Explanation
Description
No. 8
Specification of the
process for station
naming
The position of slide switch No. 8 determines the process for
station naming.
In the OFF position, the device uses the name saved in persistent
memory represented as an empty character string (NIL, "") in the
default setting. The "DCP Set" service must be used to change the
name of the device in the EEPROM.
In the ON position, the device uses the instance of sections of two
predetermined device names determined by slide switch Nos. 1 - 7
as listed below.
No. 7
Specification of the
predefined device
name section
Provided that station naming is activated via the DIP switch (slide
switch No. 8 in position ON), the position of slide switch No. 7
determines the fixed part of the device name.
In the OFF position, the device uses the character string "wago-
750-375" as the fixed part of the device name.
In the ON position, the character string "wagox750x375" is used.
No. 6
Reset to factory
settings
If all slide switches except No. 6 are in position ‘OFF’' the fieldbus
coupler waits after start-up for the operation of any slide switch to
reset the factory settings before finally starting the firmware.
While waiting the RUN-LED is flashing at a frequency of 1 Hz.
After operation of at least one slide switch the RUN-LED flashes
at 2 Hz while persistent data structures are initialized. Subsequent
an automatic restart of the firmware is initiated. All PROFINET IO
specific settings, e.g. the persistent device name or the persistent
IP settings, contain the delivery states afterwards.
No. 1…6 Specification of the
device name
instance
Slide switches 1 - 6 specify the instance of the predefined device
name section.
If all slide switches are in the OFF position, nothing (NIL) is
added to the specified character string.
In any other case, a separator is added depending on the position of
slide switch No. 7, either "-" (OFF) or "x" (ON). That is followed
by a decimal point formed from the positions of slide switches No.
1 - 6.
This decimal value of the device name instance is based on the
following rule:
6
Instance =
∑
Switch position (n) * 2
(n-1)
n=1
In the ON position, the respective switch position takes the value
"1" and in the OFF position, the value "0".
