[Design Precautions] WARNING ● For the operating status of each station after a communication failure, refer to Page 136, Section 8.2.6 in this manual. Incorrect output or malfunction due to a communication failure may result in an accident. ● When connecting a peripheral with the CPU module or connecting an external device, such as 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.
Page 5
[Security Precautions] WARNING ● To maintain the security (confidentiality, integrity, and availability) of the programmable controller and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other cyberattacks from external devices via the network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.
Page 6
[Wiring Precautions] CAUTION ● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when a terminal block screw comes loose, resulting in failure. ● Do not install the control lines or communication cables together with the main circuit lines or power cables.
Page 7
[Startup and Maintenance Precautions] CAUTION ● Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire. ● Shut off the external power supply (all phases) used in the system before mounting or removing a module.

(3) Local station communication The local station is a station having a programmable controller CPU and the ability to communicate with the master and other local stations. Communication between a master station and a local station uses two types of transmission methods: cyclic transmission and transient transmission (refer to Page 118, Section 8.1.3).
Page 23
CHAPTER 1 FEATURES (4) Intelligent device station communication The intelligent device station is a station that can handle bit and word data. Communication between a master station and an intelligent device station uses two types of transmission methods: cyclic transmission and transient transmission (refer to Page 124, Section 8.1.4).

8.3.4 Reserved station function This function prevents device stations that are not actually connected (but to be connected in the future) from being treated as "data link faulty stations" by the master station and local stations. When the master station is placed in the remote net ver.2 mode, points for reserved stations can be set to 0. Use GX Works2 to set 0 points for reserved stations.
CHAPTER 8 FUNCTIONS 8.3.5 Error invalid station setting function This function prevents device stations that are powered off in the system configuration from being treated as "data link faulty stations" by the master station and local stations, using the network parameter settings. Note that if a station is set as an error invalid station, problems occurring in that station can no longer be detected.
8.3.6 Temporary error invalid station setting function This function allows the replacement of modules while online, without error detection. Also, this function prevents device stations, which are turned off in the system configuration, from being treated as "data link faulty stations" temporarily. (1) Setting method Set the [Diagnostics] [CC-Link Diagnostics] using GX Works2.
Page 183
CHAPTER 8 FUNCTIONS (2) Precautions (a) Precautions when temporary error invalid station setting is executed • Do not write to buffer memory addresses 5E0 , and 603 to 607 • Do not execute at one time by programs and other peripherals. If executed at one time, temporary error invalid station setting may not operate normally.
8.3.7 Scan synchronous function This function selects whether to synchronize or not the link scan with the sequence scan. (1) Synchronous mode Performs data linking using the scan that is synchronized with the program. (The sequence scan and link scan start at the same time.) In the synchronous mode, the link scan interval becomes longer when the sequence scan takes long because the link scan is synchronized with the sequence scan.
Page 185
CHAPTER 8 FUNCTIONS (4) Data flows in synchronous and asynchronous modes The data flows in both the synchronous and asynchronous modes are explained using examples of communications between the master station and remote I/O stations. Even if latched device (listed in "CPU side device" in the table below) data are cleared to 0 by a program at reset of the CPU module or at power off and on, the latched data may be output depending on the timing of link scan and link refresh.

8.3.8 Data link stop/restart This function stops and restarts local data links. If the data link is stopped, programs can be efficiently debugged, since other stations data are not received and host station data are not sent. If the data link of the master station is stopped, the data link of the entire system stops. (1) Setting method Set the [Diagnostics] [CC-Link Diagnostics] using GX Works2.

8.3.9 Remote I/O station points setting The points of each remote I/O station can be set to 8, 16 or 32 points. This saves the refresh device points of the programmable controller CPU and link refresh time. The remote I/O station points setting can be used in the remote net ver. 2 mode only. For parameter setting, use GX Works2.
Page 191
CHAPTER 8 FUNCTIONS [Setting method] Use GX Works2 to set "Station Information Setting" - "Remote Station Points" in the network parameter setting. (Refer Page 83, Section 7.3.2 (2).) (1) Precautions for setting the remote I/O station points The number of parameter-set remote I/O station points should be equal to or greater than the number of I/O points of the mounted remote I/O stations.
8.3.10 Master station duplication error cancel function This function cancels a master station duplication error without turning the power supply off to on, or without resetting the programmable controller CPU, if a master station duplication error is detected.
