9.6 DeviceNet
DeviceNet complies with CAN based protocol and provides the following features:
• DeviceNet Group 2 Server implementation.
• Bus Powered Network Interface allows power alarm information to be communicated when actuator
loses main power. The actuator does NOT drop off the network when 3-phase power is lost.
• Standard Polled I/O Connection
• Standard Bit Strobed I/O Connection
• Standard Change of State / Cyclic I/O Connection
• Standard explicit connections defined as:
• Various Assembly Objects and sizes that allow the network user to determine how much data to
transfer to accommodate network installation data throughput requirements.
• Automatic BAUD rate detection.
• Node Address configurable via local setup menu, or via the remote network user.
• Broadcast or group network originated ESD support.
The following commands and information may be transmitted over the DeviceNet network:
• “OPEN,” “STOP,” and “CLOSE” commands
• “ESD” and “MOVE–TO” position commands
• Actuator status and alarm messages
• Four digital inputs, two digital outputs, one analog input and one analog output for user configuration
• A surge-protected and isolated communication channels
