Note
:
• Count reset by host PC/PLC:
Available with this unit and the above mentioned interface modules of firmware version V2.00 or later, except R3-NFx (R3-NM3: Firmware version V1.00 or later). Notice that Count reset by host PC/PLC via R3-NFx or interface module of previous versions of firmware is unable.
• Count preset by host PC/PLC:
It is only available in combination with this unit displayed 'SW3-4 RESET/PRESET' on the right side panel and the interface module R3-NMx or R3-NE1 of firmware version V2.00 or later. Count preset is not available for other combination (R3-NM3: Firmware version V1.00 or later).
Notice that this function is not available in the same time as count preset by host PC/PLC.
• In the FL-net Configuration Builder software (model: R3-NFLBLD), the number of channel for this module is displayed as 16 because data has 8 channels x 2 words.

COUNT RESET
There are three different ways to reset count value.
■ COUNT RESET WITH DIP SW
1) Remove Network Module or its cables and interrupt communication with other devices.
2) Turn ON the Count Reset SW (DIP SW3-1) on R3-PA8 module.
3) Return the module to the base and turn the power supply on.
4) ERR LED turns on and the module starts resetting its counter. When the resetting is complete, the LED turns to green. DO NOT remove the power while the red LED is on.
5) After confirming that ERR LED is green, turn the power supply off.
6) Turn OFF the Count Reset SW (DIP SW3-1).
7) Return the Network module onto the base and turn the power supply on.
Note: Count Reset SW must be turned OFF after this procedure because the module does not start counting with ON state. Even when the count overflow set value is 1, the counter is reset to 0.
■ COUNT RESET WITH RESET SIGNAL
With the Count Reset Input SW (DIP SW3-3) turned ON, the count reset signal value becomes effective.
SW3-3 = OFF: invalid
SW3-3 = ON: valid
One pulse supplied at the Count reset input terminal will be recognized as a reset signal.
1) ERR LED turns on (red color) when the reset signal is received.
2) In 1 second, the module starts resetting its counter. When the resetting is complete, the LED turns to green.
3) After 1 second, ERR LED turns back to the state before the reset signal has been received.
Note: Reset signals received while the module is processing (1) through (3) are ignored. Even when the count overflow set value is 1, the counter is reset to 0.
