The Scanner Signals File separates data transferred on safety
connections from data transferred over standard connections.
Signals created in the RSLogix Guard PLUS! Signal Editor can be
assigned to scanner I/O data signals, allowing them to be used by the
GuardPLC application logic.
Target Connections File RSLogix Guard PLUS! generates the Target Connections File (.tcf) to
inform RSNetWorx for DeviceNet which application signals should be
exposed on the scanner’s DeviceNet slave mode or target interfaces.
As described in the Scanner Signals Files section, RSNetWorx for
DeviceNet chooses locations for these target signals within the data
tables that are exchanged over the HSP connection. See ‘How Data
Tables Work’ on page 1-4 for more information on how safety and
standard data is organized in a GuardPLC system that uses the safety
scanner.
Automatically Update
Signals The simplest way to associate the 1753-DNSI and the GuardPLC
controller is to select Automatically Update Signals on the safety
scanner’s GuardPLC tab. This option is only available when RSLogix
Guard PLUS! and RSNetWorx for DeviceNet are installed on the same
computer.
1. Open the Device Properties dialog by double-clicking on the
scanner you want to associate.
2. Select the GuardPLC tab.
3. Select the Automatically Update Signals option.
