ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
We will look at a PLC programming example of delaying the start of 7 motors. Each motor will be on a switch that the operator can select at any time. The motor outputs should have a 5-second delay between the outputs coming on. This question originally came from PLCTalk.net. An original solution to the problem … Read more
Continuing our series, we will now look at timers and counters and how they are used in the Click PLC. Previously we have discussed: System Hardware – Video Installing the Software – Video Establish Communication – Video Numbering System and Addressing – Video The programming software and manuals can be downloaded from the Automation Direct website … 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.
Previously we discussed the Click PLC System Hardware – Video. Today we will be installing the free software required to program the PLC. This includes the actual program and communication drivers. The current version of the Click Software programming package can be downloaded here. Installation of this package is similar to the instructions below.
Many people ask me what I do when looking at a new PLC model or system. My approach is very straight forward and we will view this in action with this Click PLC series. This series will go from examining the hardware to programming and communicating to the PLC in several ways. If you have … Read more
We will be looking at and explaining IP Addressing, MAC Addressing (Physical Address), Subnets, and Subnet Masks. Communication using Ethernet usually revolves around the Open Systems Interconnection model (OSI model). This model was made for computing systems to communicate without regard for the underlying internal structure and technology. IP Addressing Analogy Think of it like … Read more
Deploying an AdvancedHMI project on the industrial floor sounds like an easy task, but there are a few things that you should consider. The HMI (Human Machine Interface) user interface will run on a computer. The industrial environment is one in which temperature, dust, electrical noise, etc. are always present. This can also be combined … Read more
Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in … Read more
Modbus RTU will be the serial (RS485) method in which we will communicate between the AdvancedHMI Screen and the Automation Direct Solo Process Temperature Controller. We can address up to 247 (Solo 1 to 247) devices on this master-slave protocol. A maximum of 32 devices (Nodes) on the network can communicate to the master. A … Read more
