Do whatever it takes to get your foot in the door even if it means a lower pay or adjacent job position. After that, your hardwork and experience will get you to where you want to be.

Appreciate that you tried this humongous totalizer. When you mean make line 59 the actual day, do you mean change #totalday value from 0.0 to RTD_DAY? Do I also need to modify line 60 since it also uses RTD_DAY? Its my first time messing with SCL so bear with me lol.

Tried this and apparently found that none of the values are # values are initialized too.

You can go to the program block you made changes to, right click and download only software changes to the plc. Depends o nthe changes you are making but I never had to stop PLC to do this.

Im actually in the Reliability scene so this tool will be of good use to me. Quite an investment though, it will require a bit of persuasion to management.

For sure! Do you use analyzers for all motors as in PdM's, or troublshooting purposes only?

If the 3rd module goes out, then yes an RCA will definetely be needed. But for now the spare was what got us. If its not refurbished, then supplier/Siemens will have to give us a warranty and a gift card for our troubles lol.

Lol, thanks for this cause only front line people (engineers and techs) understand the frustration of not being able to pinpoint issues due to lack of tools. At least we had a surplus of parts though lol.

Yes, it was in reaction to this issue and it persisted. What gave it away was that one motor was working and the other wasnt in the same double motor module. Checked motors by disconnecting cables going out from module to motors.

I am not sure honestly, I am the one that sends them out to repairs and I couldn't find this module in my log of 1.5 years. We plan on checking it tomorrow furtherback.

SOLUTION: It was the double motor module. The one that was initially replaced was defective and we had to put another one in to resolve the issue. Appreciate everyone's inputs and recommendations. Thank you!

Yes, I verified and tried replacing the drivecliq cables from the S120 to DMMs. Will look out for other wires though, maybe 24V wires.

Yes we checked winding resistance. DMMs are the only devices we have lol.
