    2 SPECIFICATIONS 2.1 Usage The SV.LINK module (Model LQE021) is used in conjunction with the MELSEC A Series sequencer or motion controller from Mitsubishi Electric Corp. (hereinafter abbreviated to Mitsubishi) to exercise the high-speed I/O communication function on a peer-to-peer basis. The high-speed I/O communication function is exercised to rapidly exchange I/O data between the S10mini and MELSEC device over an IEEE802.3-compliant physical line by using the UDP/IP protocol.

  • Page 29 4 USER GUIDE NOTE Restrictions on multi-port transceiver installation positions When multi-port transceivers are installed on the most distant coaxial cable segment in a system in which the maximum length of coaxial cables is 2,500 m (five segments), data delay time increases due to the installation. To avoid this, restrictions are placed on the multi-port transceiver installation positions.
  • Page 30 4 USER GUIDE NOTE When connecting a repeater between segments by using multi-port transceivers, it is also necessary to set the multi-port transceivers at the positions decreasing the distance between the most distant stations by 100 m each time in passes one of the multi-port transceiver.

  • Page 53: Limitations

    4 USER GUIDE 4.12 Limitations The following limitations are imposed on the use of SV.LINK: (1) Simultaneous use of SV.LINK and ET.NET modules When mounting the SV.LINK module and ET.NET module on the same mount base, perform setup so that the main module and submodule are distinctively defined. If both of them are defined as main modules or submodules, they do not normally operate because the CPU cannot distinguish between ET.NET and SV.LINK.
  • Page 54 4 USER GUIDE (5) Communication start timing The communication parameters are read and checked when the communication starts. Be sure to set the communication parameters in the BD register before starting the communication (by writing a value other than 0 to the communication start flag in the SV.LINK internal memory). If the communication is started before completion of communication parameter setup, a parameter error or abnormal operation may result.
