might be a hidden switch to put it into RUN mode...

There isn't, and like Blue said you've likely lost the program in the CPU as well.

Have a copy of the original plc program? or a printout?

We do have a floppy with the program, just have to get a good internet connection to download the TISOFT... Kind of hard out in the wilds of Mexico...
