Event input function

Event input function

• • Number of input points: 7 Number of input points: 7
• • Counts pulses by judging a pulse output from external equipment as an input. Counts pulses by judging a pulse output from external equipment as an input.
• • Calculates power original unit by dividing integrated power amount by pulse input count. Calculates power original unit by dividing integrated power amount by pulse input count.
• • Measures pulse input ON time. Measures pulse input ON time.
• • Classifies energies according to event input conditions. (3-STATE function) Classifies energies according to event input conditions. (3-STATE function)
* Power original unit is used for measuring tact power of product lines. Pulse input ON time * Power original unit is used for measuring tact power of product lines. Pulse input ON time
is used for calculating operation time of equipment. is used for calculating operation time of equipment.

• Performs switching between input without voltage and with voltage in event inputs 1 to 7.
• When using this function for relays, etc., take into account chattering, etc. that will occur.
On resistance: 1 kΩ or less, Off resistance: 100 kΩ or more
• With Voltage (PNP) means an input for switching ON/OFF by applying voltage to the event
input terminal.
H level: 4.75 to 30 VDC, L level: 0 to 2 VDC
• Setting range: PNP, NPN (Initial value: PNP)

Event input N-O/N-C input mode setting

PMU1A PMU2A
(Electric (Power
power) two-system)
× ×
• Performs switching between Normally open and Normally closed in the event input.
• Normally open (N-O) judges an open (release) state as event OFF, and a closed
(continuity) state as event ON.
On the other hand, Normally closed (N-C) judges a closed (continuity) state as event ON,
and an open (release) state as event OFF.
• Setting range
