with nodes in interconnected networks through the CVM1 or CV-series PC.
Up to three network levels are possible.
Note CS/CJ-series PC cannot be connected directly to SYSMAC NET networks
and CJ-series PC cannot be connected directly to SYSMAC LINK networks
The programming and monitoring of other PCs on the network can be con-
ducted from Programming Devices connected to the PC’s CPU Unit. Inter-net-
work connections are possible in this case also and can cover up to three
network levels.
Improved Error Handling
An error log enables quick handling of errors by recording the time the error
occurred and error details. The current Controller Link Unit and Support
Board status are also available, as are the data link and network status.
When an error occurs in the polling node that controls the Controller Link Net-
work, another node automatically becomes the polling node. This prevents an
error at a single node from influencing other nodes on the network, achieving
a highly reliable system.
