PMX command set (API)
486 A4354-2.2 HBM: public PMX
S Some commands may be optional, because they only
select the default. If the default has not been changed
before, they can be omitted:
pcs 0 sps 0 mss 214
S The default of the recording mask (if never set before)
is: all equipped channels (except time channel), all
their subchannels, and signal “gross” for all of them.
S A value line is also called a value page. It is a set of
values defined by the measurement rate group config
uration. For the above example, this means, the lines
have the size of two float values for each measure
ment group, because we have put two subchannels
(each has one active signal) into a group. A float value
consists of 4 bytes. Therefore the measurement val
ues will arrive as a multiple of 2 float values
(size(line)=2) or 8 bytes, respectively
S In the above example selections via pcs and sps are
done twice. That can be packed:
pcs 1 (x) sps 3,4 (x) mrg 0 (x)
pcs 2 (x) sps 1,2 (x) mrg 1 (x)
icr 6320,0 (x)
icr 6319,1 (x)
pcs 1 (x) sms 3,4 (x) sps 3,4 (x) mss 214 (x)
pcs 2 (x) sms 1,2 (x) sps 1,2 (x) mss 214 (x)
This is identical with:
pcs 1 (x) sms 3,4 (x) sps 3,4 (x) mss 214 (x) mrg 0 (x)
pcs 2 (x) sms 1,2 (x) sps 1,2 (x) mss 214 (x) mrg 1 (x)
icr 6320,0 (x)
icr 6319,1 (x)
