(b) Transient transmission range of the link dedicated instruction
• Single network system
It is possible to communicate with all stations on the network.
• Multiple network system
Communications can be made with stations up to eight networks apart by setting routing parameters.
( Page 92, Section 7.7)
● Only one master/local module can be mounted on a safety base unit. Therefore, a safety programmable controller cannot
relay more than one CC-Link IE Field Network. To relay more than one CC-Link IE Field Network systems, use a
standard programmable controller.
● Use the communication test in CC-Link IE Field Network diagnostics to check whether the routing of transient
transmission from the own station to the destination is correctly performed or not.
