Therefore, change setting frequently makes EEP-ROM’s life short. Avoid to usage like this.5) Write a data within the range when you write it.7.3.3 Error Codes◇Basic procedure errorsError code Error name Explanation40H Bcc error ・A Bcc error occurred in the command data.41H Format error ・A command message was sent that does not fit the transmissionformat.42H No support error ・A command was sent that is not supported.43H Procedure error ・Delimiter with multiple frames was sent.・The response shall be multiple frames.◇Application errorError code Error name Explanation60H Parameter error ・The data code is not “D”.61H Data error・Word No. is specified without decimal.（0000F etc.）・The starting word No. is bigger than the ending word No.・Writing data has a code that is not hexadecimal.62H Registration error・Too many registrations have been entered (more than 17).・“MD” command was sent when some registration has been exist.・ “MG” command was sent when registration has not beenentered.◇Self-diagnostic errorError code Error name Explanation45H Operation error ・At “WD” command, writing data is exceeded the range of dataregister.7.3.4 CommandEco-POWER METER has 5 kinds of commands.Command name Code ExplanationRead data area RD Reads the contents of data area.Write data to data area WD Writes data to a data area.Resister or Reset data monitored MD Resisters the data to be monitored.Monitoring start MG Monitors a registered data.Read status RT Reads the specifications of Eco-POWER METER and error codeif an error occurs.
