Click PLC Counter Programming Example

We will now look at a programming example of a click plc counter. Programming counters in the click plc will be demonstrated through a ladder logic example.
More information can be obtained on our website. This includes all of the links mentioned in this video.

Previously we discussed:
Click PLC System-Hardware.
Click PLC Installing the Software
Click PLC Establish Communication
Click PLC Numbering System and Addressing

Continuing our series, we will now look at timers and how they are used in the Click PLC.

There are several reasons why we are using the Click PLC. Here are just a few.
- Investment is low for the hardware and the software is free
- Standalone PLC with built-in I/O
- Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc.
- Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.

Great - perfectly answered my question. Thank you.

[Mahesh-bolv]

Thanks very much. The way you explain things is the best that I have found so far.

Can we save the Count Value after power off and power on again. Retentive value has been restored to last value counted too.

The SC7 second contact is a good feature to have instead of having to use a timer. My AB trainer software for the Micrologix 1000 doesn't have this.

Is there a way to program this to display a count and a hourly average of product? Using 1 display going back and forth every few seconds?

What happens when the X001 input goes off and possibly back on later?
Is the counter 'retentive', ie.  does it retain its accumulated count?

Also, what happens if the X001 input is on for a long time - will the accumulated counter value overflow possibly going back through 0, or setting a system error that could cause issues?

I have the same questions for the timer example but that could be addressed there.

Thanks

The cotton mouth clicking sound is hugely distracting
