Analog Input/Output Modules

9.4.3Special Features of the 463 Analog Input Module

The 463 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed.

Adaptation of the The measuring range for each channel is adapted by appropriately connecting

Measuring Range the sensors and with jumpers in the front connector of the module (see the front connector assignments).

Note

The ohmic resistance of the jumper with which the measuring range is set is also measured. As the resistance of this jumper is not inconsiderable (0.5 to

0.7ohms in relation to the measuring shunt of 50 ohms) when I/O module cables with integral connectors and subsequent wiring blocks are used, the measurement result may be corrupted accordingly.

9.4.4Setting the Module Address

 

You set the module address on the addressing switch. This also establishes

 

the necessary assignments between user program and process connection.

 

The module address is the sum of the decimal significances of the switch

 

rockers in the On setting (￿).

 

One data word = two data bytes is required to process an input or an output.

 

A module with 4 inputs therefore reserves 8 byte addresses.

Labeling Field

You can affix the adhesive label with the desired module address on a free

 

labeling field under the addressing switch.

 

The switch rockers to be set for the module address specified as a decimal

 

number (address bit ADB) are marked by dots on the label. The unmarked

 

switches should be switched off.
