Configure Your Controller for DeviceNet Communication Chapter 7
Setting Up the Controller as a
DeviceNet Standard Slave
As a DeviceNet standard slave, the controller can perform standard I/O
communication with 1 standard master for up to 2 connections, by using up to 16
bytes per connection (128 bytes for input data for EtherNet/IP communication).
The SmartGuard controller can also respond to explicit standard messages.
The controller’s internal-status information and a specified area of I/O can be
allocated in the standard master.
For the SmartGuard controller to perform standard I/O communication as a
standard slave, standard slave I/O data must be created and I/O connections
must be configured in the standard master.
Create Standard Slave I/O Data
Follow these steps to create standard slave I/O assemblies.
1. In RSNetWorx for DeviceNet software, right-click the SmartGuard
controller that will act as the standard slave and choose Properties.
2. Click the Slave I/O tab.
3. Configure the slave controller to either clear or hold the last data for an
input assembly that the slave controller transmits to the standard master
when:
• the slave controller changes from Run to Idle mode.
• the controller detects an error, such as a communication error in a safety
chain that sets the data to an I/O tag in an input assembly.
IMPORTANT
Data written to the SmartGuard controller via its standard slave connection
must be considered as non-safety and must not be used to control safety
functions in the SmartGuard application program.
