13.1 Parameterising analog modules
13.1.1 Parameter data
( 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.
l For a 4×analog input module, 10 bytes of parameter data are available. The
following are defined via the parameter data
The signal function for each input (current measurement, voltage
measurement, temperature measurement etc.),
The module error behavior,
The conversion speed.
l The module can be parameterised with the configuration tool or via slot and
index.
To set the parameters via slot and index, the function blocks SFB 52 (read)
and SFB 53 (write) are required.
