configured properties until after the configuration has been loaded.
When you assign the module parameters in STEP 7, you use various parameters to specify
the module properties. The following table lists the configurable parameters. The effective
range of the configurable parameters depends on the type of configuration. The following
configurations are possible:
● Central operation with a CPU
● Distributed operation on PROFINET IO in an ET 200MP system● Central operation with a CPU
● Distributed operation on PROFINET IO in an ET 200MP system
● Distributed operation on PROFIBUS DP in an ET 200MP system
When assigning parameters in the user program, use the WRREC instruction to transfer the
parameters to the module by means of data records; refer to chapter Parameter assignment

1) If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
each enabled channel will detect this fault.
You can prevent this message burst by assigning the diagnostics function to one channel only.
2) You can set the effective range of the diagnostics for each channel in the user program with data records 64 to 71.
3) You can configure the setting "Output substitute value" and the substitute value in the user program by means of data
records 64 to 71.
Short-circuit detection
The diagnostics for short circuit to ground can be configured for the voltage output type. A
short-circuit detection is not possible for small output values; the output voltages must
therefore be below -0.5 V or above +0.5 V.The diagnostics for short circuit to ground can be configured for the voltage output type. A
short-circuit detection is not possible for small output values; the output voltages must
therefore be below -0.5 V or above +0.5 V.

Open-circuit detection
The diagnostics for open circuit can be configured for the current output type. An open-circuit
detection is not possible for small output values; the output voltages must therefore be below
-3 mA or above +3 mSpecifies the number of sub-cycles per isochronous data cycle for the for the oversampling
function.
Missing supply voltage L+
Enabling of the diagnostics, with missing or too little supply voltage L+.
Wire break
Enabling of the diagnostics if the line to the actuator is broken.
Short circuit to ground
Enabling of the diagnostics if a short-circuit of the output to MANA occurs.
Overflow
Enabling of the diagnostics when the output value exceeds the overrange.
Underflow
Enabling of the diagnostics when the output value violates the underrange.
Reaction to CPU STOP
Determines the reaction of the output to the CPU going into STOP state.
Substitute value
The substitute value is the value that the module outputs in case of a CPU STOPThe module can be configured differently in STEP 7; see following table. Depending on the
configuration, additional/different addresses are assigned in the process image of the
outputs/inputs.
Configuration options of AQ 8xU/I HS
You can configure the module with STEP 7 (TIA Portal) or with a GSD file.
When you configure the module by means of the GSD file, the configurations are available
under different abbreviations/module names.
