【 摘 要 】

The control of GPIB devices at Jefferson Lab is based on the GPIB device/driver library. The library is a part of the device/driver development framework. It is activated with the use of the device configuration files that define all hardware components used in the control system to communicate with GPIB devices. As soon as the software is activated, it is ready to handle any device connected to these components and only needs to know the set of commands that the device can understand. The old GPIB control software at Jefferson Lab requires the definition of these commands in the form of a device control software module written in C for each device. Though such modules are relatively simple, they have to be created, successfully compiled, and supported for all control computer platforms. In the new version of GPIB control software all device communication commands are defined in device protocol (ASCII text) files. This makes the support of GPIB devices in the control system much easier.
