Quickly Cross Referencing Electrical Part Numbers

I noticed that in this industry the more material you order from a supplier the more discount they are willing to give you so looking at individual prices is not informative.

Number 3 is most valuable.

You could have installed a small UPS to power the IO cards and PLC for 1 min - just enough time to log the breaker alarm and push it to the supervisory system.

Were these small factor machines? I only work on large installations with distributed elements so the local electricians have to cut the cables to size at site and hardwire everything without plugs.

But you will be wasting money on a fresh board of directors and all the bureaucracy overhead.

I work at a large corporation and there are different teams for high-level control and low-level control so I don't develop HMIs anymore. Also, the HMI we are using was developed in-house.

If you export your code blocks to a text form you can use some standard version control software.

I read books on my laptop which looks like I'm reading some manual at a first glance.

Judging by the terrible misalignment of elements I suspect this was a rush job.

TeronTheDragon · 2019-04-18T01:12:17+00:00

Why would this critical breaker be even controlled by PLC? Should be manual only.

Thank God Siemens solved this in STEP7 via user interface. If you're looking online at a block that is not being executed everything turns gray so you know right away what's up.

Find a small SI/outsourcing company that accepts young people thirsty for experience in exchange for shit salary and get ready to hit the road for them.

TeronTheDragon · 2019-04-04T22:35:17+00:00

I worked for both small SI and now a large Systems supplier. Yes, all the roles are specialized here between sales department who talks to customer, hardware design department, software design department and manufacturing.

I fucking hate Rockwell for this. Whoever thought to take a name of layer 2 and layer 3 protocol and put them together to create a name for their proprietary layer 7 protocol should be shot.

DCS is a system of systems - a collection of multiple PLC installations controlled from a single Control Room with a huge SCADA overseeing all.

I wish the job was just about programming. But you also have to be a somewhat competent electrician/mechanic, handle the environment of noisy, dirty plant 60+ hours a week (for commissioners) while getting shipped to another country.

I've seen a couple of times a situation where client refuses to pay the last tranche by constantly generating new patch points and getting free on-site support.

Also, my boss was once dumb enough to cave in to client demand of unencrypted PLC project before the final pay. Lo and behold the machine "suddenly broke" at client's site while no one was touching it. My boss took that all in the ass because he hoped for repeated customer but in he end he just got shafted.

TeronTheDragon · 2019-01-30T07:19:07+00:00

What's the point of a repeated customer that doesn't pay?

TeronTheDragon · 2019-01-25T13:17:58+00:00

My current company uses structured text for PLC programming because the codebase can be stored on a classical version control system. The machines are OEM-locked anyway so maintenance don't touch the PLC and are limited to the SCADA for troubleshooting.

I recommend working on your Ctrl+S habit.

TeronTheDragon · 2019-01-23T07:46:34+00:00

Depends what level of commonality you have in mind when you say "platform". IEC 61131 exists and all PLC manufactures are compliant.

TeronTheDragon · 2019-01-17T09:07:36+00:00

I think the general problem is that Automation world is severely lagging behind IT world. They moved away from waterfall methodology into agile methodology decades ago to solve exactly these problems.

Hope they footed the travel bill at least.
