Alternatively, to the parametrization of terminal device 6 can also by unshowned, be attached on bus coupler 4
Programming device or realized by data input device 23, described data input device 23 is connected with higher level's control device 2.
Other terminal devices 7 to 11 equally can be connected with bus coupler 44 in the case of using suitable connection cable 12,
Thus, equally it is capable of parameterizing by bus coupler 4 or by data input device 23 and higher level's control device 2.
Alternatively, it is possible to regulation：Direct-coupling by terminal device 7 to 11 and the terminal device 6 according to the present invention
To carry out the direct parametrization to these terminal devices.Exemplarily, between terminal device 6 and terminal device 8 by means of
Parametrization cable 24 can be inserted into the communication interface of terminal device 6 and 8 arranging this coupling, described parametrization cable 24
In 15.For the voltage supply of described two terminal devices 6 and 8, parameterize cable 24 and include voltage source 25, such as grid equipment
Or battery.
For example, if terminal device 6 passed through first higher level's control device 2 and attached data input device 23 or
By bus coupler 4 with the programming device that has been not shown is parameterized and the function of described parameterized terminal device 6
And then the run duration in the automated system 1 according to Fig. 1 enters into force（validieren）, then can arrange such
Direct parametrization to the terminal device 7 to 11 in described automated system 1.And then, for example by automated system 1
From bus coupler 4 disengagement phase, terminal device 6 can be disengaged and also by means of parametrization cable 24 and terminal device 8 or
One of person's terminal device 9 to 11 is connected.
Specify to execute for the parameterized procedure of the terminal device 8 being then connected：User is by means of operation dress
Put 19 to be given for processing meanss 17 with the first functional status of the communication of bus coupler 4 from being given for being transferred to
Parameterized second functional status to the terminal device 8 being connected in IO-Link communication interface 15.For described switching,
First pass through switching device being assigned to processing meanss 17, having been not shown（This switching device can be especially processing meanss
17 program module or software module）, will instruct and export communication module 16 from processing meanss 17, and thus lead to initialize
Signal is supplied to IO-Link communication interface 15.Here is it is preferable that suitable signal to be provided by processing meanss 17 and by leading to
Believe module 16, especially required initializing signal is converted into the communication module 16 of the type of level translator.
This initializing signal can be especially the commutation of signal level（Invertierung）, this signal level is first logical
Cross parametrization cable 24 to connect come the communication being attached to described two terminal devices 6 and 8 in the case of connecting two terminal devices 6 and 8
On mouth 15.By this initializing signal, in the way of according to IO-Link communication protocol regulation, to notify terminal device 8：From present
Play the parametrization that carry out to this terminal device 8.After initializing signal reaches, terminal device 8 can will be ready
Signal passes through parametrization cable 24 and is supplied to terminal device 6.Standby ready signal incoming terminal equipment 6 processing meanss 17 it
Afterwards, processing meanss 17 by the parameter being stored in parameter storage 18, in particular for process sensor signal parameter and/
Or it is supplied to end by parameterizing cable 24 corresponding to the coding of IO-Link communication protocol for processing the signal of action command
End equipment 8.After the end of transmission of parameter, parameterized terminal device 8 to be carried out return signal is sent to terminal device
6, complete parameter transmission for confirmation.
Exemplarily, can specify that：After sending return signal, terminal device 6 is from the second function of processing meanss 17
State is transferred to the first functional status of processing meanss 17.Thus, not only terminal device 6 but also terminal device 8 are ready to
Termly（regulaer）As IO-Link terminal device or " device ".
Automated system 41 shown in figure 2 is different from the automated system 1 according to Fig. 1 only by following manner：
Bus coupler 44 to construct not in accordance with IO-Link communication standard, but is more specifically configured to switching signal
It is supplied to terminal device 6 to 11 and be configured to receive switching signal from terminal device 6 to 11.In automated system 41
In, not only the terminal device 6 to 11 of IO-Link ability and connection cable 12 can with the automation according to Fig. 1
In system 1, identical mode is using.Certainly, following switching signal, described switching signal are only transmitted by connection cable 12
For example lead to action between inactive state and functional status for the actuator.Additionally, by the terminal device including sensor（As this
It is exemplarily as this situation in terminal device 6）Only switching signal is transferred to bus coupler 44.
For example, when the terminal device 6 being configured to distance meter determine object to be scanned apart from when, just permissible
Carry out the such transmission to switching signal, described distance is under the limit that can be previously given.Especially, can by by
In operation device 19 and display device 20, the regulation to this limit is carried out to the parametrization of terminal device 6.If deposited with regard to this
Store up the parameter in terminal device 6, the parameter in particular for process sensor signal and/or the ginseng for processing action command
Number should be forwarded to other terminal devices 8 to 11, without using additional programming device, then terminal device 6 with
Direct parameter transmission is set between described other terminal device 8 to 11, transmits as described direct parameter and tie with Fig. 1
As conjunction is described.Here, terminal device 8 to 11 can be optionally to construct simultaneously with terminal device 6 identical mode
And the parametrization being therefore equally arranged for other terminal devices, or described terminal device 8 to 11 be configured to by
Standard terminal equipment according to IO-Link communication protocol and be unable to realize the parametrization to other terminal devices.
