ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
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
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
We will be installing a USB to rs485 installation on our computer. The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular … Read more
We will be creating an HMI (human machine interface) login screen for the cylinder program that we developed previously. BUILDING A PLC PROGRAM THAT YOU CAN BE PROUD OF – PART 6 Our program had a Run, Jog and Teach mode for the cylinders. Our user will login with a user name and password. Based … Read more
Master cylinder control with programmable 500-step sequences! Learn to build a 7-cylinder sequencer using AdvancedHMI and Modbus TCP. Full tutorial included. We will continue the series by looking at a sequencer controlling seven cylinders that can be taught. The cylinders can be programmed by the operator from the AdvancedHMI screen. You will be able to … Read more
We will now look at the Game of Simon for our part 5 in this series of building a PLC program. Learning all about bit manipulation and sequencers Simon is a memory game introduced in 1978. It has four colored buttons, each producing a particular tone when it is pressed or activated by the device. … Read more
We will now create a PLC with HMI Training and learning environment. We will use the Automation Direct Do-More programming software tied into the Advanced HMI learning package via Modbus TCP. All of the software is free and fully functional. Learn PLC programming and use a powerful HMI (Human Machine Interface) easily and freely. Setting … Read more
We are using Modbus TCP protocol, reading ten registers in the PLC, and displaying a bar graph in Excel. e will use Visual Basic for Applications (VBA) to communicate with a PLC. Previously we have used VB6 to communicate Modbus TCP. Sequence for Modbus TCP on Excel using VBA The following steps will be done: … Read more
Utilizing the CX Server DDE Manager will allow us to provide a link to the information in the Omron PLC. This link can be placed on an Excel spreadsheet. Charts, graphs, etc., can be made from the data. We will create links on an excel spreadsheet from a CQM1H and a CP1L PLC. The information … Read more
