463 Analog Input Module
The various measuring ranges of the 463 analog input module are defined with jumpers.
Setting the data format for the 4 to 20 mA range
When using the 4 to 20 mA inputs, press the relevant switch to select between a resolution of 0 to
1023 units or 256 to 1279 units. Different data formats can be selected for all four input channels.
The relevant switches remain at the off position when using the following inputs
•
0 to 1 V
•
0 to 10 V
•
0 to 20 mA.

Address setting
The 463 analog input module has four galvanically isolated input channels. The analog input
signals are coded using voltage/frequency converters (V/F) with an integration time of 20 msec.
The sequencer control coordinates the setting of the counters, the duration of the integration
time and the transfer of the counter results of the four input channels to the four measured value
memories.
The measuring range of each channel is adapted by the relevant sensor connection and by jumpers
in the front connector of the module.
The four 16 bit (2 bytes) wide measured value memories can be scanned one after the other by the
STEP 5 program using word operations. The 463 analog input module requires eight bytes of
address space.
The results of the measurements made on the various channels are stored under the addresses
ADB 0 to 2 ( Table 6-3).
The module address is set on a switch in the module cover.
The setting on the IM 306 is not significant for this slot.
However, for the sake of clarity, set the same address here.
