Gensub record epics. Thanks to Eric Norum for detailing the required changes.
Gensub record epics. The genSub record was deleted from our version many years ago after the aSub was added to Base. Also, TMOD needs to be given value "Write" In the "receiving" database, a single 'genSub' record gets the values via Channel Access There is a Message Button in the edm program which is used to trigger processing of the genSub record, When genSub is processed it takes the values from all the other records, performs some calculations, creates a string of numeric values and prints the results. the data, which consists of 10 to 15 bytes of numbers (some zero) is constructed in the process subroutine of a genSub record.

The genSub EPICS record was written to provide a general, flexible method to call a C subroutine from an EPICS record, without the limitations of the original EPICS subroutine record. Trying to access it by name results in a dbNameToAddr failure.

I made experimental changes to the latest version 1-4 so that asynch processing is recognized. db at master · slac-epics/genSub Navigate by Date: Prev: VxWorks Billy R. The controls of the hardware has been realized with a genSub record for the CCD detector and a stream device for the motion of the LTP head.

This is what I am worried about. The advantage of using arrays when transferring data between IOCs, rather than a set of values from individual records, is that Channel Access guarantees to Using EPICS for Beamline Control and Data Acquisition. > > I have localized the problem to an unfortunate interaction between schedit > and e2db. It allows the easy passage of arrays, scalars and user defined structures between records existing within the same database and between those which exist in separate IOC’s. The record is getting processed and my init and process routines are getting called correctly, but the record does not appear in the list of records produced by dbl. The advantage of using arrays when transferring data between IOC’s, rather The data acquisition is implemented as four-dimensional scan using the standard EPICS sscan record. On the second link is a user defined structure (defined in pinfo.

These are mostly longin, one ot two bo and mbbo, and one genSub. It allows the easy passage of arrays, scalars and user defined structures between records existing within the same database and between those which exist in separate These files are meant to provide an example of how to use the 'genSub' record. 1 Introduction This record, known as ‘genSub’, has been designed as an enhancement to the standard EPICS subroutine record. Somehow, the data and the number bytes need to be transferred to the BOUT and NOWT fields of the asyn record. I have successfully put together a soft IOC which consists of a number "Soft Channel" type of records. 1. You'll have to get the genSub record to write to a record that can have device support, such as an ao record. EPICS genSub record. In the "sending" database, a genSub record puts out values on 4 links. 3 which you can now download from here.

I am NOT suggesting that the genSub tar ball be modified in this way since it would probably break a fair amount of existing code developed on Unix platforms, but other EPICS programmers working on Windows platforms may find the record more useful knowing about this simple fix. genSub: Mirror for /afs/slac/g/cd/swe/git/repos/package/epics/modules/genSub. spectrum Calculate the one-dimensional FFT of a waveform. 1 Purpose This document describes the EPICS records created by the Gemini 8M Telescopes Project for use in its telescope and instrument control databases. Record Types Included genSub Generic subroutine support. Acknowledgements. Anybody want to > hazard a guess The record simply lacks the code required to use device support. The record simply lacks the code required to use device support. The genSub record fits only very loosely into the 'waveform processing' classification, but provides very useful functionality and deserves to be widely distributed. 8 > I'm trying to use genSub record v1-6 I found in synApps 5-1 under EPICS > 3.

In the edm companion for this IOC, I have a number of text controls to put new values into all the records with the exception of the genSub record. h).

Ready to use with StreamDevice, the driver uses the open-source libssh2 library to handle the secure SSH-2 protocol.
