The load cell input signal is processed in the input module s 16-bit A/D converter and digital signal processor from where it can be fed to either channel 3 (CH3) or channel 4 (CH4) or both. Status input D1 is internally assigned to channel 1 (CH1) and status input D2 is inter nally assigned to channel 2 (CH2).
CH1 is configured f or frequency measurement f or D1 in Code 2. CH2 is configured f or frequency measurement for D2 in Code 4. Selecting the load cell output f or CH3 is configured in Code 5 and f or CH4 in Code 6.
The line frequency rejection setting, sensor input r ange in mV/V, and the output rate are all selected in the smart register 1 (SMT1) menu in Code 2.

buttons at the same time to enter the main programming mode.
Press the
button three times to enter Code 2. Set Code 2 to [X77].
This setting enters the smart register 1 code setup menu.
Note the output registers in the 3rd digit are specific to the ISSC / ISSD input module. These registers vary for each different smart input module.
Press the
button to enter SMT1.
This menu provides settings unique to smart register 1 of input module ISSC/ISSD.
Using the
buttons, select:
1st Digit: 50 Hz line frequency rejection for 50 Hz power supply areas, or 60 Hz line frequency
rejection for 60 Hz power supply areas.
2nd Digit: The sensor input range.
3rd Digit: The output rate.

In our example, a hopper fills boxes travelling along a conveyor belt. A rotary encoder monitors the conveyor speed and a light beam sensor indicates when the bo x to be filled is in position belo w the hopper. A load cell under the conveyor weighs the box.
The rotary encoder is connected to status input D1 and assigned to CH1. The light beam sensor is connected to status input D2 and assigned to CH2. The load cell is configured f or 3 mV/V input with 50 Hz line frequency rejection. As the boxes are filled relatively quickly, the averaged output rate is set to 10 Hz on CH3.
The frequency output from the encoder is in the 0 to 1 kHz r ange (360 pulse/revolution). The light sensor has its beam broken at a much slower rate.
