Messages
You can read and write to controller parameters by sending DeviceNet
explicit messages to the SmartGuard controller. The controller
processes the received messages and returns a response. The
messages described in these tables are supported by the SmartGuard
controller.
ATTENTION
The data attributes handled by standard I/O communications
and explicit message communications are non-safety data. The
necessary measures for safety data are not taken during
generation of standard or explicit message data. Do not use
this data to operate a safety control system.
