Teleassistance and remote control are becoming more and more popular, especially when the downtime cost is high, due to the need of specialistic help on how to solve failures that are not easy to find out.
The capability to grant an immediate and specialistic assistance is a must-have for automatic plant’s manufacturers, especially when they sells automations abroad.
For specialistic assistance i mean or the guy who programmed the plant, or someone who knows very good the programs and machines, and that can program themselves. In general, the engineers who write programs those machines.
Depending on the cost of downtime and distance of the manufacturer, there are some solutions that can be adopted, for example:
- Providing the source code and programming enviroment on a PC connected to the PLCs.
- Provide the machines with a teleassistance system that permit you to go online on the PLC in a safe and fast way.
Usually this solutions are not cheap, but if compared with the cost of calling a technician of the manufacturer, wait for him to come and detect the failure and wait for the time to solve the failure, you conclude that the bigger consideration is not the cost of teleassistance, but how reliable it is.
Here i post some solutions that i adopted for some plants or machines.
