33000SafetySafety3-3.1Intended use3100Intended use3-Bestimm_Verwendung_BAWS
The operating mode selector switch enables you to switch between de-
fined operating modes such as set-up, shutdown, automatic operation
and service. An actuator is used to assign access rights and authorisa-
tion to switch operating modes.
A safety system must be used to evaluate the operating modes. Switch-
ing must not initiate a hazardous movement, nor can it cancel an existing
control command.

44000Function descriptionFunction description4-Funktionsbeschreibung_allgemein_BAWS
The operating mode selector switch enables you to switch between 5
different operating modes. Operating modes OM1 ... OM4 plus a special
service mode (OM5.)
For OM1 ... OM4, one button each is available. For the special service
mode (OM5), button 1 must be operated for a certain time period (see
Time monitoring -> Operating time). Each button is assigned a moni-
tored semiconductor output. Operating the button changes the semi-
conductor output from low to high. The semiconductor outputs must be
evaluated via a safety control system. The operating mode selector
switch guarantees that only one of the semiconductor outputs is high at
any one time.

The operating mode selector switch is protected against unauthorised
operation. A switch between operating modes must be enabled via an
actuator.
There are 5 actuators in total; each actuator provides authorisation to
switch up to 5 operating modes, including special authorisations:
Actuator Key Mode 01: OM 1
Actuator Key Mode 02: OM 1 and 2
Actuator Key Mode 03: OM 1 and 2 and 3
Actuator Key Mode 04: OM 1 and 2 and 3 and 4
Actuator Key Mode Service: OM 1 and 2 and 3 and 4 and 5 (Service)
When the actuator is removed, the set operating modes OM1 – OM4 are
retained.
Service mode (OM5) is an exception. When the "Service" actuator is re-
moved, the mode switches to OM1.

4.1 Key ID number of the actuator
4 Function description
4.1Key ID number of the actuator4100Key ID number of the actuator4-Key_ID_Nummer
Once an actuator has been connected, the actuator's unique Key ID
number is downloaded to the higher-level process controller using a de-
fined protocol.
The Key ID number is used to clearly identify the actuator and is unique.
It is printed on the actuator's type label as a 9-digit decimal figure.
The Key ID number consists of two parts:
Bit 27 … 24 is the Key Mode
Bit 23 … 0 is the consecutive number.
Example:
INFORMATION
Please note that the Key ID number is not printed on the actua-
tor packaging.
If the actuator is lost, it is impossible to supply a replacement
actuator with an identical Key ID number.

Key:
Download procedure:
IDsync - The "IDsync" signal indicates that the download has started
- The "IDsync" signal is present for 100 ms
IDclock - T = 100 ms
- Duty cycle = 50 %
- The "IDclock" signal is driven by the operating mode selector switch
IDo0, IDo1 - Data output;
these signal lines are used to download the Key ID number from the operating mode selec-
tor switch to the control system.
Bit 27 … Bit 14 are sent via the data line IDo0.
Bit 13 … Bit 0 are sent via the data line IDo1.
IDi0, IDi1 - Data input;
The control system uses these signal lines to confirm receipt of the previous Key ID number
(Bit 27 … Bit 0) to the operating mode selector switch.
Bit 27 … Bit 14 are received via the data line IDi0.
Bit 13 … Bit 0 are received via the data line IDi1.
(a) The operating mode selector switch sets the "IDsync" signal, thereby signalling to the control system
that transmission is starting
(b) A rising edge at the "IDclock" signal indicates that the data ("IDo0" and "IDo1") is present and valid and
is being read in by the control system.
(c) The control system must output the data that was read in to lines "IDi0" and "IDi1" by the time there is
a falling edge at the "IDclock" signal.
(d) With a rising edge at the "IDclock" signal, the operating mode selector switch reads the feedback from
the control system at IDi0 and IDi1 and checks it for equivalence.
(e) Even at the end of the download, the control system must leave the data for at least 100 ms after the
last rising edge at the "IDclock" signal.

INFORMATION
If the control system does not feed back the previously read Bits
correctly, the download is aborted and restarted. The "IDsync"
signal is set once again. The download is repeated until the Key
ID number is downloaded completely.
The download of the Key ID number takes 1.4 s.
