Use RSNetWorx for
ControlNet Software

order to activate the configured I/O devices in your application. You must also

RSNetWorx for ControlNet software stores information in keeper devices. These
ControlNet communication modules are keeper-cable devices:

•
1756-CN2 and 1756-CN2R modules
•
1756-CNB and 1756-CNBR modules
•
1768-CNB and 1768-CNBR module
•
1769-L32C and 1769-L35CR controllers
1784-PCICS and 1784-PKTCS cards
If you configure a keeper on one network and then use it on another network, the
conflicting information can make it difficult to use RSNetWorx for ControlNet
software to schedule the new network. In extreme cases, it may be difficult to go
