Dear All,
I bought an old S5 PLC from auction. Part no. 6ES5 928-3UB11
when i power it up. it's Stop led is blinking and basp led is on.
So i perform an overall reset and warm restart but it didn't solve the problem.
stop led is still blinking.
when i try to upload program from the PLC. The PLC is fully Blank.
but when i tried to download a sample program. It is showing Memory Full.
If i compress memory. the communication is lost.
What could be the problem?
