(1) The 1734-ACN adapter does not support POINT Guard Safety I/O modules.
ControlNet Connections for Distributed I/O
To communicate with distributed I/O modules over a ControlNet network, add
a ControlNet bridge, a ControlNet adapter, and I/O modules to the controller’s
I/O Configuration folder.
DeviceNet Communication To communicate and exchange data with CIP Safety I/O modules on DeviceNet
networks, you need a 1756-DNB module in the local chassis.
For information on how to install your 1756-DNB module, refer to the
ControlLogix DeviceNet Scanner Module Installation Instructions, publication
1756-IN566.
The 1756-DNB module supports communication with DeviceNet Safety devices
and standard DeviceNet devices. You can use both types.
