Data Parameters

Table 33: 0x0001 (1) Production Data

Size	Description
Varies	This list contains the concatenated values of QCPort Parameters specified in QCPort Configuration Parameter
	0x800C, Production List.
Table 34: 0x0002 (2) Consumption Data
Size	Description
Varies	This list contains the concatenated values of QCPort Parameters specified in QCPort Configuration Parameter
	0x800D, Consumption List.
Table 35: 0x0003 (3) QCPort Status
Size	Description
1 Byte	This parameter indicates the QCPort fault condition that caused a device to enter the Fault Mode, as indicated
	below:
	0x00 — No QCPort Fault
	0x01 — Node ID Conflict
	0x02 — Invalid Node ID in Master/Slave
	0x03 — Physical Node ID does not match actual ID
	0x04 — Duplicate configured nodes online
	0x05 — Dynamic Node ID overflow
	0x06 — Invalid baud rate selected
	0x07 — Errant Device fault
	0x08 — Problem with data in non-volatile memory
Table 36: 0x0004 (4) Application Status (Available in I/O As Control Elements)
Size	Description
2 Bytes	This parameter indicates the application status of the QCPort device. It reports the most recent fault or warning.
	If there have been no faults or warnings, it reports 0. Reset clears this parameter.
Table 37: 0x0005 (5) Discrete Data Input (Available in I/O As Control Elements)
Size	Description
n Bytes	A series of BYTES that represent discrete digital inputs on a device. This parameter is used in any input module
	having discrete inputs.
	The least significant bit of byte 0 corresponds to input point 0.
Table 38: 0x0006 (6) Discrete Data Output (Available in I/O As Control Elements)
Size	Description
n Bytes	A series of BYTES representing the state of the outputs of a discrete output device. This parameter is used in
	any module having discrete outputs. The least significant bit of byte 0 corresponds to output point 0.
	Parameter 0x8023, “Output Comm Loss Behavior” is used in conjunction with this parameter.
Table 39: 0x006B (107) Analog Input Status (Available in I/O As Control Elements)
Size	Description
n Bytes	This provides channel status for the analog inputs.
	U = Under Range
	O = Over Range
		Byte	Bit 7	Bit 6	Bit 5 *	Bit 4 *	Bit 3	Bit 2	Bit 1 *	Bit 0 *
		0			O1	U1			O0	U0
		1			O3	U3			O2	U2

* Setting the bit from “0” to “1” indicates that the condition is true.
