Host Mode Enable
Host Mode Enable allows the user to decide where the control will occur from the DeviceNet network. Host Mode Enable allows the user to ignore hardwire inputs. Conversely,
Enabling the “Host Mode” gives the host (DeviceNet Master) exclusive control of the following parameters:
Index Select and Index Initiate Jog +, Jog
Define Home
Brake Control and Release
All other functions will be logically OR’ed with hardwire and Modbus inputs when in Host mode.
Host mode is useful when access to the hardwire I/O needs to be switched from “DeviceNet only” to “DeviceNet I/O or Hardware I/O.”
