Accelerator Subsystems

A typical control-system architecture is shown in Figure 13.1. At the bottom we see the sensors and actuators that are connected to micro-controller or PLC systems, as discussed in the previous subsection. Power supplies or motor-controllers with built-in bus interface belong to this category as well. The controllers, in turn, communicate with control-system servers via field-buses, Ethernet or USB, as mentioned before. The servers are directly connected to a control-system network, which is usually Ethernet-based, from which the high-level clients obtain their information. In the decades before the change of the millennium, the low-level controllers were often VME computers and the servers used workstations such as VAX or Unix computers. Modern commercial systems are based on PLC systems and the WinCC software. In accelerator laboratories, a number of systems are in use, oneof which is EPICS. The latter is centered around a server which is called the input-output controller (IOC). It provides many interfaces to the lower layers with micro-controllers and PLCs, while exposing a unified interface to the higher levels of the control system.

The operator layer includes a computer supplying information to the operators and the maintainers, and it is also called HMI (human machine interface) station. In the system described in this article, the SIEMENS’s WinCC is used for the development of the monitoring system.

To verify how the OPC technology can be better applied to communication between heterogeneous devices, and devices and systems, this study uses a client written QT to read and write data from the OPC server and configures the Windows Control Center (WINCC) as the OPC server. WINCC is a process-monitoring system developed by Siemens that serves as both an OPC server and client.
