EtherCAT MainDevice Target State

Type:	Communications Register
Address:	RMC75: n/a RMC150: n/a RMC200: %MD119.0
System Tag:	_ECAT.TargetState
How to Find:	Address Selection Tool ® EtherCAT ® Status
Data Type:	DINT

Description

This register specifies the network state that is currently being targeted by the EtherCAT state machine. The RMC MainDevice will attempt to bring the network state to the Target State, stepping the network one state at a time toward Operational, and each state will take some time to achieve. Network faults may prevent reaching the target state.

The current network state is given by the EtherCAT Current MainDevice State register. The EtherCAT Bus State provides more detailed information about the state of the EtherCAT network.

This register is initialized to the Startup State when the RMC powers up and each time the network is restarted or reconfigured. The Startup State may be set in the EtherCAT Editor, on the MainDevice General tab.

Writing to this register will change the desired final MainDevice state. This register is not saved to flash.

Value	Description
1	Init The network is initialized, but PDO and SDO communication is not possible yet.
2	Pre-Op The network can communicate SDOs, but PDOs are not possible yet.
4	Safe-Op Both PDO and SDO communication is possible on the network, but PDO outputs are disabled.
8	Op The network is fully operational.
