Hybrid Simulation in Virtual Prototyping of Cyclotron
Virtual Prototyping of Cyclotrons is a novel

engineering method based on CAD/CAE,
system simulation and virtual reality technology.
Virtual control is one of important component in VP, which takes roles of modeling, simulation and validation
of control system. This paper introduces a hybrid approach to build discrete system and continuous system in an
integrated model. Finite State Machine (FSM) containing continuous part was used to describe the hybrid model.
HMI and the communication between control model and other external components of VP are also discussed. This
method aims at shortening the design process and providing more support to the optimization of the prototype.

As high frequency switching solid state devices
are replacing tube devices and linear
devices, power systems become more compact
and modular. In those systems, it is
desirable to have a high quality and multi-function control board per each power system module. In order to
maintain reliable operation of the power system module, the control board requires having multiple and complex
functions. Moreover, the control board needs to be compact and low power consuming. It also needs to have a
fast communication with the main control station. However, there is no such control board available commercially.
Therefore, a general purpose power system control board (PSCB) has been under development since 2005 as a collaboration
effort between PAL and SLAC. The PSCB is an embedded, interlock supervisory, diagnostic, timing, and
set-point control board. It is designed to use in various power systems such as sequenced kicker pulsers, solid state
RF modulators, simple DC magnet power supplies, etc. The PSCB has the Ethernet communication with the TCP/IP
Modbus protocol. This paper will describe detail functions and preliminary test results of the PSCB.
Development of Machine Interlock System HMI for PLS
The Machine Interlock System (MIS) for the

Pohang Light Source (PLS) is used for the
monitoring and control of machine devices
and equipments for operation and maintenance, and protects machine devices and equipments by interlock chain
program at fault status. The MIS consists of one central system unit and seven remote local system units, and is
implemented mainly using GE-FANUC’s Programmable Logic Controller (PLC). Using information and data in the
MIS, a human-machine interface (HMI) for the MIS is developed for the operator and system manager to efficiently
control and monitor the MIS and also to log various event, trip, fault data automatically. Wonder’s FactorySuite is
used for the HMI development software. The HMI is developed under PC environments, which communicates with
the MIS through RS-485 serial link.
