Page 87: Safety Input Function
Safety Input Function This function safely inputs external signals. This function cannot be used in any modes other than the safety operation mode. All the safety remote inputs (SA\X) are off in any modes other than the safety operation mode. Safety input wiring selection function This function is used to select double wiring or single wiring of the input wiring.
Page 88 Single wiring function This function can connect input devices with single wiring. Safety remote I/O module • To satisfy SIL3, Category 4 and PL e, use the double wiring function. • Systems using single wiring do not comply with SIL3 or Category 4 PL e, although the wiring can be used for input using safety devices.

(2) When the double inputs are on (X0 and X1 are on), SA\X0 and SA\X1 turn on.
Page 90: Safety Input Response Time Setting Function
Safety input response time setting function The safety input response time setting function is used to set the filter time to reduce incorrect inputs caused by noise in input signals. The longer the input response time is, the higher tolerance for chattering and noise the module has. But the response to input signals becomes slower.
Page 91: Safety Output Function
Safety Output Function This function safely outputs signals. This function cannot be used in any modes other than the safety operation mode. All the safety remote outputs (SA\Y) are off in any modes other than the safety operation mode. Safety output wiring selection function This function is used to select double wiring or single wiring of the output wiring.
Page 92 Single wiring function This function can connect output devices with single wiring. IO24V Load External power supply Safety remote I/O module IO24G COM- • To satisfy SIL3, Category 4 and PL e, use the double wiring function. • Systems using single wiring do not comply with SIL3 or Category 4 PL e, although the wiring can be used for output using safety devices.
Page 93 Combination of double outputs Both terminals of double outputs are turned on only when both safety remote outputs (SA\Y) are on. The safety remote I/O module evaluates the logic of safety remote outputs (SA\Y) and determines the state of the output terminals. The following table lists the correspondence between each state of safety remote output (SA\Y) and output terminal for double outputs.
Page 94: Number Of Safety Output On Times Integration Function
Number of safety output ON times integration function This function counts the number of ON times of each output point within the range of 0 to 2147483647. The integration value remains even though the output module is powered off. Whether to enable or disable the function can be set for each output point from the module parameter setting window of the engineering tool or the program.
Page 95: Input Diagnostic Function
Input Diagnostic Function Double input discrepancy detection function This function discriminates failures by monitoring the discrepancy state of doubled safety remote inputs (SA\X). Double input discrepancy detection ■Double input discrepancy detection (with discrepancy detection time specified) If "Double input discrepancy detection setting" is set to "0: Detect" and "Double input discrepancy detection type" is set to "0: Discrepancy detection time specified"...
Page 96 ■Double input discrepancy detection (with discrepancy detection time not specified) When "Double input discrepancy detection setting" is set to "0: Detect" and "Double input discrepancy detection type" is set to "1: Discrepancy detection time not specified" from the "Parameter Processing of Device Station" window, no input error occurs even though the discrepancy state of double inputs continues.
Page 97 • When a double input discrepancy detection error occurs When the discrepancy (ON/OFF or OFF/ON) state of input terminals continues for longer than 500ms after changed from ON/ ON state, the double input discrepancy is detected and the double input discrepancy detection state is applied.

Page 199: Appendix 5 Emc, Low Voltage, And Machinery Directives
Appendix 5 EMC, Low Voltage, and Machinery Directives In each country, laws and regulations concerning electromagnetic compatibility (EMC) and electrical safety are enacted. For the products sold in the European countries, compliance with the EU's EMC Directive has been a legal obligation as EMC regulation since 1996, as well as the EU's Low Voltage Directive as electrical safety regulation since 1997.
Page 200 The leakage of radio waves can be suppressed by directly applying an EMI gasket on the paint surface. The tests were conducted by Mitsubishi Electric Corporation using a control panel having damping characteristics of 37dB (maximum) and 30dB (average) (measured at 3m distance, 30 to 300MHz).
Page 201 Cables Use a shielded cable for a cable extended out of the control panel such as an I/O signal line (including a common line) and cable for communications. If a shielded cable is not used or not grounded properly, the noise immunity will not meet the requirement. ■Cables for the CC-Link IE Field Network The precautions for using CC-Link IE Field Network cables are described below.
Page 202 Others ■Ferrite core A ferrite core is effective for reducing radiated noise in the 30MHz to 100MHz frequency band. It is recommended to install a ferrite core if a shielded cable extended out of the control panel does not provide sufficient shielding effects.
Page 203: Measures To Comply With The Low Voltage Directive
Measures to comply with the Low Voltage Directive Module The module operates at the rated voltage of 24VDC. The Low Voltage Directive is not applied to the modules that operate at the rated voltage of less than 50VAC and 75VDC. External wiring ■24VDC external power supply To connect to the module, use the power supply that meets the following conditions:...
Page 204: Measures To Comply With The Machinery Directive
Measures to comply with the Machinery Directive The Machinery Directive (2006/42/EC) requires that machinery satisfy the three pillars of safety: mechanical safety, electrical safety, and worker safety. This product is suitable for establishing safety functions for general industrial machinery and complies with the Machinery Directive (2006/42/EC).
