(chapter 3, page 3-6)
Shield terminal (SHD) and one frame ground (FG) terminal are internally
connected. Be sure to ground the FG terminal.
(chapter 4, page 4-2)
Only one IR.LINK module can be installed.
For the S10mini series, install option modules from the leftmost slot so that the
I/O module may not exist between the CPU module and an option module and
any empty slot may not exist between the option modules.
For the S10V series, there is no constraint on the mounting position and empty
slot.
When installing the J.NET module (model: LQE040 or LQE540) or J.NET-INT
module (model: LQE045 or LQE545) and the IR.LINK module simultaneously,
install the IR.LINK module as the sub-setting. When installing only the
IR.LINK module, install it as the main setting.
(chapter 4, page 4-4)
Before installing the IR.LINK system, be sure to exit all the currently open
Windows® programs. Do not forget to exit anti-virus software and other
memory-resident programs. If you install the IR.LINK system without exiting
such programs, an error may occur during installation. If such an error occurs,
first uninstall the IR.LINK system as directed in "4.2.2 Uninstalling," exit all the
Windows® programs, and then install the IR.LINK system again.
