*Bit 5 and 6 of the instance 21 byte 0 are defined as follows.

Bit 5 (Net Ctrl)	When “1” is set, bits 0 (Run forward) and 1 (Run reverse) of byte 0 are enabled.
	When “0” is set, Run/Stop is according to setup of the parameter cmod.
Bit 6 (Net Ref)	When “1” is set, bytes 2 and 3 are enabled.
	When “0” is set, Drive Reference Speed is according to setup of the parameter fmod.

**Bit 5, 6, and 7 of the instance 71 byte 0 are defined as follows.

Bit 5	(Ctrl from Net)	When RUN/STOP command from DeviceNet is enabled, “1” is set.
Bit 6	(Ref from Net)	When frequency command from DeviceNet is enabled, “1” is set.
Bit 7	(At reference)	When output frequency becomes the same as frequency command, “1” is set.

***Drive Status is same as the Control Supervisor class State attribute (refer to section 3.7.2). 1 (= BN: 00000001): Startup

2 (= BN: 00000010): Not Ready

3 (= BN: 00000011): Ready

4 (= BN: 00000100): Enabled

5 (= BN: 00000101): Stopping

6 (= BN: 00000110): Fault Stop

7 (= BN: 00000111): Faulted
