DEVICENET PROTOCOL CGCOMMUNICATIONS GUIDE
The commands are executed continuously as long as the control bits are high. When two
or more commands are executed simultaneously, only one will be executed. The command
hierarchy for execution is given below.
1. Motor stop
2. Fault reset
3. Motor start
Note
The corresponding command bit should be high for more than 500 ms to execute the
command.
The Polled input bytes can be selected from two predefined groups of parameters or one
group of user-defined parameters with the “DeviceNet Input Poll Data Group” setpoint. The
list of parameters in each group is given below:
