Hi,
Have very basic knowledge of PLC's. Wondering if someone can point me in the right direction.
Our assembly equipment is being run off of this PLC. One day the machine just turned off. I go look at the plc and the power supply is blinking "PWR".
I have checked the connections going into it and it's receiving the 120. I even hooked up a separate 120v power source to rule out bad input voltage.
The power supply is IC693PWR321T and the base plate/cpu is IC693CPU323T.
One thing I noticed is that I took the power supply off for a minute from the base (it says on the base plate that if left out the power supply for more than an hour then the memory might be lost, so I was careful with this to do it quickly) and when the power supply is disconnected from the back plate then it shows a solid PWR led. But when I reseat the power supply back to the back plate, the PWR led blinks as in the video.
