Counter input applications
To set the module to frequency mode set the configuration code to
50
in the Set module configuration
command
Table 1-7. Counter mode settings
Counter 0
Counter 1
$AAB0 to set input mode 0
$AA1H(data) and $AA1L(data)
Non-isolated channel 0 and
threshold voltage values active
Non-isolated channel 1 and
threshold voltage values active
$AAB1 to set input mode 1
Isolated channel 0
Isolated channel 1
$AAB2 to set input mode 2
$AA1H(data) and $AA1L(data)
Non-isolated channel 0 and
threshold voltage values active
Isolated channel 1
$AAB3 to set input mode 3
$AA1H(data) and $AA1L(data)
Isolated channel 0
Non-isolated channel 1 and
threshold voltage values active
Note:
The threshold voltage value commands $AA1H(data) and $AA1L(data) are effective for non-isolated inputs
only.
