Reference Manual 123
Profibus Settings, Profibus SC5000 Redundant
(SC5000 Profibus models)
Node Address
Enter a Node Value in the field provided, to define the value that distinguishes this
node from all other nodes on the same link. Each node identifies a device within the
network.
Valid values are in the range 0 - 126.
Node Address 126 forces the SSA (Set Station Address) service which allows the
Fieldbus Master to assign the slave node address.
Node Address (Working/ Protecting) SC500 Redundant
Enter a Node Value in the fields provided, to define the value that distinguishes
these nodes from all other nodes on the same link. Each node identifies a device
within the network. The behavior is controlled by the IP Selector parameter
in Modify Settings | Global Settings | Redundant Operation.
Valid values are in the range 0 - 126.
Node Address 126 forces the SSA (Set Station Address) service which allows the
Fieldbus Master to assign the slave node address.
Master Input Area Size
Enter a value from 8 - 144 bytes to define the size of the message command sent
from the Fieldbus module to the Fieldbus Master (Host). The default value is 8
bytes.
The maximum Input + Output Area Size for the Profibus interface is 152 bytes.
Master Output Area Size
Enter a value from 8 – 144 bytes to define the size of the message command sent
to the Fieldbus module from the Fieldbus Master (Host). The default value is 8
bytes.
The maximum Input + Output Area Size for the Profibus interface is 152 bytes.
MAC Address
This is a read-only parameter. It displays the address of the Profinet channel
reserved for internal communication.
