MODEL: R3-PA16

R3-PA16 SPECIFICATIONS

ES-8389 Rev.12 Page 2/6

https://www.m-system.co.jp/

INPUT SPECIFICATIONS

Number of input: 16 points

Input resistance: 6 kΩ

Common: Negative commons, all points

Maximum frequency: 100 Hz (ON/OFF time ≥ 5 msec.)

This unit is designed to be able to accept a frequency up to

100 Hz, however, ‘chattering’ contact must be avoided for

accurate measuring of such high frequency. Use mercury

relays or similar ones that do not cause any chattering.

Totalized pulse range: 1 – 10000 (‘0’ at reset)

Max. pulse range selectable from 1 to 65535 using the

R3CON PC Configurator Software. Refer to the R3CON Users

Manual for detailed information.

Count at overflow: Reset and restart at ‘1.’

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.

■ COUNT RESET FROM HOST PC/PLC

Refer to “COUNTER SETTING FROM HOST PC/PLC” section

hereafter.
