Productivity 1000 Series PLC PID Ramp Soak

Productivity PLC – PID Ramp Soak Instruction The purpose of a ramp soak instruction is to make gradual, controlled changes in temperature (Ramp), followed by a temperature hold (Soak) period. We will be using our Proportional-Integral-Derivative PID Instruction that we looked at last time to apply the ramp/soak instruction. Using the immersion heater in a … Read more

Productivity 1000 Series PLC PID Instruction

PID Loop (PID) Instruction (Auto Tuning) – Productivity 1000 PLC A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the Error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the … Read more

Productivity 1000 Series PLC Firmware Update

Firmware is usually PLC operating system code that is written into a read-only memory. The BIOS (Basic Input Output System) of a PC (personal computer) is a good example of firmware. It provides a low-level interface between the hardware and software. The firmware for the productivity series of PLCs must be downloaded separately from the … Read more

Productivity 1000 Series PLC Modbus RTU Serial

The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with either the RS232 or RS485 ports on this PLC. Modbus RTU is an open (published) protocol that uses the Master / Slave architecture. It’s a … Read more

Productivity 1000 Series PLC Web Server

The productivity series of PLCs has a built-in web server. This web server function can make a non-secure (HTTP) connection to the CPU. This is done with your browser. You can then view read-only system tags and open, save or delete files stored on the micro SD drive. Previously we stored data logged files on … Read more

Productivity 1000 Series PLC Data Logger

The productivity series of PLCs has a built in data logger. This easy data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of … Read more
