For context, first time working with Siemens controllers and I finally got into the controller to view the programming, I have about 12 devices I need to organize a sequence of operations for (to help maintenance team understand devices at an existing building), starting with the chillers. I’m trying to think of ways to be more efficient and as someone who’s been programming for such a long time the block program takes so much longer for me to understand (especially like this).

Just from what I’ve seen there’s no real Control Basic program compiler or anything like that running where I might be able to view stored programs. Does line program exist in this environment? I’ve gone as far as to search the TIA files in hopes for something but nah.

Howdy everyone, my company has a small maintenance contract with a building that a few years ago, a controls company implemented a Siemens chiller plant controller. This controller has begun to act up, for some reason it's got priority 1 overrides on the chiller's isolation valves, continues to drop its IP comms unit reset, and I'd like to get into the programming to view this logic and maybe some runtime logs.

Long story short we tried to login to the device, but no credentials, and I thought that if we could get into the controller, we could view programs and see the logic behind it, however that was not the case and after some research we needed ABT Site to view this information.

BUT, now that I've got ABT site, I've found the place controller on the network, I'm stuck as to where to begin in viewing the programming. I've deducted that I would need to (Upload or Download) the configured device into my ABT Site, but I don't want to press the wrong one and send down a blank configuration. I've found a old siemens controller for practice but unfortunately didn't have Its IP to connect.

How would I be able to view the programming in this chiller controller? Do I upload from the device (this terminology sounds very backwards but I believe thats how its used), and then I can see how it was configured? Or do I press download to my computer (ABT Site) and view it.

OR is there an easier way to do this?

Thanks everyone, my first time working with the siemens environment.

Siemens TIA, does line programming exist?

How to view programming on a Siemens PXC4 with ABT Site?
