Description/setting options
Undervoltage messages are filtered; a maximum
of one message per module is sent via the net-
work. The undervoltage is also indicated by the
"SF" LED flashing on the bus module.
Channel alarms are reported individually via the
network.
Channel alarms (e.g. short circuit or under-
voltage) are combined and sent as a common
message via the network. The error is also indic-
ated by the relevant LED flashing on the bus
module.
Defines how the process values of the analogue
modules are displayed.
Setting options:
– Byte order Intel (LSB-MSB, "Little Endian"):
Process values are displayed in Intel format
(least significant bit on the left, most signific-
ant bit on the right)
– Motorola byte order (MSB-LSB, big Endian):
Process values are displayed in Motorola
format (most significant bit on the left, least
significant bit on the right)
This parameter can also be set via the I/O dia-
gnostic interface, using function number 4402 in
bit 7:
– Value "0": Intel (LSB-MSB)
– Value "1": Motorola (MSB-LSB)
The settings for the byte order and process value
display depend on the higher-order controller
and the associated user programs.
