⑥ Remove the connecting cables from the CPU LINK module to be replaced.
⑦ Replace the existing CPU LINK module with the new one and set the new CPU LINK
module's rotary switches in the same way as you wrote down in Step ①.
⑧ Turn on the power supply of the controller unit. Then, check that the PCs edition
information is identical between the two CPU LINK modules, old and new, by using the
S10 CPU LINK System.
⑨ Turn off the power supply of the controller unit.
⑩ Remove the RS-232C cable from both the personal computer and CPU module, which were
connected together in Step ③.
⑪ Connect to the new CPU LINK module the connecting cables that you removed in Step ⑥.
⑫ Set the CPU module's LADDER, MODE, and PROTECT switches in the same way as you
wrote down in Step ②.
⑬ Turn on the power supply of the controller unit and check that the new CPU LINK module is

Add-on procedure
① Write down, on a piece of paper, the current settings of three switches, labeled LADDER
(toggle switch), MODE (toggle switch), and PROTECT (toggle switch), respectively, that are
accessible at the front side of the CPU module, the one that is installed in the controller unit
in which you are adding on a CPU LINK module.
② Ensure that your application system has been shut down. Then, set the CPU module's
LADDER switch in STOP position and turn off the power supply of the controller unit.
③ Mount the add-on CPU LINK module in place according to the instructions given under
"1.2 Mounting the Module."
④ Set the add-on CPU LINK module's rotary switches in such a way that a new setting will not
duplicate with any of the current rotary switch settings of the main CPU LINK module.
⑤ Connect the personal computer and the CPU module together with the RS-232C cable.
Then, turn on the power supply of the controller unit and set parameters for the add-on CPU
LINK module by using the S10 CPU LINK System.
⑥ Reset the CPU module by pressing the RESET switch at its front.
⑦ Turn off the power supply of the controller unit and connect the connecting cables to the
add-on CPU LINK module.
⑧ Set the CPU module's LADDER, MODE, and PROTECT switches in the same way as you
wrote down in Step ①.
⑨ Remove the RS-232C cable from both the personal computer and CPU module, which were
connected together in Step ⑤.
⑩ Turn on the power supply of the controller unit and check that the add-on CPU LINK module
