What is Px Developer?

Px Developer is a software product developed by Mitsubishi Electric Corporation that consists of a programming tool and a monitoring tool that support users to process DDC on QnP(R)HCPUs. DDC is a method of controlling complex systems by dividing them into smaller subsystems that can be controlled independently by local controllers. DDC is widely used in various industries such as chemical, petrochemical, power generation, water treatment, HVAC, and building automation.

The programming tool of Px Developer allows users to create and edit FBD (function block diagram) programs that describe the logic and behavior of each subsystem. FBD is a graphical language that complies with the IEC 61131-3 standard and is easy to understand and use. The monitoring tool of Px Developer allows users to monitor and tune the DDC processes using tag data, face plates, tuning trends, alarms, event lists, and other screens. The monitoring tool also supports auto tuning by the step response method or the limit cycle method.

Features and benefits of Px Developer

Px Developer has many features and benefits that make it a superior software for DDC processing. Some of them are:

  • Substantial FBs (function blocks) and functions for loop control. Px Developer has various FBs and functions that are designed for loop control applications such as PID control, cascade control, feedforward control, ratio control, etc. These FBs and functions can be easily combined and customized to suit different DDC scenarios.

  • Easy to standardize and reuse programs. Px Developer complies with the IEC 61131-3 standards and allows users to modularize their programs by creating custom FBs. This enables users to reuse their programs in future projects that require similar capabilities, reducing development time and improving quality.

  • Integration with sequence control programs. Px Developer can exchange data with ladder programs (created with GX Developer) using logical names (labels) instead of device memory addresses. This makes it easy to change constants of loop control tags, SV values, etc. from the ladder programs.

  • Comprehensive tuning and monitoring functions. Px Developer has various screens that can be used to tune, monitor, and operate the created control loops. Users can also perform auto tuning by selecting the appropriate method and parameters.

  • Improved operability for redundant system. Px Developer supports designing redundant systems without repeating the same procedure for the control and standby systems, reducing the total setup and design time.
