Thank you for another click plc video. Is there any special reason why you chose the sourcing wiring? Almost everything I have ever worked on uses the Sinking method. Until I started messing around with PLC's I never used sourcing. (SLC 500 has sourcing only input card)
Hi Osseo, Thanks for the comments. There is no special reason that I chose sourcing (positive switching) wiring. Lots of debate has been done on the advantages of one over another but it just boils down to where the installation is located and what they want to see in the control circuit. Regards, Garry
Excellent video and explanation. Thank you. It took me 10 minutes to figure out why rung 1 Stop Pushbutton NO contact X002 is blue (passing) when you brought up the programming software at 4:00 minutes. Then I finally realized the Stop PB real contact is NC so the logic contact changed its state and is bit 1. Just my story with this lesson. But excellent explanation of the wiring for this PB station.
do you have a video on wiring the banner OTBVP6QD OPTICAL start switches. I need to see how to wire two as a safety measure for starting a press operation using two pneumatic air cylinders. one to press down and a second one to locate the part.
Hi Rod, You would need a Two-Hand Safety Control Relay in a press application like this one. Here is a link to the safety relay. www.automationdirect.com/adc/shopping/catalog/safety/safety_relay_modules/two-hand_safety_control_relays#start=0 You will find typical wiring diagrams for these relays in the specifications. If your logic is different than this, a possible solution would be a safety controller. Typical safety controllers will monitor the input and output contacts to ensure the signals work. accautomation.ca/series/mosaic-modular-safety-integrated-controller/ I hope this helps you out. Regards, Garry
@@schoonymopar When looking at safety items, this is relatively less expensive. If this is for learning purposes only, then I would just create a program that would do the same as the safety circuit. Regards, Garry
Hey man, just wondering of you used a separate power source for your light and your push buttons or if you powered everything using the power supply attached to the plc?
Hi Ben, Depending on if your common on your PLC is +24VDC or 0VDC would depend on the wiring to the PLC. This is usually determined by the additional sensors like NPN or PNP. I have not provided a diagram here because this is just in series with the input. Here is a post that will show you some wiring diagrams for pushbuttons and relays. accautomation.ca/wiring-3-wire-dc-npn-and-pnp-sensors/ accautomation.ca/heres-a-quick-way-to-wire-npn-and-pnp-devices/ I hope this helps you out. Regards, Garry
This is a newbie programming question for sure and hope you don't mind helping me understand something. What are the control relay contacts (C-1, C-2) and so on that you have in parallel with your inputs being used for? I assume they are internal and simply curious as to what actuates them and when do they actuate. Any help to understand this would be greatly appreciated. By the way, great video! I just subscribed and I will be checking out your other content.
Hi JP, Thanks for the comments. You are correct. C1 and C2 are internal bits of the PLC. These are activated by the drum instruction in the PLC. accautomation.ca/click-plc-drum-instruction/ The above link will take you to the post explaining the drum instruction on the Click PLC. Here is a link to the entire Click PLC Series. accautomation.ca/series/click-plc/ Note: Videos are associated with each post for further explanation. Since you indicated that you are new to programming PLCs, I would recommend you check out beginner's guide. You can go through this at your own pace, skipping the parts that you already know. accautomation.ca/programming/plc-beginners-guide/ I hope this will help you out. Let me know if you have any questions. Thank you, Garry
@@ACCautomation thank you for the follow up and links. I'm very proficient in wiring schematics, relay logic, and most other passive devices. I've modified several different integrated controls systems to perform new tasks or provide newer features for specific code compliancy within my industry. Most of these systems include outdated or older PLC controls that are no longer supported. The circuitry I have implemented is done by using the existing input and output configurations but having to add a shit ton of relay logic to achieve the outcome I need. So all of the information you have provided is seriously appreciated. I'm trying to simplify things and programming seems to be my only real solution. Thanks again!

Hi Chris, The switch that is being wired up is sometimes referred to as an HOA.

Hi Dino77 Mullen,
Thanks for the comments. The NC contact can trip you up. It has happened to all of us.

Hi Jaaved Mohamed,
In this video, all of the power was supplied by the 24VDC supply attached to the PLC.

can you provide wiring schematics? you mentioned using C1 as a common 24V+
