Parameter description
P338 AO state
Display of internal function module state.
P337 AO test value
The analog output (DA converter) can be tested via this parameter.
e.g. AO 1 source Pxxx P330 = 337
AO test value P337 = +10 → analog output 1 = + 10 V
AO 1 scaling P332 = -2000 → analog output 1 = - 5 V
AO offset channel 1 P331 = 14000 → analog output 1 = + 2 V
P330 AO 1 source Pxxx
P334 AO 2 source Pxxx
The output parameter numbers are entered here.
The respective channel is switched off, if this parameter is equal 0.
If a 32 bit parameter is programmed on one channel, the low word of this parameter is trans-
mitted. To transmit the high word, both channels (P330 and P334) must be programmed to
the same parameter. As a result channel 1 transmits the low word and channel 2 the high
word of the 32 bit parameter. Is channel 1 programmed to another parameter then channel 2
transmits the low word. That means that the high word of a parameter can´t be transmitted
separately without the low word. Channel 1 transmits always the low word and channel 2
transmits always the high word.
P331 AO 1 offset
P335 AO 2 offset
The offset of the analog outputs is set here.
P332 AO 1 scaling
P336 AO 2 scaling
A scaling factor can also be selected for optimum parameter output. The respective channel
is switched off, if this parameter is equal 0.
Bit no. Meaning
0 0: STOP, analog output 1 switched off
1: RUN, analog output 1 is active
1 ... 3 reserved
4 analog output 1 at negative threshold (-10V) (X26:7)
5 analog output 1 at positive threshold (+10V) (X26:7)
8 0: STOP, analog output 2 switched off
1: RUN, analog output 2 is active
9...11 reserved
12 analog output 2 at negative threshold (-10V) (X26:8)
13 analog output 2 at positive threshold (+10V) (X26:8)
