To store data you have two choices of operation 1 Mark files on the tape and then store data into the premarked files 2 Store data into non premarked files NO POSITIONED OK POSITION TAPE The tape should be positioned by Executing a RW command to mark at the beginning of a tape 2 Executing a FE command to preserve data recorded on a tape Marking files or records results in an EVD mark being placed on the tape after the command is executed This means if you remark a file located between files tape is positioned with an FF command all remaining files are inaccessible For example if you had this structure on tape fF File File File File File EVD 1 2 3 4 5 n Mark jf f j i and remarked File 2 the new structure would be with the contents of Files 3 through n being lost If an error occurs front panel lamp is flashing data input and output stops The CTU responds only to an OE or OS command Errors can be detected by interrupt service routines or by periodic polling of the CTU If your controller does not handle interrupts then you may have to perform polling your bus frequently through a program to determine when an error occurs RETURN Errors are cleared by any of these three commands 1 OS 2 OE 3 Device Clear The OS command allows the CTU to return to normal operation The error codes are not returned from the CTU The error cod

12. The HP Interface Bus HP IB is Hewlett Packard s implementation of the IEEE standard 488 1975 The HP IB provides an interconnecting channel for data transfer between devices on the HP IB The following is a definition of the terms and concepts used to describe HP IB bus system operations HP IB System Terms 1 Addressing The characters sent by a controlling device specifying which device sends information on the bus and which device s receives that information 2 Byte A unit of information consisting of 8 binary digits bits 3 Device Any unit that is compatible with the IEEE Standard 488 1975 4 Device Dependent A response to information sent on the HP IB that is characteristic of an individual device s design and may vary from device to device 5 Operator The person that operates either the system or any device in the system 6 Polling The process typically used by a controller to locate a device that needs to interact with the controller There are two types of polling e Serial Poll This method obtains one byte of operational information about an indi vidual device in the system The process must be repeated for each device from which information is desired e Parallel Poll This method obtains information about a group of devices simultane ously Interface Bus Concepts Devices which communicate along the interface bus can be classified into three basic categories 1 Talker
