DeviceNet communication loss is not detected by the actuator. Appropriate monitoring is recommended
on DCS side.
DeviceNet according to IEC 61158 and IEC 61784-1
Topology with one trunk and optional spurs
DeviceNet power supply and DeviceNet data signals within one cable
Coupling and uncoupling of devices during operation without affecting other devices is possible
Twisted, shielded copper cable with one wire pair for signal transmission and one wire pair for DeviceNet
power supply
Based on the data transmission with CAN telegrams
