The OPC readout via MBS
MBS can read some OPC data containing information about the status of some ELBE parameters. This is done using a shared memory. This shared memory is allocated and written by the program opc2shm which can be found on the MBS working directory ("mbsrun/nng/"). The source code can be found in "urania:/home/ntofdaq/c/shmem/".
This program has to be started from one of the power PCs rio3 or rio6 (using ./opc2shm). By setting the "opcreadout(1)" value in the corresponding "setup_vme_1.ini(2)" the OPC data will be read from the shared memory into the data stream, i.e., the listmode file.
