@MsMOSA2010 Naturally there is more to be learned about this subject than we can cover in just a ten minute "preview" video. If you have questions you should post them on one of the free public forums listed on the "Resources" page of my website. There are many knowledgeable people there who can help you. Also did you watch just this one lesson? There are 11 which should all be watched IN NUMBER ORDER as a continuing series. Skipping around will not be as helpful to you.
ive never had the opportunity to play with one of these toys, never learned a thing about them til now, but everything is clearly explained & intuitive. wonderful job sir!
WRONG! The when the OTE is F (False) it is not telling it to write a zero, it is just natrually 0 as the relay output in the PLC will fall out and be in a de-energised state. it will only energise when the output is set to 1
Greetings Marine8819. So how do you explain why a field output device will remain ON if the OTE controlling it is deleted while it's true? See the example which starts at time 3:00. The actual reason is that the deleted OTE is unable to write a zero into the box. The output won't naturally "drop out" as you say. Unfortunately your understanding of an OTE is flawed. By the way, if your user name refers to the USMC have you seen the "Offers for Veterans" page on my website?
You just have to look whether there is writing via an OTE. When the OTE is false a 0 will be written to the output , when true a one will be written to the OTE.
BUT: suppose an OTE is jumped over in the program than the output will not be rewritten. So that the status of the output will be the same as the last status.
Suppose the last time the OTE was written the output was one. And for one possible reason the OTE is not executed due to a jump in example then the output will stay on.
Misunderstanding the OTE (and any others for that matter) instruction can lead to improper programming/operation of a PLC. The common problem of treating an OTE instruction like a relay coil is briefly discussed in this video. It is equally important to understand that the OTE instruction can determine the state (1/0) of either an input or output bit/box in the processor. It took a bit for me to absorb all of this but it was extremely well done.
