NOTE 3: Special characteristics for the DIP switch setting different to DIP1 to DIP6 “000000”
,
i.e. hardware configured Node ID
• Bus mode büS (bueS) or CANopen:
The behaviour with this DIP switch setting depends on the bus mode (büS (bueS) or CANopen).
The
factory setting is büS (bueS).
The bus mode can be changed by software only - see chapter
“6.19.4 Access to further parameters (cyclic and acyclic)”.
• Device addressing using DIP switches in the:
büS (bueS) mode:
The parameter “Fixed CANopen address” (“Static Node ID”) is automatically
updated to the address value currently set via DIP switches when a restart
occurs.
The parameter “Fixed CANopen address” (“Static Node-ID”) is automatically
updated to the address value currently set via DIP switches after a restart.
In this mode, the device is prepared at the factory for the use with a precon-
figured gateway, i.e. the input connection for controlling the solenoid valves has
already been configured.
Details are clarified in chapter “6.13.3”.
CANopen mode:
The device address (Node ID) is used which is set via DIP switches.
6.13.3 Factory settings of the control head regarding the gateway
configuration
Factory settings:
Bus mode: “büS”,
Addressing: software configurable Node ID
(i.e.
DIP1 to DIP6 = 000000
) - see details in NOTE box 2 above.
If DIP1 to DIP6 differ from the factory setting:
This means:
if DIP1 to DIP6 > 000000
(device address fixed by DIP switches - see NOTE box 3)
and
the DIP
switch position was changed after the last device restart, the control heads will be configured according to a preset
rule at the next device restart. This automatically configures the setpoint producer for the control ofthe solenoid
valves. The
factory default setting
is defined:
“Presetting Rule”
= “1” for systems with a preconfigured gateway
(“Gateway_8681”). This results in an automatic adaptation according to the node ID (>0, set via the DIP switches)
of the respective control head.
From firmware version B.02.00 onwards, it is possible to change the (preconfigured) setpoint producer via “büS-
Map” with the Bürkert Communicator for e.g. a standard büS system (without preconfigured gateway).
Changing the DIP switches to a value > 000000 and then restarting the device will overwrite any changes made
via the Bürkert Communicator with values according to the preset “presetting rule”. This presetting rule is defined
by the parameter
“presetting rule” (“Use Special Sensor Index”)
which can be found in the Bürkert Communicator
under: Control Head / General Settings / Parameters / Presettings büS mapping.
When returning to the factory default setting
(
with fixed device address
), after changing the presetting:
- ensure that the parameter
“presetting rule”
is set to “1”
- note the previous DIP switches position
- set DIP1 to DIP6 to factory default setting 000000, then restart the device
- set DIP1 to DIP6 to the noted DIP switches position, then restart the device again.
Details on the büS network configuration (“büS map”) are described in the operating instructions for the Bürkert
Communicator (Type 8920 - see chapter “5.6.1”).
