Practical Tips and Techniques
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
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
