3r3149. 3r3-31. I am engaged in the development, implementation and operation of automatic process control systems (APCS). At first he worked with SCADA-systems. Then he quickly switched to working with industrial device exchange protocols. Both self-writing drivers and setting up data collection systems. At the moment, my work is going through the atmosphere of Modbus, IEC-101/10? ORS and other protocols.

Accelerate the process of creating modbus.py.

 
Another time I want to share my experience and the results of experiments in the field of industrial automation.
 
At the moment, we have slightly changed the concept of constructing a device polling system using the python language.
 
Most modules SCADA systems are built on the principle of a bunch of "Executable file - configuration file" . here.
 
 
PS.
 
There remains one problem, the solution of which we have not yet found.
 
The running polling driver selects 100% of the processor's resources, if you start two drivers, then ...[/h]

 
 
How to ensure the functional component of safety management systems? What is the difference between functional security and information security and which of them is "more important"? Does it make sense in certification for compliance with standards? I tried to share my experience in solving these and other issues with the community when I started publishing a year and a half ago on the habr. a series of articles . During this time, from the series of articles there was something more.
 
 
The other day publishing house "Infra-Engineering" published my book ...
