OVERVIEW
Our safety programmable controllers obtained safety approval at the highest safety level that the programmable controller can
obtain (ISO13849-1: 2006 Category 4 and PLe, IEC62061: 2012 SIL3, and IEC61508: 2010 SIL3).
The customer can use safety programmable controllers for configuring safety station with ISO13849-1: 2006 Category 4 and
PLe, IEC62061: 2012 SIL3, and IEC61508: 2010 SIL3.
Safety control and standard control programs can be simultaneously executed under a safety CPU. Similarly, both safety and
standard communications can be executed under a network.
System configuration for safety programmable controllers is shown below:
• Mount power supply module, safety CPU, safety function module, CC-Link IE Field Network master/local module on the
main base unit.
• Connect CC-Link IE Field Network master/local module and safety remote I/O module by network.
• Connect personal computer installed engineering tools to safety CPU, when setting programs and parameters.
