1: Open circuit detection for input device is a function only available for digital input unit with disconnection detection (EX600-DXPC1,
EX600-DXNC1).
2: 2-wire type input equipment cannot be correctly detected if its leakage current is 0.5 mA or less while the equipment is in the OFF
state (reed sensor, etc.).
Ensure that all input equipment used has a leakage current above 0.5 mA in the OFF state.
3-wire type input equipment cannot be correctly detected if its current consumption is 0.5 mA or less.
The open circuit of input signals cannot be detected.
3: The count is memorized every hour. When the power supply is turned on again, counting starts from the last value memorized.
4: Times for setting is set value × 1000 times.
5: Refer to “Counter value” of Index 50x3:0 in the CoE object dictionary (page 110) or the Web server (page 121) for the clear method.
