Technical support / Assistance Needed
« on: May 03, 2012, 05:51:31 AM »
How would I program a PLC to do the following:
? Proximity switch is normally off ? it is clicked on ? it then sends a signal to my PLC ? I want to capture that signal as data for my base server PC ? then I want to output that signal to an LED light to light up, every time the proximity sensor goes ON.
? Now part 2. I want 12 proximity sensors set to light up one LED light, and still want to capture the data from each INDIVIDUAL proximity sensor. (Prox 1 was clicked 423 times, Prox 2 was clicked 124 times, Prox 3 was clicked 0 times, etc)
? Now Part 3. I want to have one proximity sensor just collecting data ? no outputs, just data collection - and output only to a webpage.
? Now Part 4. I havea sensor to measure distance, relay that to my PLC ? just for data collection ? and output only to a webpage.
That is the 4 different ways I need to use my PLC ? Inputs & Outputs (all digital I/O) ? and instead of an LED light, that signal is just used to count up on an LED Numerical Display.
That is the main thing here. I need to collect the data from each individual proximity switch because each one of those proximity switches are actually different paint colors or different spray guns that we use. Hope this makes it easier to understand. I apologize again for my inexperience.

I am currently a cost accountant at a Fiberglass Company in Northern Indiana, and am attempting to create a counter system for our company.
I have 2 FMD1616-10 PLC's with the extesions up to 40 I/O. 1 FMD88-10 PLC...
I have plenty of wiring, digital LCD counters, proximity switches (NPN), power supplies, etc. I am fine on the hardware side of the project, but I am lost when it comes to Ladder+ Logic programming.
Simply what I want to do is have 40 proximity switches feeding into the PLC Digital Inputs and have those 40 PLC inputs feed back to my main PC via the ethernet connection on the board, in other words, monitor what information those inputs are receiving. Then I want to have the digital outputs only read out to a minimal number of LCD displays. (Per PLC) - meaning I don't want to have 40 inputs to 40 outputs (from the PLC), because my LCD display cannot accept more than 2 inputs.
What I mean by the minimal number of LCD displays is this:
I have a paint pump at my company, within each paint booth I want to put 1 LCD display so the painter can see how many strokes he is using on his part. But within that paint booth, there are up to 12 different paint pumps (that will have proximity switches counting the strokes). I would like to have those 12 proximity switches feeding into my digital inputs on my PLC, and have only 1 digital output for that LCD display. And it's a Digital display that only accepts signals for counts.
Hope this makes more sense...sorry new to all this.
Expanded:
Digital plc input #1 prox to digital PLC output #1 which will go to my LCD monitor
Digital plc input #2 prox to digital PLC output #2 which will go to my LCD monitor
Digital plc input #4 prox to digital PLC output #3 which will go to my LCD monitor
Digital Inputs on PLC 7-18 are from Proximity Switches
I want those to go to Digital PLC Output #4 which will go to my LCD monitor
Digital Inputs on PLC 19-24 are from Proximity Switches
I want those to go to Digital PLC Output #5 which will go to my LCD monitor
***and that is just 1/2 of all my PLC inputs, but I figure, if I can get the big ones, the rest will just flow easy. ***Attached is my architecture for my PLC's
