Reference Source
• Parameter Number: The number of the parameter.
• Name: The name of the parameter.
• Description: Details on the function or settings of the parameter.
• Setting Range: The setting range for the parameter.
• Default: The default (each control method has its own default. Therefore the default
changes when the control method is changed).
Refer to page 5-64 for defaults by control method.
• Changes during Run: Indicates whether or not the parameter can be changed while the MxC is in
operation.
Yes: Parameter settings can be changed while the Run Command is present.
No: Settings cannot be changed while the Run Command is present.
• Control Methods: Indicates the control methods in which the parameter can be monitored or set.
Q: Items which can be monitored and set in either Quick Programming Mode
or Advanced Programming Mode.
A: Items which can be monitored and set only in Advanced Programming
Mode.
No: Items which cannot be monitored or set for the control method.
• MEMOBUS Register: The register number used for MEMOBUS communications.
• Page: Reference page for more detailed information on the parameter.
