Productivity 2000 Series PLC - Automation Direct - Productivity 2000 PLC Node-RED Modbus TCP

We will now look at communication between the Productivity 2000 PLC (Modbus TCP Server) and Node-RED (Modbus TCP Client). Node-RED is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that uses flow programming. Minimal coding is required; you can see the program flow visually. The best thing is that the software is free. We will look at using Node-RED with the Productivity 2000 Series PLC. Node-RED will be used to create a single Modbus flow. We will communicate to our XY-MD02 Temperature and Humidity sensor using Modbus RTU on a serial RS485 network. The present values of the sensor will be read. These values will then be written to our Productivity 2000 PLC using an Ethernet Modbus TCP network. These temperature and humidity readings will then be displayed on the P2000 CPU. Let's get started using Node-RED for Modbus communication. Detailed information can be found on our website.

Here are just a few. - CPU with five communication ports - 50MB user memory - Can handle very complex applications easily. - Limitless PID – Autotuning – Individual or Cascade Mode - etc - OLED message display on the CPU module - Plenty of discrete and analog I/O modules - Status displays on all discrete I/O modules - I/O Modules have QR codes. This can be scanned to have the latest specifications/wiring diagrams for the module. - OLED data display on analog modules - P2-RS remote I/O expansion module, or use the Productivity1000 P1-RX remote expansion module to add even lower-cost remote I/O to your system - FREE full-featured Productivity Suite software - Programming with several ports - USB, Ethernet, Serial - Hardware auto-discovery - Hot-swappable I/O - Remove cards with power on the system - Choose from three wiring options - Slim DIN rail density form factor: - hardware - power supply, CPU, and seven modules in only 10-1/2 inches - All project files (program, tag name database, and all the program documentation) in the CPU - Run-time editing and debug mode on CPU - Easy data logging with micro SD on CPU - Secure Web server to access data files and system tags - Easy drive and motion controller integration - Coordinate motion control with PS-AMC allows control of up to 16 axes and synchronization of up to 4 axes - Two-Year Warranty The Productivity 2000 series of programmable logic controllers currently has all of these features built into the P2-550 CPU. This CPU (Central Processing Unit) is also known as PAC (Programmable Automation Controller) because of its communication capabilities. ACC Automation https://www.accautomation.ca
