ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
PLC Beginner’s Guide to PLC Programming There are many different PLC manufacturers with other hardware and software. All of the programmable logic controllers have similar basic features. Here is how I would approach learning about basic PLCs. What is a PLC? (Programmable Logic Controller) – Video Top 7 problems with beginners using ladder logic – … Read more
We will now look at the compare instructions available on the Omron CP1H controller. Just about every program usually has some data comparison instruction. This is the ability to compare information from one area of the controller to another and act on results. The Omron CP1H series of programmable logic controllers provide several different ways … Read more
The Omron CP1H series of programmable logic controllers have a fixed input and output addressing system. Every PLC has its own way of addressing its inputs and outputs. We will be looking at how the CP1H series of controller addresses its inputs and outputs. Numbering systems used in this controller will also be looked at … Read more
We will now look at the Horner XL4 numbering system and addressing. Data is stored in different memory-type locations called registers. The registers can be either bits or words (16bit). Multiple registers can be used together to store a 32-bit value. (Double word) This all in one controller has several additional registers to handle some … Read more
We will now look at the parts of a PLC system. When I was in school PLCs were just in their infancy. We were taught that the PLC consisted of the central processing unit (CPU), analog and digital inputs, and outputs. Everything was programmed with dedicated handheld devices and/or software devices on specialized hardware. We … Read more
We program the Horner XL4 OCS all-in-one controller by using Cscape. We will now use our Cscape software to establish communication. Last time we customized Cscape with icons to make it easier to find, communicate and control the unit. There are two different ways to communicate to the XL4 OCS controller, Ethernet and Serial. There … Read more
Continuing our series, we will now look at the numbering systems and addressing used in the Click PLC. Previously we have discussed: System Hardware – Video Installing the Software – Video Establish Communication – Video The programming software and manuals can be downloaded from the Automation Direct website free of charge. These are being used exclusively … Read more
So far in this series, we have discussed the Click PLC System Hardware (Video) and Installed the Software (Video). Today we will be establishing PC to PLC communications. This will allow us to program, edit or alter the way in which our Click PLC will function.
Using Visual Basic 2015, we will log three holding registers from the PLC, along with the time and date, into a Microsoft Access Database. We will log every minute to the database, including the information we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement … Read more
The SOLO Temperature Controller is a single-loop dual-output process temperature controller that can control both heating and cooling simultaneously. It is available in 1/32, 1/16, 1/8, and 1/4 DIN panel sizes and is UL, CUL, and CE-approved. There are four types of control modes: PID (Auto Tuning (AT) function) – Solo Control Modes P stands … Read more
