I am currently contracting as a Instrumentation Engineer for a very large engineering company, like with any other company this job has it's pro's and con's. Since I am doing the exact same job as an actual employed engineer my contract is only for 1 year and once the year is up I must take a 3 month "vacation" before being able to renew the contract for another year, also I know I shouldn't be surprised but I am amazed by how some of the common responses I get from the engineers and scientists that I work with are "I don't know", "I don't know how it works, it's a black box", "Why do you want to collect data, it should be plug and play".
That being said I really enjoy the work I am doing and I am really grateful for the opportunity that I have, but I struggle with whether I should work for a company or at least this section of the company with individuals that do not promote knowledge and at times it seems as though they actively try to hinder it.
I&C Engineering is a broad and a surprisingly deep field of study. These engineers deal with everything from actuator response dead times to instrument lag, network security, real time systems, Cv profiles of various valves, cavitation of pumps, packing materials for valves, steam flashing, and a whole host of many many topics related to instrumentation physics and limitations.
I am thankful when these people tell me "I don't know." I see it as being honest about what they're doing.
As for data collection, this is one of my recurring rants. I deal with a constant stream of nitwits who see all industrial control systems as a fountain of high fructose data that they want to suck on. They want all the data, all the time, to millisecond accuracy and performance. Why? Well that's when I get talk of synergies, sharing of information, and the ability of the boardroom to drill down to the specific faulty sensor (as if they really cared). The truth is that these idiots don't know what's going on; they don't want to look stupid in front of the people who actually do the work; so they gather all the data and hope that they can learn about this stuff without actually talking to anyone. This makes them feel smart. Yet, no matter how much data they get, they still won't understand what they're seeing. But don't try to tell them that.
The other rant about data collection is that it must be actionable. Otherwise it is a waste of everyone's money and time. Major events happen and then you get this flood of data that you have to sort through. This is especially the case with object oriented devices. Usually what happens is that some consultant specifies that it should generate alarms for every little thing because "someone might want to know that." And then a storm hits. The operations center is lit up with so many alarms that people seriously suggest using artificial intelligence to keep up and sort through what all these alarms mean.
I have a better solution: Create summary alarms and then send just those system alarms. Those systems should tell the operators who to send to where and with what resources. Any further data on the subject can be stored on site for forensic or diagnostic purposes. There is no good reason to collect and store it with the rest of the process data.
That response about data collection is from a voice of experience and understanding. Do Not Collect Data You Do Not Have An Immediate Operational Need For! It just confuses everyone. Been there, Done that, Got the T-Shirt, Wore it out, and threw it away.
Note: I am a control systems engineer with nearly 30 years of experience as a technician and as an engineer. I live with my creations. It keeps me honest. If our work fails in the middle of the night (and it has), I get called back to work. It has happened on Christmas Day at 5 AM. It has happened at many inconvenient times. We do everything we can to avoid such problems.
