Numerical format for Siemens function blocks

For fieldbus masters with the ability to evaluate the status information within the data word, i.e. Siemens format.

The status information is contained in Bit B0 .. B2.

The digitized input is placed at the position Bit B3 .. B15.

Technical description

This description is only intended for hardware version X X X X 2 A 0 0 - - - -.

The serial number can be found on the right side of the module.

The input channels are differential inputs and they have a common ground potential.

The inputs are connected to +I and -I. The shield is connected to "S". A capacitive connection is made automatically when snapped onto the DIN rail.

These I/O modules are not provided with integrated power jumper contacts. The power supply is made by the data contacts with a DC-DC converter. The modules can work self-supporting.

The input module can operate with all buscouplers of the

WAGO-I/O-SYSTEM (except for the economy type).

Attention

The value of the input signal should be in a range of 0V to 10V or no signal.

Numerical format

All analog values will be shown in a unit numerical format. The resolution is 12 Bits and the 3 LSBs are not significant.
