Johnson Controls XP-910x, XT-9100 appendix Analog Output Configuration, Counter Prescaler

DI: Counter Prescaler

DI Notes

Analog Output Configuration

The digital input transitions of XP1 are counted as follows:

	Digital		Prescale	Count	Pulse
	Input		PCn	Transition	Counter
	DIn				CNTRn
(RI.09)		(RI.48-55)			(RI.32-39)

Figure 3: Counter Prescaler

A count transition occurs when the number of positive transitions of the digital input (DIn) equals the value of the prescaler (PCn). The Pulse Counter (CNTn) counts the count transitions (n = 1-8).

Note: Counters are only available in the XP1 location.

Via the GX Tool

Select XTn, DIn, then Data. At the “Prescaler (counts)” field, enter from 1 to 255. When the XT-9100 is connected to a DX-9100 Controller the total counts can be read on the DX-9100 front panel.

Via the SX Tool

Enter the prescaler at Item PCn (RI. 48-55) within the range 1-255.

1.When the XT-9100 is connected to a DX-9100 Controller, you can view the DI status and counter values from the DX-9100 front panel. See the Display Panel and Keypads section in the DX-9100 Extended Digital Controller Technical Bulletin (LIT-6364020).

2.The status of the digital inputs can be seen at Item DIS1 (RI.09), bits X1-X8, and Item DIS2 (RI.10), bits X1-X8.

Each analog output is defined and configured by the following parameters:

∙Tag name (GX-9100 only)

∙Output type

When the XT is connected to a DX-9100 Controller, the following parameters are defined in the DX-9100 for the analog output:

∙Source

∙Range
