When used for DeviceNet, the fieldbus port has the following characteristics.
• Baud rate: 125, 250, and 500 kbps
• MAC ID: 0 to 63
• Vendor ID: 928
• Product Code: 0x4D47
• Message types: poll, and explicit messaging
The ODVA cable assembly length (0.4 metre) must be considered when calculating the
network drop length budget to the node.
The DeviceNet port uses external voltage to power the electronics. The figures below show
the configuration of the the comms board option/power supply switch.
DeviceNet supports external power only.
