using C++ in machine control software

(OP)
I need any artical or paper about using C++ programming language as machine control software.
And any use for C++ prog. Lang. as an industrial control software.

RE: using C++ in machine control software

I've used C++ for partial control in locomotive control software. This was a real time embedded application- where memory and processor resources are limited.

With C++, there're some concerns being raised with respect to industrial/real time applications. Almost all these can be effectively tackled if specific design/development strategies are followed.- a simple example is freeing (deleting) an object when it's not needed anymore.

RE: using C++ in machine control software

Please give me some sample code in C++ for reading inputs through a serial port.

RE: using C++ in machine control software

Please just use inport and outport functions to figure it out, supposed you should be very clear of every bit of the instruction bytes mean for your card,plc or other devices.

RE: using C++ in machine control software

hi gkmaint,
If you just want to read in bytes from serial port (UART) then just use the function intb(), like stated by samsara. But in case of real time problem, you should capture the bytes using interrupt, so write your interrupt routine and placed it in the right adress, but you must firt save the "something" accidently in this address and put it back after your task done.

cheers

White Paper - PLM and ERP: Their Respective Roles in Modern Manufacturing
Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each person’s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
White Paper - Medical Device Design Control
Medical device product development is a highly integrated and regulated process. Implementation of a requirements tracking solution requires attention to a variety of nuanced topics. When presented with the task of tracking the many concept relationships in a project of this type, the initial software solution of choice tends to be a two-dimensional text systems. Download Now
