AMX NXP-CPI16 manual Programming, Levels, Status on Mode Channel Assignment

Programming

Programming

There are two modes of Channel Assignments: Discrete Output and Default Mode. Both modes are set using the ‘STATUS-ON’ and ‘STATUS-OFF’ commands. Discrete Output mode should be used if channel status feedback for the outputs needs to be separate from the inputs. The tables below provide channel assignment information on both modes. For more information, refer to the Send_Commands section on page 6.

Status ON Mode Channel Assignment

I/O		Corresponding Channel
		Assignment
Inputs 1 - 8		Channels 1	- 8 (On/Push/Off/Release)
Outputs 1	- 8	Channels 9	- 16 (On/Off only)
Inputs 9 - 16		Channels 17 - 24		(On/Push/Off/Release)
Outputs 9	- 16	Channels 25 - 32		(On/Off only)

Status OFF Mode Channel Assignment

I/O		Corresponding Channel
		Assignment
Inputs 1 - 8		Channels 1	- 8	(Push/Release only)
Outputs 1	- 8	Channels 1	- 8	(On/Off only)
Inputs 9 - 16		Channels 9	- 16		(Push/Release only)
Outputs 9	- 16	Channels 9	- 16		(On/Off only)

Levels

By default all levels have a data type of byte (8-bits), which gives a range of 0-255 for the Level Value. The ‘LVL_SZ’ Send_Command sets the size of the value for levels 1 - 4. It is important that the variable in any SEND_LEVEL command and CREATE_LEVEL statement in the NetLinx program match the data type selected by the ‘LVL_SZ’ Send_Command. Incorrect levels may occur if the data types do not match.

The input and output Level values will not be sent until a ’LEVON’ command message is received by the CPI16. A transmission of levels will cease after the receipt of a ’LEVOFF’ command.

The values of Levels 1 and 2 (quadrature inputs) will be sent whenever the input changes.
