⑬ Remove the RS-232C cable from both the personal computer and LPU module, which
were connected together in Step ③.
⑭ Connect the optical fiber cables to the new SD.LINK module, the cables that were
removed from it in Step ⑥.
⑮ Set the LPU module's LADDER and T/M switches in the same way as you wrote down in
Step ②.
⑯ Turn on the power supply of the controller unit and check that the new SD.LINK module is
running normally. To accomplish this check, ensure that the new SD.LINK module's PR-
/SR-RX and PR-/SR-TX LEDs are all lit, but its ERR LED is not.
Add-on procedure (for adding on a sub-module)
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
an SD.LINK module.
② Ensure that your application system has been shut down. Then, set the LPU module's
LADDER switch in STOP position and turn off the power supply of the controller unit.
③ Mount the add-on SD.LINK module in place according to the instructions given under "3.2
Mounting the Module."
④ According to the information provided under "2.1 Names and Functions of Each Part,"
set the add-on SD.LINK module's MODU No. switch in such a way that a new sub-
module no. setting will not duplicate with the current MODU No. switch setting of the
existing main SD.LINK module.
⑤ According to the instructions given under "4.2 Setting Switches," set the new SD.LINK
module's CPL No. U and L switches in such a way that a new number setting will not
duplicate with any of the current number settings of the existing SD.LINK modules
forming the full-duplex ring.
⑥ 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
SD.LINK module (sub-module) by using the S10V OD.RING/SD.LINK system.
⑦ Reset the LPU module by setting the RESET switch in ON position and then in OFF
position at its front.
⑧ Turn off the power supply of the controller unit and connect the optical fiber cables from
the ring to the add-on SD.LINK module.
⑨ Set the LPU module's LADDER and T/M switches in the same way as you wrote down in
Step ①.
