ET-8CNT Usage Tips
|
¢ |
Each input channel may be individually configured for any of these functions: |
|
|
Simple pulse accumulation (counting) |
|
|
Direct rate measurement (for flow rate, conveyor speed, etc) |
|
|
Up/down counting (32-bit signed result) |
|
|
Position (connection to a quadrature encoder) |
|
|
Discrete input (don’t waste extra channels) |
|
¢ |
Run input signals in twisted pairs of wires for best noise immunity. For best differential noise rejection, do not connect screw terminals together at the I/O base. |
|
¢ |
Unused input channels can be configured as discrete inputs. |
|
¢ |
Use two adjacent input channels to report both total accumulated counts and count rate. |
Note:
Up/down counting and position measurement modes require two input signals and therefore utilize two counter channels.
