GuardPLC DeviceNet Safety Scanner Chapter 5
Commission Safety Devices
In the HSP signal connection dialogs (in RSLogix Guard PLUS!
software), signals that are transferred over safety connections are
shown in white text on a red background. Signals transferred over a
standard connection are shown in blue text on a gray background.
The colorization applies only to the Connect Signals dialogs available
from the HSP protocol context menu. It is recommended that you use
a naming convention to visually distinguish between standard and
safety signals in the programming environment.
For example, use a prefix of std_ for any signals that are standard and
a prefix of safe_ for any signals that are safety-related.
Connect Signals Dialogs
You must commission all safety devices with the MAC ID and
communication rate, if necessary, before their installation on the
safety network. MAC ID and communication rate settings for the
DeviceNet safety scanner are made via RSNetWorx for DeviceNet
software.
A scanner can be configured by only RSNetWorx for DeviceNet
software which automatically becomes its configuration owner.
IMPORTANT
Any safety tags that appear in the Standard Connect Signals
window must be treated as standard values in your application.
Any standard tags that appear in the Safety Connect Signals
window must be treated as standard.
In order for a signal to be regarded as a safety value in your
application, the end device configuration must treat the signal
as safety and be transferred over a DeviceNet safety
connection.
