I once wrote about a new employee, a graduate of an Electrical Engineering Program from a university, who, after only a short time on the job, quit his probationary period by merely justifying that his supervisor didn\u2019t even know what a PLC was…. The reason for quitting was that I asked him to get a PLC board… He went and came back saying there wasn\u2019t one. So, I asked him to look again because I had just seen it lying there. He came back saying there still wasn\u2019t one. So, I told him that the board in Picture 2 was the PLC board.<\/p>\n
<\/p>\n
I don\u2019t know if that was his real reason, but from the conversation, I think it was true, a genuine lack of knowledge. But he might have quit because I asked him to get it because I saw him sleeping on the job.<\/p>\n

Coming back to the PLC issue… Picture 3 is an explanation of the meaning of PLC, or PROGRAMMABLE LOGIC CONTROLLER… which should be translated literally as a controller that can set a sequence of operations according to pre-thought-out logic (very long!).<\/p>\n
<\/p>\n
Therefore, it is not incorrect to refer to Picture 2 as a PLC, because a PLC\u2019s function and application do not necessarily have to resemble the device shown in Picture 1.<\/p>\n
<\/p>\n
Many times, I\u2019ve brought up the topic… Distinguishing between Picture 1 and Picture 2 to determine which is the PLC (Programmable Logic Controller) \u2013 if you ask new employees or interns\u2026 almost 100% of them will give their answers as Picture 1. The percentage decreases only in recent years with the advent of AI, where employees start looking at the Picture before giving their answers\u2026 (despite the Picture clearly indicates the source).<\/p>\n

Why is that? Why don\u2019t they translate the English text before answering? This shows they\u2019re not using their ingenuity; they skip over the English and don\u2019t translate it because they don\u2019t think they need to, instead relying on familiar knowledge from classroom lessons.<\/p>\n
<\/p>\n
Does this mean that teaching methods haven\u2019t changed much or what?<\/p>\n
<\/p>\n
Intelligence and cleverness are different\u2026 In service work, you need an understanding of principles and theories, which can be called \u201ccleverness,\u201d and you need to identify problems and know which theory to use to solve them\u2026 That\u2019s what you might call \u201ccleverness,\u201d right?<\/p>\n
