CHAPTER 1 OVERVIEW This manual provides information on the specifications, functions, preoperational procedure, programming and troubleshooting of the QJ71GP21-SX and QJ71GP21S-SX CC-Link IE Controller Network modules (hereinafter referred to as CC-Link IE Controller Network module). When applying a program example introduced in this manual to the actual system, make sure to examine the applicability and confirm that it will not cause system control problems.
Page 23: Features
CHAPTER 1 OVERVIEW Features This section explains the features of the CC-Link IE Controller Network module. (1) Periodic communication (Cyclic transmission) ( Page 59, Section 4.1) (a) Periodical exchange of large volume of data Using link devices of the CC-Link IE Controller Network module allows periodical exchange of large volume of data between stations on the same network.
Page 24 (b) Configuration of a large-scale network system Since a large number of modules and link points can be used in one network, a large-scale network system can be constructed. Also, when expanding the network, additional stations and send points can be easily set up. The number of connectable modules per network is as follows.
Page 25 CHAPTER 1 OVERVIEW (d) Automatic data transfer between link devices and the devices of a CPU module (Link refresh) Automatic transfer is available between link devices of the CC-Link IE Controller Network module and devices of a CPU module. ( Page 69, Section 4.1.3) For the Universal model QCPU other than the Q00UJCPU, the extended link register (W) is useful for transferring link register (LW) data that exceeds the link register (W) capacity (8K points).
Page 26 (g) Group cyclic transmission Cyclic transmission can be performed only with specified stations. A Universal model QCPU can share cyclic data with stations in the same shared group. ( Page 83, Section 4.1.8) This function is useful, for example, when sharing data among all stations that integrates and controls production lines and not sharing the data with stations that controls other machines.
Page 27 CHAPTER 1 OVERVIEW (2) Irregular communication (Transient transmission) ( Page 94, Section 4.2) (a) Communications with a programmable controller on another station Using a link dedicated instruction, data can be read from or written to a programmable controller on another station.
Page 28 (c) Seamless access to different networks The programming tool can execute seamless access through CC-Link IE Controller Network, achieving testing and monitoring to a system in a different network. Accessible network types are: Ethernet, CC-Link IE Field Network, MELSECNET/H, MELSECNET/10, and CC-Link. This enables access destinations to be changed without changing the wiring between a personal computer and programmable controllers.
Page 29 CHAPTER 1 OVERVIEW (3) Seamless communication to Ethernet devices Communication using the specified IP address can be performed over CC-Link IE Controller Network. For example, a personal computer can communicate with the FTP server. With this function, two networks of CC-Link IE Controller Network and Ethernet are not required, resulting in reducing the wiring cost.
Page 30 (4) Enhanced RAS functions (a) Continuation of communications at system down of the control station Even if the control station goes down, a normal station (sub-control station) will take over the control to continue data link. ( Page 124, Section 4.4.1) Switching Control station Sub-control station...
Page 31 CHAPTER 1 OVERVIEW (d) Detection of a faulty cable A cable fault can be detected as a cause of a communication error. ( Page 127, Section 4.4.4) Communication error Control station Normal station No.1 No.2 A cable fault is detected as the cause of the communication error.
Page 32 (g) Connection of an external power supply The external power can be directly supplied to the CC-Link IE Controller Network module with external power supply function. ( Page 134, Section 4.4.7) Even if a CPU module power goes down in a network, data link will be continued among normally operating stations without being disrupted at the power-down station.
Page 33 CHAPTER 1 OVERVIEW (5) Simple network parameter setting Network parameters required for network construction can be easily set up with the programming tool. Page 177, CHAPTER 6) (6) Network diagnostics Network status and the operating status of stations can be checked by the CC IE Control diagnostics of the programming tool, enabling quick troubleshooting at system startup and during operation.
Page 34 (7) Configuration of a redundant system (Compatibility with redundant CPUs) Page 138, Section 4.7) (a) Redundant system using CC-Link IE Controller Network modules By mounting a CC-Link IE Controller Network module to each of base units with redundant CPUs, a redundant system can be configured.
Page 35 CHAPTER 1 OVERVIEW (8) Project data common to normal stations For Universal model QCPUs, the station No. of a normal station (own station) can be set in the sequence program. If there are any normal stations that can share the same sequence program and network parameters (except for station No.), specifying their station numbers in the sequence program creates common project data for them, allowing easy data management.

Page 81 CHAPTER 4 FUNCTIONS (3) Interlock program When handling cyclic data of more than 32 bits, interlock the data in the link relay (LB). Handshake using link relay (LB) data can prevent data separation of the link register (LW). Program that sends data in W0 to W2 of station number 1 to W0 to W2 of station number 2 Handshake is performed by setting B0 to ON upon completion of storing send data.
Page 82: Cyclic Transmission Punctuality Assurance
4.1.6 Cyclic transmission punctuality assurance This function keeps the link scan time constant by making each station to send the specified number of transient transmissions within one link scan. ● Use this function to eliminate the fluctuation in link scan time, which is caused by transient transmissions. (Optimum cyclic transmissions are available.) Note that, if the network line status is unreliable, the cyclic transmission punctuality may not be ensured.
Page 83 CHAPTER 4 FUNCTIONS (2) When the punctuality assurance setting is enabled Each of stations performs the specified number of transient transmissions in one link scan to keep the link scan time constant, and the punctuality of cyclic transmission is ensured. (a) When the actual number of transient transmissions is less than the specified one Dummy data are sent to cover the shortfall.
Page 84: Constant Link Scan
4.1.7 Constant link scan This function is used to keep the link scan time to a preset time period. Set the constant link scan in "Supplementary Setting" of "Network Range Assignment" of the control station. Page 201, Section 6.3.6) ● This function is used to keep the link scan time constant even if the network line status is unreliable. Note that, if the actual link scan time is longer than the constant link scan time, the operation is performed based on the former.
Page 85: Group Cyclic Transmission
CHAPTER 4 FUNCTIONS 4.1.8 Group cyclic transmission *1*2 A Universal model QCPU can share cyclic data only with the stations that belong to the same shared group. It does not receive cyclic data of the stations in different shared groups. Stations with no shared group setting share cyclic data with all stations.
Page 86: Increase Of Send Points By Mounting Multiple Cc-Link Ie Controller Network Modules Of The Same Network No
4.1.9 Increase of send points by mounting multiple CC-Link IE Controller Network modules of the same network No. This function allows to increase send points by mounting multiple CC-Link IE Controller Network modules of the same *1*2 network No. with one CPU module. When one CC-Link IE Controller Network module is mounted, the send points per station are 16K points for both the link relay (LB) and the link register.
Page 87 CHAPTER 4 FUNCTIONS (1) Setting network parameters Set the same network No. to multiple CC-Link IE Controller Network modules in the network setting. The setting is explained using the following system configuration, where two CC-Link IE Controller Network modules are mounted. The setting example indicates this part of the configuration.
