Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the relevant information is not taken into account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific

14 Manual, 03/2012, A5E03574157-01
4.2 Declaration of parameters
Diagnostics missing supply voltage L+
Enabling of the diagnostics for missing or insufficient supply voltage L+.
Short-circuit to ground diagnostics
Enabling of the diagnostics in the event of a short-circuit of the sensor supply to ground or of
an input to the sensor supply.
Diagnostics wire break
Enabling of the diagnostics if the module has no current flow and/or the current is too weak
for measurement at the correspondingly configured input.
Operating mode
Determines whether a channel is enabled or disabled.
Input delay
Determines how high the input delay is for a channel.
BaseUnit with incoming supply voltage
Specifies whether the I/O module is located on a BaseUnit with incoming voltage supply (see
system manual ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293)).
