Diagnostic information in the process data when using a
Siemens controller type S7
If the parameter "Show Siemens additional bits" (R32, bit 4) is activated, bits 0 to 2 of
the process data are used for status evaluation�
The process date is shown in bits 15-3 with bit 15 as the sign bit�

8.3.4 AC2637 FieldModuleDP 4AO (C) M12
The analogue output module AC2637 generates an analogue output signal of
0/4���20 mA�
The four channels feature electrical isolation from the supply voltage and a
common ground� The module operates with an accuracy deviation of max� ± 0�1%
of the final value of the measuring range
The outputs can be scaled via the fieldbus; the settings made are stored in the
module�
The actuator is connected via /-� The actuator can be operated optionally
with 24 VDC� In order to ensure effective discharge of the immission, the ground
surface must be conductive and feature low-resistance earthing�
Pin 5 (shield) is capacitively coupled to the conductive base surface of the module�
