Productivity 2000 PLC Ladder Logic Counter

Most programmable logic controller (PLC) programs will include a counter instruction. The Productivity 2000 Series PLC has two different counter instructions for your program. These can be used in several different ways to adapt to your application. Basically, counters are used to count up or down to a specific limit. When the limit is reached, the output is turned on. Counters can be made from a few different instructions from the PLC. The math instruction uses the one-shot (leading edge) input to add 1 to an internal register to keep track of the counter's value. A comparison is used to compare this counter value to a set value (SV). The output is turned on if it is greater than or equal. Another input is used for the reset of the counter value. Copy is used to move the reset value into the counter value. This reset will usually override the counting application. Breaking down the counter's essential operation will help us understand our application and how we can utilize counters in our automation programs. The productivity suite software has Simple Counters (SCNT) and the Counters (CNT) instructions. We will be reviewing these instructions and looking at how to implement them in our ladder logic program. Let's get started. Detailed information can be found on our website.

Here are just a few. - CPU with 5 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 so you can 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
