Please consider to check the Enable S7-Xplorer outputs option in the I/O Manager on the root node S7-Xplorer in order to use outputs.

Only the module type S7-Xplorer can be used for outputs.

Modules that have already been defined at the input level can also be seen in the tree of the output interfaces and can be used for output signals.

Except for the calculation timebase and the minimum output timebase the general module settings are identical to those on the input side and are retained.

The number of analog and digital signals (module layout) can be set differently.

For notes on the general module settings see General module settings.

S7

Unlike to the input side there is an additional setting Write mode.

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.

The connection settings are identical for inputs and outputs.

Configure the desired output signals in the Analog and Digital tabs. Enter name and expression and select the desired symbol in the PLC using the symbol browser or enter the S7-operand.

If you make your selection of analog signals in the symbol browser, the corresponding data type will be applied as well. Without symbol browser you can enter the symbol name an select the data type of analog signals. The following data types are available for analog signals:

BOOL, CHAR, BYTE, WCHAR, WORD, DWORD, SINT, INT, DINT, LINT, USINT, UINT, UDINT, REAL, LREAL, S5 REAL, TIME, LTIME, TIMER, COUNTER, STRING[], WSTRING[], CHAR[], WCHAR[]
