Explanation of parameters
Potential group
Specifies whether the a light BaseUnit with incoming voltage supply is located in this slot
(see system manual ET 200SP Distributed I/O System
(http://support.automation.siemens.com/WW/view/en/58649293)).
Operating mode
Selection of the operating mode in which all of the module's channels are operated.
● DI (Page 13) / Oversampling (Page 48)
● Counting
When configuring with HSP0229 for STEP 7 or with a GSD file, the operating mode is
specified by selecting the module name.
Diagnostics: No supply voltage L+
Enabling of the diagnostics for no or insufficient supply voltage L+.
Diagnostics: Short-circuit to ground
Enabling of the diagnostics if a short-circuit of the actuator supply to ground occurs.
Channel enabled
Determines whether a channel is enabled or disabled. If a digital input is disabled, the
module ignores its signals.
Input delay
This parameter can be used to avoid signal faults. Changes to the signal are only detected if
they are constantly pending longer than the set input delay time.
Isochronous configuration is only possible if there is an input delay of 0.05 ms configured for
at least one channel. In isochronous mode, the feedback interface is updated at the time T
i
(time for reading the input data).
Note
If you select the "0.05
ms" option for the input delay, you have to use shielded cables for
connection of the digital inputs.
