Polling HP-IB Devices

Polling HP-IB Devices

Parallel poll is the fastest means of gathering device status when several devices are connected to the bus. Each device (with this capability) can be programmed to respond with one bit of status when parallel polled. This makes it possible to obtain the status of several devices in one operation. If a device responds affirmatively to a parallel poll, more information about its specific status can be obtained by conducting a serial poll of the device.

Configuring Parallel Poll Responses

Certain devices, including the HP 16500C Logic Analysis System, can be remotely programmed by a controller to respond to a parallel poll. A device which is currently configured for a parallel poll responds to the poll by placing its current status on one of the bus data lines. The response and the data-bit number can then be programmed by the PPC (parallel poll configure) statement. No multiple listeners can be specified in this statement. If more than one device is to respond on a single bit, each device must be configured with a separate PPC statement.
