The output module is not an autonomous module, but rather an extension of the S7-Xplorer module. With the output module, you can write data from ibaPDA to a controller.

|---|---|
 |
Depending on the configured protection-level access of the S7 CPU, writing values into the CPU may be not possible. |
Enable the S7 outputs in the interface settings, see General interface settings.
You can configure the module via the Outputs tab. You do not have to add it separately. The module is available as soon as you add an S7-Xplorer module in the Inputs register.
For more information on the module settings see General module settings.
Module-specific settings
Calculation timebase
Timebase (in ms) used for the calculation of the output values.
Technically, the calculation timebase is identical to the timebase of the input module. This means a change in the calculation timebase also changes the module timebase of the input side and vice versa!
The calculation timebase is not the same as the output timebase, with which the values are output!
Minimum output timebase
Timebase with which the outputs can be updated as quickly as possible.
The value is acquired automatically by the system based on the current I/O configuration and is only displayed here. The output timebase results from the smallest common multiple of all module timebases or is at least 50 ms.
Number of analog output signals
Define the number of configurable analog signals in the signal table. The default value is 32 for each. The maximum value is 1000. The signal table is adjusted accordingly.
Digital signals are not supported for the output module.
Send mode
Determines when new data is written to the controller:
-
Cyclic: Data is written cyclically at the set update time.
-
On change: Data is written each time the signal data is changed.
-
On trigger: Data is written with every rising edge of the trigger signal.
All signals of a module are always written, regardless of the write mode.
Trigger signal
This field only appears when the "on trigger" send mode is selected. Select here a digital signal. A rising edge on this digital signal writes the signal values taken at the time of the rising edge.
Signal configuration
You can configure the signals to be output in each case via the expression editor. Open the expression editor via the <fx> button in each signal row.

ibaPDA reads and writes all signals for an Xplorer module via a common connection. Therefore, the total number of configured signals influences the update time. |
