Replacing Or Adding On The Module - Hitachi FL.NET User Manual

6.1.1 Replacing or adding on the module

What you should get in preparation
① Personal computer (with S10V FL.NET System installed in it)
② RS-232C cable (or 10BASE-T cable if the communication module used is an ET.NET
module)
③ New or add-on FL.NET module (LQE702)
④ Copies of the parameter values for the module to be replaced. (These copies serve as a
substitute for the original parameter values when the original become inaccessible due to,
for example, a failure of the FL.NET module.)
⑤ Optional ET.NET module. Where an ET.NET module is installed, you can select
Ethernet as the communication type. For more information, refer to Section 2.1, "Names
and Functions of Each Part," and Section 3.2, "Mounting the Module," in the USER'S
MANUAL OPTION ET.NET (LQE520) (manual number SVE-1-103).
Replacement procedure
① Write down, on a piece of paper, the current settings of the rotary switches that are, as
shown below, accessible at the front side of the FL.NET module to be replaced.
② Write down also the current settings of two switches, labeled LADDER (toggle switch)
and T/M (rotary switch), respectively, that are, as shown below, accessible at the front side
of the LPU module.

③ Connect the personal computer and the LPU module together with the RS-232C cable.
④ Start the S10V FL.NET SYSTEM and save the existing settings to a dedicated file, called
an FL.NET setup information file (see "5.5.8 Saving setups" for details). If the existing
settings are not accessible for some reason, skip this step and use item ④ you got in
preparation.
⑤ Set the LPU module's LADDER switch in STOP position and turn off the power supply of
the controller unit.
⑥ Remove the connecting cables from the FL.NET module to be replaced.
