Node Address (MAC ID)
NOTE
When using the Backup and Restore Module with a TCNM-ACBB5 connection box, the module Net
Type and Address Selection hardware switch settings are read at power-up and override the
software settings. For correct software configuration, make sure these switch settings are
compatible with your application.
The Media Access Control Identifier (MAC ID) is an integer identification value assigned to each node of the Fieldbus
network. The defined value distinguishes a node from all other nodes on the same link.
Selections:
(1)
Profibus a value in the range
0 - 126
(2)
DeviceNet
a value in the range
0 - 64
(3)
CC-Link a value in the range
1 - 64
(4)
CANopen a value in the range
1 - 128
(1)
For Profibus, the Node Address 126 forces the SSA (Set Station Address) service which allows the Fieldbus Master to
assign the slave node address. It is no longer possible to visualize the new address from the slave node after the
Master sets it.
(2)
For DeviceNet, the Node Address 64 allows the Fieldbus Master to assign the slave node address. It is possible to
visualize the new address from the slave node after the Master sets it.
(3)
The range of valid addresses for CC-Link depends on the assigned Input/Output Area Size as follows:
If the Input Area is greater than 6 or the Output Area is greater than 8, the max Node Address is 63.
If the Input Area is greater than 14 or the Output Area is greater than 16, the max Node Address is 62.
If the Input Area is greater than 22 or the Output Area is greater than 24, the max Node Address is 61.
(4)
For CANopen, the Node Address 128 forces the LSS (Layer Setting Service) which allows the Fieldbus Master to
assign the baud rate and address, but it is no longer possible to visualize the new address value from the slave node.
Data Flow Control
It implements a reliable transmission protocol between Fieldbus Master (PLC) and Slave (Fieldbus module) allowing
specific functionalities such as Synchronization, Fragmentation/Reassembling and Data Consistency. For more details
refer to the "DAD / DPD Driver" document on the CD-ROM.
Selections:
Disable
DAD Driver
DPD Driver
Data Consistency
If checked (enabled), it allows improving the overall communication robustness of the Fieldbus network. For more
details refer to the "DAD / DPD Driver" document on the CD-ROM.
Version
This parameter appears only if the Fieldbus type is CC-Link. It indicates the software version of the CC-Link controller.
The possible values are Version
1
or
2
.
Stations
This is a read-only parameter that appears only if the Fieldbus type is CC-Link. It indicates how many logical stations
are assigned to the physical slave.
Cycles
This is a read-only parameter that appears only if the Fieldbus type is CC-Link. It indicates the number of cycles the
CC-Link Fieldbus Master must perform on the logical stations in order to manage the Exchange Areas.
