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 No.
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-750-370” as the fixed part of the device name.
In the ‘ON’ position, the character string “wagox750x370” is
used.
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”.
Example:
The following example of a DIP switch setting illustrates the structure of the
respective device name.
Slide switch Nos. 1, 2, 4, 7 and 8 are moved to the ‘ON’ position.
