Configured Channel Information Data
• The MV returns the configured channel information data in response to an FE5
command.
• The ID number of the output format is 25.
• You can use the CB command to specify whether or not the MV will return data of
measurement channels set to skip and computation channels set to OFF.
• The figure below indicates the format.
