ways. The standard setting is use as a digital
I/O slot, where Pin 4 can be used as a digital input or output.

Note
The "Factory reset" command does not affect the configuration of the extension
port in any way.
Note
The process data length depends on the configuration.
The extension port can be configured using the parameter 55
hex
(see table). If data storage
or validation is used, validation (identical) must be used for configuring. Depending on the
system, the Device ID has to be entered (parameter data table) or the Device ID is read out
from the IODD.
Setting the serial
number 54
hex
The serial number has a default value of 16x00
hex.
In order to use the "Identity" master validation mode, a serial number can be set using this
parameter.
This prevents a device from connecting to the wrong master port.
