  • Control systems
  • PLC control units

product description

Remote maintenance access for support and optimisation is often necessary for operating an automation system. In order to authorise controlled and secure remote access for wks group employees to customer systems, wks group has set up a remote maintenance centre at its company headquarters. If required and approved, this centre allows remote access to control systems, control units (PLCs) and other network devices in the customer network. In order that the employee can access the system during a service/support call, the customer must set up a communication connection (VPN tunnel) to the remote maintenance centre.

The employee performing the support/optimisation task also dials into the remote maintenance centre and connects to the plant´s system. This allows the employee to carry out the work securely and in a locationindependent manner.
