  • Page 15 Wiring precautions • Place the Ethernet cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact. • Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt or dust is attached to the core, it can increase transmission loss, arising a problem in data link.

    FUNCTIONS This chapter describes the functions of CC-Link IE Field Network Basic. When the C Controller module is used, refer to the following. MELSEC iQ-R C Controller Module User's Manual (Application) Cyclic Transmission This function periodically performs data communication between the master station and slave stations using link devices.
  • Page 25 (The 'Data link status' (SM1540) does not turn on.) In addition, the transmission status of CC-Link IE Field Network Basic diagnostics becomes "Unfixed". • When slave stations are divided into groups, each of the groups performs the cyclic transmission. For the data flow of group number setting, refer to the following.
  • Page 26 ( Page 39 Link Scan Setting) For example, check the current link scan time (when all slave stations normally operate) using the CC-Link IE Field Network Basic diagnostics, and then specify a value, which is about five times as long as the link scan time, for timeout time. (When the current link scan time is 10ms, specify 50ms for the timeout time.)
  • Page 27 ■An abnormal response received from a slave station The master station immediately disconnects the slave station regardless of the timeout time and the number of times for disconnection detection set in the link scan settings. The following table lists the special relay and special register operations when a slave station is disconnected. Special relay/special register Operation 'Cyclic transmission status' (SM1536)

  • Page 29 Precautions ■Latched devices of the CPU module If data in latched devices of the CPU module is cleared to zero in a program when the CPU module is powered off and on or reset, the data may be output without being cleared to zero, depending on the timing of link scan and link refresh. Take the following actions so as not to output the data in the latched devices of the CPU module.

After receiving responses from all the slave stations, the master station performs link refresh and starts the next link scan. Master station Slave station 1 Slave station 2...
  • Page 32: Group Number Setting

    Group number setting This function divides slave stations into groups by setting a group number to each slave station and each of groups performs the cyclic transmission. By organizing groups separating slave stations with shorter response processing time from ones with longer response processing time, the differences of the reference response times of each slave station does not badly affect the cyclic transmission.
  • Page 33 Data flow of cyclic transmission The following describes the data flow of cyclic transmission of when the group number setting is used. ■Basic operation The master station sends requests, that vary from a group to group, to all salve stations. Although slave stations receive multiple request messages from the master station, each slave station handles a request message for a group where each slave stations belong to.
