CHAPTER9 PARAMETERS
This chapter explains the parameters that are set when a PLC system is configured.
(1) Parameter types
There are the following CPU module parameters.
• PLC parameter ( Section 9.1)
Set when the PLC is used independently.
• Redundant CPU parameter ( Section 9.2)
Set when a redundant system is configured using the Redundant CPU.
• Network parameter ( Section 9.3)
The network parameter is set to use the CC-Link IE controller network module,
MELSECNET/H module, Ethernet module, or CC-Link module in combination
with the PLC.
• Remote password ( Section 9.4)
Set when the remote password function of the Ethernet, serial communication
and modem interface modules is used.
(2) Parameter setting method
Set the PLC parameters, redundant parameters, network parameters and remote
password parameters by GX Developer.
Refer to the following manual for the setting operation on GX Developer.
GX Developer Version 8 Operating Manual
POINT
In GX Developer, since the functions are not available to the CPU module being
used, it is not necessary to set the setting items displayed in gray (cannot be
selected) that are not explained in this section.
Remark
• When an error occurs in the parameter setting, the corresponding
parameter number indicated in the tables of this chapter is stored in the
special register (SD16 to 26).
• Refer to Appendix 2 for details of the special register (SD16 to 26).
• Identify the parameter error location from the parameter number.
Refer to Appendix 3 for the list of parameter numbers.
• Refer to CHAPTER 12 for the parameter reflection procedure.
