SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the user's manual for the CPU module used.
Page 4 [Design Precautions] WARNING ● When connecting GX Works2 with the CPU module or connecting a personal computer with an intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding.
Page 5 [Design Precautions] CAUTION ● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise. [Installation Precautions] WARNING ●...
Page 6 [Wiring Precautions] CAUTION ● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction. ● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring.
Page 7 [Startup and Maintenance Precautions] CAUTION ● Before performing online operations (especially, program modification, forced output, and operating status change) for the running CPU module on another station from GX Works2 over CC-Link IE Field Network, read relevant manuals carefully and ensure the safety. Improper operation may damage machines or cause accidents.

Page 22: Chapter 1 Cc-Link Ie Field Network
CHAPTER 1 CC-LINK IE FIELD NETWORK CC-Link IE Field Network CC-Link IE Field Network is a high-speed and large-capacity open field network that is based on Ethernet technology (1000BASE-T). (1) Data communication High-speed and large-capacity data communication is available between a master station and slave stations on CC-Link IE Field Network.
Page 23 CHAPTER 1 CC-LINK IE FIELD NETWORK (2) 1Gbps communication speed 1Gbps communication speed allows high-speed communication. Also, the takt time can be reduced due to the improved performance of communication response. (3) Use of Ethernet cable A 1000BASE-T-compliant Ethernet is used for the connection interface. The wiring cost can be reduced because 1000BASE-T-compliant Ethernet cables are commercially available.
Page 24: Master/Local Modules
Master/Local Modules A master/local module is used to connect a MELSEC-Q series programmable controller to CC-Link IE Field Network. The module works as a master station or a local station on CC-Link IE Field Network. (1) High-speed periodic communication (cyclic transmission) Since transmission delay time is short, delay caused during communication does not need to be considered (if the link scan time of each master/local module is shorter than the scan time of the CPU module).
Page 25 CHAPTER 1 CC-LINK IE FIELD NETWORK (2) Irregular communications with the programmable controller on another station (transient transmission) (a) Reading or writing data A master/local module can access programmable controllers on other stations by dedicated instructions. Page 236, Section 10.1) Seamless access of programmable controllers on other networks such as Ethernet, CC-Link IE Controller Network, MELSECNET/H, and MELSECNET/10 is also possible.
Page 26 (3) Settings and diagnostics by GX Works2 (a) Setting parameters Parameters for master/local modules can be set using GX Works2. Creating parameter setting programs is not necessary. ( Page 81, CHAPTER 7) Parameters for master/local modules can be also set by a program. ( Page 359, Section 10.17) When set by a program, the parameters of the master station can be changed while the CPU module is running.
Page 27 CHAPTER 1 CC-LINK IE FIELD NETWORK (b) Checking CC-Link IE Field Network status graphically The CC-Link IE Field Network status can be checked using GX Works2. Error locations, error causes, and event history are displayed on the window. This allows the system to quickly recover from errors. Page 206, CHAPTER 9)
Page 28 (c) Seamless access to other networks GX Works2 can seamlessly access (test or monitor) systems composed of other networks through CC-Link IE Field Network. The accessible networks are Ethernet, CC-Link IE Controller Network, MELSECNET/H, MELSECNET/10, and CC-Link. Seamless access enables the user to change the access target without modifying the connection between the personal computer and programmable controller.
Page 29 CHAPTER 1 CC-LINK IE FIELD NETWORK (4) Adding and replacing CC-Link IE Field Network devices without stopping the system (a) Adding CC-Link IE Field Network devices CC-Link IE Field Network devices whose parameters have not been set can be added without powering off the system.
Page 30 (c) Automatic return when disconnected stations recover When the station disconnected from the network due to a data link error recovers, it automatically returns to the network and restarts data link. Master station Slave station Master station Slave station Station No.0 Station No.1 Station No.0 Station No.1...
Page 31 CHAPTER 1 CC-LINK IE FIELD NETWORK (5) Seamless communications with Ethernet devices Communications using the specified IP address can be performed over CC-Link IE Field Network. For example, a personal computer can communicate with the FTP server. With this function, two networks of CC-Link IE Field Network and Ethernet are not required, resulting in reduced wiring cost.
Page 32 (6) Continuing data link even if the master station is disconnected Connecting the master station and submaster station on the same network allows the submaster station to continue controlling slave stations instead of the master station even if the master station is disconnected. Using this function prevents the entire network from going down due to disconnection of the master station.
