Add-on procedure
① Write down, on a piece of paper, the current settings of two switches, labeled LADDER
(toggle switch) and T/M (rotary switch), respectively, that are accessible at the front side
of the LPU module, the one that is installed in the controller unit in which you are adding
on a FL.NET module.

LADDER switch in STOP position and turn off the power supply of the controller unit.
③ Mount the add-on FL.NET module in place according to the instructions given under "3.2
Mounting the Module."
④ Set the add-on FL.NET module's MAIN/SUB selector switches in such a way that a new
module (1) setting, which must be a sub-module (1) setting, will not duplicate with the
current rotary switch settings of the existing main FL.NET module.
⑤ Connect the personal computer and the LPU module together with the RS-232C cable.
Then, turn on the power supply of the controller unit and set parameters for the add-on
FL.NET module by using the S10V FL.NET System.
