DeviceNet Communication Adapter

1.2.1Exec. V. 1.10 vs. V. 1.20

Exec. V. 1.20 changed the behavior of certain I/O bases if a field side fault occurred. This change affects the following bases.

H170 ADM 350 10

H170 ADM 350 11

H170 ADM 390 10

H170 ADM 370 10

The following table describes the differences between the two versions in more detail. Refer to the TSX Momentum I/O Base User Guide (870 USE 002 00) for module specifications.

Table 3 Exec. V. 1.10 vs. V. 1.20

Firmware	Module	Action
	170 ADM 350 10	If one of the field side outputs faults
		(shorts out), the host will read all inputs
	170 ADM 350 11
		as zeros, regardless of the input signal
	170 ADM 370 10
		state.
		If one of the field side outputs faults
Version 1.10		(shorts out), the host will read all inputs
		as zeros, regardless of the input signal
	170 ADM 390 10	state.
		If an open condition exists (unconnected)
		on any of the input points, the host will
		read all inputs as zeros, regardless of the
		input signal state.
	170 ADM 350 10	If one of the field side outputs faults
	170 ADM 350 11	(shorts out), the host will continue to read
	170 ADM 370 10	the inputs normally.
		If one of the field side outputs faults
Version 1.20		(shorts out), the host will continue to read
		the inputs normally.
	170 ADM 390 10	If an open condition exists (unconnected)
		on any of the input points, the host will
		read
		H open inputs as zero (fault) and
		H remaining non–faulted inputs normally.
