Hi We are trying to implement an IOC for the Libera Spark BPM using stream device, one of the tricky commands for example is TBT_IQ <N> which returns a variable-length buffer of turn-by-turn
data. An example: TBT_IQ 3 22 -36 19 -38 16 -31 -3 -31 39 -212 29 -212 26 -163 -37 -150
39 -175 36 -176 27 -133 -21 -129 As you can see the output is an array of fixed columns (IQ parameters) and variable rows (waveforms length). In a single line you can easily parse and skip any value, but in this
format we have two problems:
1.
Is it possible to parse variable number of IN commands in the protocol file?
2.
Variable "IN" commands mean variable waveform length, is this possible in EPICS? Best Regards, Abdalla Ahmad Control Engineer SESAME Allan, Jordan. Tel: (+962-5) 3511348 , ext. 265 Fax: (+962-5) 3511423 Mob: (+962-7)88183296 |
