FBD Function Block PLC controller, new and ladder diagram graphical plc similar source code

ISCADAPLC Development environment and operating environment

• Overview

The control algorithm is encapsulated by the IEC FBD61499 function Block method, the control strategy configuration can be completed by user dragging and connecting, online simulation, single step debugging, and the configuration control strategy algorithm can be compiled into two object codes, in which the intermediate code can be used for simulation debugging and PLC The run environment interprets execution, while the embedded code can be interpreted in the embedded device execution (via the embedded FBD interpreter), thus forming a complete PLC programmable control system solution.

Second, the function

1, graphical configuration control strategy, easy to use

2, rich function block algorithm, mathematics, logic, timer, counter, Advanced PID , etc.

3, expression input function, the input expression can participate in the operation, powerful

4,IO device driver connection function, configurable device io parameters, after connecting the device, in-line emulation, with OPC interface, user-defined driver, and virtual drive 3 ways

5, on-line simulation function and single-step debugging function, can walk alone, debugging control strategy.

6, theFBD Control Strategy algorithm optimization function, can be the function block execution order adjustment, user optimization.

7, compiled into a separate target code, intermediate code and Embedded code, can be interpreted by the PC and embedded equipment implementation, the formation of an independent PLC control system.

8, under the PC is the soft PLC, can connect the device driver to complete automatic control.
