Network topologies*25
*25: CC-Link IE Field Network Basic supports star topology only.
Cyclic transmission
In cyclic transmission, data is transmitted periodically using link devices. Under CC‑Link IE Field and Controller networks, some differences exist as described in this section.
CC-Link IE Field Network*26
One-to-one communication is possible between the master and device stations. The status of link devices (RY, RWw) within the master station are transmitted to an external device connected to a device station. Likewise, the status of external devices is transmitted to the master station link devices (RX, RWr) via the device station.
In the case of local stations, the status of the master station link devices (RY, RWw) is relayed to all local station link devices (RX, RWr) on the network. When an input from a device or local station is executed, the device station link devices (RX, RWr) status and local station link devices (RY, RWw) status are stored in the master station link device (RX, RWr), along with other local station link devices (RY, RWw). As a result, all local stations possess the data of other device stations, similar to the master station.
*26: The data is transmitted in the same method on CC-Link IE Field Network Basic. Note that communication is made between the master station and the device stations only. No local stations are available on the CC-Link IE Field Basic.
Output from the master station
① In the master station, devices of the CPU module turn ON.
② In the master station, the status of the CPU module devices are stored in the link devices (RY, RWw) by link refresh.
③ The status of the master station link devices (RY, RWw) are then stored in the device station link devices (RY, RWw), and in the local station link devices (RX, RWr) by link scan.
④ The status of the local station link devices (RX, RWr) are stored in the CPU module devices.
Input from the device or local station
⑤ In the local station, devices of the CPU module turn ON.
⑥ In the local station, the status of the CPU module devices are stored in its own station link devices (RY, RWw) transmission area.
⑦ The status of the device station link devices (RX, RWr), and the local station link devices (RY, RWw) are stored in the master station link devices (RX, RWr) by link scan.
⑧ The status of the master station link devices (RX, RWr) are stored in the CPU module devices by link refresh.
CC-Link IE Controller Network
Communications using link relays (LB) and link registers (LW)
This function allows each station to write data to its own send range of a link device (LB, LW) to send them to all other stations on the network. The status data of the control station link devices (LB, LW) are stored in the link devices (LB, LW) of each normal station. Likewise, the status of the normal station link devices (LB, LW) is stored in link devices (LB, LW) of the control and other normal stations.
① In the transmitting station, the CPU module devices turn ON.
② In the transmitting station, the CPU module devices status are stored in the link devices (LB, LW) of the CC‑Link IE Controller Network supporting module by link refresh.
③ The status of the link devices (LB, LW) in the transmitting station are sent to the link devices (LB, LW) of the CC‑Link IE Controller Network supporting module in the receiving station by link scan.
④ In the receiving station, the status of the link devices (LB, LW) are stored in the CPU module devices.
Transmissions using link inputs (LX) and link outputs (LY)
An I/O master station, which controls link inputs (LX) and link outputs (LY), and another station make one to one communication. LX is the input data transmitted between stations in a block, and LY is the output data transmitted from the I/O master station in a block. The control or normal station can be an I/O master station, and up to two I/O master stations (block 1 and block 2) can be used per network.
Transient transmission
This function allows communications with other stations when a request is made by a method such as a dedicated instruction and engineering software. Communications with different networks is also possible.
