Each poll ed device responds by sending a Status Byte which indicates among other things whether or not the device requested service Serial Polling and Status Byte Messages are fully explained in the discussion of the Status Byte Message see Paragraph 3 142 Status Byte The Require Service Message will be cleared when the device sending it is polled or the condition causing it disappears In some applications the controller is programmed to interrupt its main pro gram and respond to a Require Service Message immediately In other applications it may periodically check the status of the Service Request Line and respond when a request is discovered 3 141 Implementation The Require Service Message originates in the devices on the bus A technical description of its implementation is presented in Figure 3 A 10 of Appendix A 3 142 Status Byte A Status Byte Message is sent by a device on the bus to the active con troller The individual bits of the Status Byte indicate the status of various instrument func tions and whether the instrument requested service Once the Status Byte of an instrument is in the controller the status of the instrument functions may be determined by examining the truth state of each bit The controller can be programmed to take the appropriate action bas ed upon the functional status of the bus instruments For example if bit 6 of the hp 3336 Model 3336A B C 8 Model 3336A B C Status Byte

ATUS BIT The Data Message implements the primary purpose of the HP IB It is used to send the codes that activate instrument functions and transfer measurement data from one device to another This message is subdivided into Data Send and Data Receive for operator conve nience Technically there is no difference between Data Messages used to send and receive information The Trigger Message causes simultaneous action in two or more devices on the bus The action executed depends upon the design of the particular instrument The hp 3336 does not respond to the Trigger Message The remaining ten Bus Messages are used to manage the system Their only purpose is to facilitate the implementation of the Data Trigger Messages 3 122 Implementing Bus Messages Recall that the objective is to answer the question What instructions must be entered on the controller to cause a particular action in the instrument This question is answered by converting the Bus Messages into controller statements that cause the desired action in the instrument when executed by the controller Since these twelve messages describe every possible HP IB operation converting them to controller statements will enable the operator to implement every possible HP IB operation A pro cedure for converting the Bus Messages to controller statements follows NOTE If the controller used in your system is a hp 9825A Desktop Computer substitute the appropriate Bus Message Im
