Stop!
The modules are not protected against wrong parameter settings
by the hardware. They will be destroyed if the signals or encoders
connected do not match the measuring range set:
l Max. 15 V input voltage in the voltage measuring range.
l No input voltage in the resistance measuring range.
l When the measuring range is changed, only assign the inputs
after the first gateway initialisation has been completed:
– During initialisation, the previous settings are still active.
Unsuitable input circuits may destroy the modules. Changes
will only become effective and are permanently saved after
initialisation.
For the 4xanalog input, 10 bytes of parameter data are available which are
assigned via SDOs. The following can be defined via the parameter data:
l The signal function for each input (current measurement, voltage
measurement, temperature measurement etc.),
l The module error behaviour,
l The conversion speed.
Parameter setting via Global Drive Control (GDC):
Depending on the plug−in station, the module is activated via the indices
I3001
h
... I3010
h
(max. 16 analog modules). The parameter data are assigned in
the subindex 1 ... 3.
Parameter setting via CoDeSys:
The max. 16 analog modules are addressed via index I3401
h
. The parameter data
are assigned in the subindices 1 ... 64 (4 bytes per subindex). The module
4xanalog input assigns 3 subindices.
