MELSEC-A
4.1.6
List of parameter setting ranges
The parameters specify various PLC functions, device ranges and user memory
assignments of the AnSHCPU.
As shown in Table 4.4, the parameters have default settings so the user does not
have to set all the parameter items. If any parameter item needs to be modified,
please refer to the table for the allowed setting range.
The operating manuals for each peripheral device give details on parameter
settings.
