selecting Open Package Folder .
Input and output size
PROFINET has an internal device with maximum 2048 digital input signals and
maximum 2048 digital output signals. Similarly, for safe PROFINET internal device,
you can add safety digital input signals and safety digital output signals.
The internal device PN_Internal_Device has two system parameters, Input Size
and Output Size . Input Size is used to configure the input size of the internal device
and Output Size configures the output size. A connecting PLC needs to have a
slot configuration created in the external PROFINET configuration tool that matches
the configuration of the internal device.
The following table shows a few examples of how the Input Size and Output Size
parameters can be used to create different slot configurations of a connecting PLC:
Step 7 Configuration Output Size Input Size
Slot 1: DI 8 bytes 8 bytes 8 bytes
Slot 2: DO 8 bytes
Slot 1: DI 16 bytes 16 bytes 8 bytes
Slot 2: DO 8 bytes
Slot 1: DI 32 bytes 32 bytes 64 byte
Slot 2: DO 64 bytes
Tip
If a configuration mismatch between the connecting PLC and the internal device
occurs, an event message is generated on the FlexPendant. This event message
informs the user of the present slot configuration of the internal device.
Note
The Input Size sets the size on digital outputs and Output size sets the size on
digital inputs, seen from the PLC’s point of view.
