1.2 Master/Local Modules
A master/local module is used to connect a safety programmable controller to CC-Link IE Field Network.
The module is used being mounted on a safety base unit.
The module can be used as the following stations on CC-Link IE Field Network.
• Master station (safety station)
• Local station (safety station)
• Local station (standard station)
(1) Communication that ensures safety (safety communication)
Data communication ensuring high safety (safety communication) can be performed.
Data is communicated after a safety connection is established between safety stations on the same network.
( Page 96, Section 8.1)
(a) Safety stations added on CC-Link IE Field Network
Safety programmable controllers and standard programmable controllers can co-exist on the same network. A
network system with high safety can be easily established by adding safety stations on an existing CC-Link IE
Field Network. ( Page 47, Section 5.1.1)
The master/local module has acquired certification of the highest safety level (SIL3 of IEC 61508, Category 4 of EN 654-1,
and Category 4 performance level
"e" of EN ISO 13849-1) applicable to programmable controllers.
