The Run light on my TI System 505 model 545 PLC has switch off how do I go about turning it back into the run mode. What could have caused it to go off?

In order to get it to transition to run mode, you will need one of 3 software packages: Tisoft, Softshop or APT. (There is no way to put the PLC in run mode from the hardware itself)
As for what caused the PLC to stop, you haven't supplied enough info to determine that. There are a number of things that can cause a stop, most of them being hardware faults.

Many possible reasons:
1) Battery is low and you got a power outage. Your program is lost.
2) Hardware malfunction
3) Somebody switch it in program mode

Check the BATT led. If it's not lit, then cause is 1)

If you suspect a hardware malfunction, use Tisoft to get PLC status.
If the CPU GOOD led is not lit, disconnect the battery (DIP switch) and power up. If CPU GOOD does not come on, replace your CPU.

To put it back in RUN mode, use Tisoft
