It should be noticed that every time that Profibus communication is established, the
parameterization string will be sent to the device writing the parameters to the set up values.
the values in parameterization string shall be modified at the Master station.
byte 0-2 reserved for dpV1
byte 3
storage format
this byte defines the format of the variables that are transmitted on 2 or 4 bytes.
the setting of this parameter affects the format of the following data:
Output data:
(if module 2 is selected)
set point
Input data:
(if module 2 is selected)
current position
General data:
slot 1 index 1
current position
Value:
0: Lsb byte is transmitted first (default setting)
1: Msb byte is transmitted first
byte 4
fail safe action
this byte defines the action of the actuator in case of loss of signal. the action takes
place only if the local selector is on remote position and if the bus is operating. When
the bus signal restores, also the actuator restores at its normal functioning.
Value:
0: Off - disable (default setting)
1:
close
2:
Open
3: stay put
4: Go to position indicated in the parameter ‘safe position’
important
: fail safe action is active only if watchdog control is enabled.
note
* new version of f02 / EPI2 has only opening /
closing speeds 4, 6 and 8 (see VcIOM-02819-En)
