Abstract

The vacuum gauge control system has been designed and implemented using multi-serial communication controllers (MSCC) for the 2.5 Gev storage ring at the Pohang Accelerator Laboratory (PAL). There are 20 Balzers vacuum gauges and 17 Granville-Phillips vacuum gauges at the storage ring. A MSCC have two RS485 (max speed 460.8Kbps) field network port, 8 channel serial communication ports (max speed 460.8Kbps) connected to gauge controller for serial communication control. 12 MSCCs are connected to a personal computer (PC) through the RS485 field network. The PC can automatically control the MSCCs by sending set of commands through the network. The commands specify the duration of the MODBUS protocol. Upon receiving a command from a PC running under Windows2000 through the network, the MSCC communicate through the serial output ports to gauge controller. In this paper, we describe control structure and scheme of the vacuum gauge control system.
