( 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.
