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. 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-NM1 or R3-NE1 of firmware version V2.00 or later. Count preset is not available for other combination.
Notice that this function is not available in the same time as count preset by host PC/PLC.

FUNCTIONS
■
MANUAL COUNT RESET
1) Remove Network Module or its cables and interrupt communication with other devices.
2) Turn ON the Count Reset SW.
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.
The RUN LED starts blinking at the same time.
5) After the green LED is confirmed, turn the power supply off.
6) Turn OFF the Count Reset SW.
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.
■
REMOTE COUNT RESET INPUT
With the Count Reset Input SW (SW3-3) turned ON, the Pi 16 pulse input can be used to remotely reset the count values.
SW3-3 = OFF: Pi 16 is used as a pulse input.
SW3-3 = ON: Pi 16 is used to reset the count values for the Pi 1 through Pi 15. One pulse supplied at the Pi 16 will be recognized as a reset signal.
■
REMOTE COUNT RESET OPERATION
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.
