Explanation
1.
This instruction is available for PLC with FW V1.08.00 or later. For ISPSoft, we recommend using software version
3.12 and above.
2.
The DPUCNT instruction supports AS02PU module only. When En setting is set to ON, this instruction would be
effective. Once the setting changes to OFF, the counting would be stopped immediately.
3.
Module sets the serial number of modules at the right of the PLC. The first one is number 1, the second one is
number 2 and so on. Whatever modules at the right of the PLC must be numbered. The maximum number is 32.
The instruction is exclusive to the PU modules at the right of the PLC and is not applicable to the PU modules at the
right of the remote module. If the specified module is not a PU module, the error flag Error will change to ON.
4.
InMode sets the input mode of the encoder source and the frequency multiplication for counting.
See the explanation of InMode value in the following table.
Note: Phase A leads phase B, indicating counting in the positive direction.
Phase B leads phase A, indicating counting in the negative direction

5.
Period is the setting value of a cycle time for capturing the frequency within the range of 10ms ~ 1000ms. If the
setting value exceeds the range, the maximum value or minimum value will be automatically taken as the setting
value by the PLC.

Input mode; set as the following values, otherwise the module will use the defaults to run.
Reserved
Onefold frequency A/B phase input
Twofold frequency A/B phase input
Reserved
Fourfold frequency A/B phase input (default)
Pulse + directional input (A+/A-: pulse input; B+/B-: directional input)
Phase B ON: counting in the negative direction
Phase B OFF: counting in the positive direction
Phase A: counting is started by rising-edge triggered.
Pulse + directional input (A+/A-: pulse input; B+/B-: directional input)
Phase B ON: counting in the positive direction
Phase B OFF: counting in the negative direction
Phase A: counting is started by rising-edge triggered.
Single phase pulse input (A+/A-: pulse input)
Phase A: counting is started by rising-edge triggered.
