Control systems, especially SW, including their installation and recovery, are provided by subcontractors. (Especially the company Dites spol.s r.o., Teplice.)
One of the company's products is a remote management system that enables remote control, program debugging, changes or software repairs.
This can to some extent guarantee immediate assistance with long-distance control problems. The condition is two-way quality access to the Internet, which is now common.
