Counter input applications
The counter mode type is indicated by entering 50 in the 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 value active Non-isolated channel 1 and
threshold value active
$AAB1 to set input mode 1
$AA1H(data) and $AA1L(data)
Isolated channel 0 Isolated channel 1
$AAB2 to set input mode 2
$AA1H(data) and $AA1L(data)
Non-isolated channel 0 and
threshold value active Isolated channel 1
$AAB3 to set input mode 3
$AA1H(data) and $AA1L(data)
Isolated channel 0 Non-isolated channel 1 and
threshold value active
Note:
The threshold value commands $AA1H(data) and $AA1L(data) are effective to non-isolated inputs only.
