Polling Node Backup

Section 8-3

8-3

Polling Node Backup

If the polling node on the SYSMAC LINK Network has an error, the polling
node backup function of the SYSMAC LINK Unit will reconstruct the network
so that another Unit takes its place as the polling node. Refer to the following
diagram. The initial polling node is the Unit assigned node address 1. If the
Unit with node address 1 has an error, the node that has the next smallest
node address will automatically become the new polling node.

Note

While the network is being reconstructed, no communications are possible. If
the data link function was active, all data will remain at its present values.
When the network has been reconstructed, the data links will be reactivated.
The approximate time required for the reconstruction of the network can be
computed as follows:
(Address of new polling node + 1) x 20 ms + maximum node address x 1 ms

8-4

Node Bypass

Optical SYSMAC LINK networks can be connected to a backup power supply.
If a backup power supply is provided, the node bypass function of the SYS-
MAC LINK Units will operate whenever a node or node power supply fails. The
failing node will be bypassed in the network and the overall network will con-
tinue operating, preventing total network shutdown.

In this example, if the Unit assigned node address 3 has an error, the node
bypass function will eliminate this node from the network and the remainder of
the network will continue functioning.

Note

(1) With systems using optical transmission paths with a backup power sup-

ply, the backup power supply is given priority. Turn ON the backup power
supply first, then turn ON the PLC power supply, or turn ON both the
backup power supply and the PLC power supply at the same time. Com-
munications data will be corrupted is the backup power supply is turned
ON and OFF.
