Controller ID
The Controller ID (SRS) uniquely identifies a particular GuardPLC
controller within a network of controllers. Its use ensures that this
configuration is applied to the correct controller. Specify the
Controller ID of your selected GuardPLC controller, or this will
automatically be provided when you associate the scanner and
controller as described in Chapter 7.
Scanner ID
The scanner ID is a read-only value which uniquely identifies the
scanner and is required to connect the GuardPLC controller to the
scanner. The scanner ID is automatically generated by RSNetWorx for
DeviceNet using the SNN and DeviceNet address of the scanner. It is
exported in the Scanner Signals file and is viewable in the associated
RSLogix Guard PLUS! project.
HSP Signature
The HSP Signature is a read-only value that is unique to each layout of
the signals within the data exchanged between the GuardPLC
controller and the 1753-DNSI. The HSP Signature is calculated based
on the scanner’s configured safety and standard connections and any
target connections defined in RSLogix Guard PLUS!. It is passed to
RSLogix Guard PLUS! via the Scanner Signals File. The HSP signature
changes only when a modification occurs in the layout of the signals
exchanged between the controller and scanner.
