Mode of operation The device requiring immediate processing e g in the case of measured value overshoot requests an SRQ On receiving this request the controller interrupts the action currently in progress and identifies by means of a serial or parallel poll the device which has requested the SRQ This device is then requested to deliver its data or give the reason for the Service Request In an IEEE bus system a theoretical maximum of 14 devices can request a Service Request at the same time The controller must then identify the requesting device by sequential serial poll In a parallel poll eight devices can be polled simultaneously In contrast to a parallel poll in a serial poll the reason for the SRQ can also be transmitted Operation with computer or terminal IEEE 488 78 parallel interface gt Service Request D 5 3 1 Serial poll SPOLL If a Service Request occurs during a measurement by initiating a serial poll the computer can identify the device which has caused the interrupt The computer must address all devices and query the status value By this means the computer can also determine the cause of the interrupt A serial poll takes longer than a parallel poll For a device to be able to respond in a serial poll the SR interface function must have been provided for in it It must also be able to function as talker and decoding of the two interface commands SPE and SPD must be possible If the controller h
