The modified GMOS assemblyControl record used by the NAOMI project

For details of the device support code written for different assemblies, the reader is referred to the source code, documentation on the source code (which describes the pickoff assembly code in some detail), and the documentation for each assembly DM screen. Changes to the assemblyControl record implemented for NAOMI fall into the following categories:

• Minor bug fixes
• Changes to the handling of special processing which occurs, for instance, when an attached device changes busy state. Mods were made to the special() record support function.
• New input fields were added. The GMOS record has five input fields, A-E. The NAOMI record has ten, A-J.
• Five extra inlinks were added, to enable the assembly to examine the MPOS field of attached devices. This is essential in the pickoff assembly, where the current configuration of the instrument determines which velocities must be used to achieve a new configuration.
• Initialisation of the input links for the record was modified, due to the changes above.
• A new mode, JOG, was added to the record. This enables the record to effectively handle JOG operations with its attached devices. This required the addition of a new device support function, jogMode().
• The GMOS team subsequently implemented further modifications to the record, including the addition of a device support function for fault (interlock) handling, that were not implemented for NAOMI.
