Cloud process control system

Smaller automation systems such as drinking water supplies and sewage treatment plants are often not permanently manned, but are supervised by operating personnel from other plants or by municipal administrators.
Operators often look for a possible remote control to get a quick and easy overview of the running process or to be able to change individual parameters without having to go there every time.
A web-based process control system (PCS) is the best solution in terms of comfort and safety, but it should also be affordable in terms of purchase and maintenance. Expensive investments or the maintenance of an own server infrastructure is out of the question for operators for cost reasons. A licence for an online solution with a PLS in the cloud is therefore of great interest.
