2.2
Function parameterization
2.2.1
Scan physical structure and store in the XNE-1SWIRE
In order for the SWIRE bus to start operation, the physical structure must match the
SWIRE configuration stored in the XNE-1SWIRE. On power up, the physical struc-
ture of the SWIRE bus is scanned and compared with the SWIRE configuration
stored in the XNE-1SWIRE (configuration check of number of slaves, type and
assigned address). If the physical structure of the SWIRE bus does
not
match the
configuration stored in the XNE-1SWIRE (SW LED flashing):
•
the physical structure of the SWIRE bus must be stored in the XNE-1SWIRE
•
or the physical structure must be corrected.
The parameter setting determines how the physical structure of the SWIRE bus is
stored:
•
manually (see Section «Manual SWIRE configuration (default setting)»,
Page 12),
•
or automatically (see Section «Automatic SWIRE configuration», Page 12).
Storing with manual and automatic SWIRE configuration:
•
The slaves physically located on the SWIRE bus are scanned.
•
Each slave is assigned with an address and stored in the corresponding slave.
•
The configuration is stored in the XNE-1SWIRE.
Manual
SWIRE configuration
(default setting)
To store the physical structure of the SWIRE bus in the XNE-1SWIRE, the CFG
button of the XNE-1SWIRE must be pressed manually (only functions if the SW LED
is flashing).
Parameter setting:
•
PROFIBUS-DP and CANopen (Byte 1):
• Disable CFG = 0 (MXpro: «automatic configuration SWIRE» = deactivate)
•
DeviceNet (Attribute 121 (79
hex
) «PARAM_COMMON_OERATION_MODES»):
• Bit 1 = 0
Automatic
SWIRE configuration
If the physical structure of the SWIRE bus does
not
match the configuration stored
in the XNE-1SWIRE on power up, the physical structure is stored automatically in the
XNE-1SWIRE.
Parameter setting:
•
PROFIBUS-DP and CANopen (Byte 1):
• Disable CFG = 1 (MXpro: «automatic configuration SWIRE» = activate) and
• MC = 0 (MXpro: «Moeller compliant» = deactivate)
•
DeviceNet (Attribute 121 (79
hex
) «PARAM_COMMON_OERATION_MODES»):
• Bit 1 = 1 and
• Bit 4 = 0
• Only the manual SWIRE configuration is possible if the «Moeller Con-
formance» function is active.
• The XNE-1SWIRE is factory set with a stored configuration of «Zero»
slaves.
