If the communications cycle is set to a fractional value, a warning (Data setting warning: A.94) isgenerated.MECHATROLINK-I (VER: 10H)COM_MODIn the following cases, a warning is generated and the command is ignored. Commands are also ignored in phase 2 (withno alarm).• If COM_MOD is set out of range: Data setting warning (A.94)• If SUBCMD is set to 1 in 17-byte data transmission: Data setting warning (A.94)• If SUBCMD is set to 1 for Ver. 1.0 (VER: 10H): Data setting warning (A.94)• If Bit6, Bit5, Bit4, Bit3, or Bit0 is set to 1: Data setting warning (A.94)Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0SUBCMD 0 0 0 DTMOD SYNCMOD 0SUBCMD Sub-commandsetting0 Sub-command not used1 Sub-command usedDTMOD CommunicationMode 00 Single data transfer modeSYNCMOD TransmissionSynchronization0 Move to phase 21 Move to phase 3Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit00 0 0 0 DTMOD SYNCMOD EXMODDTMOD CommunicationMode 00 Single data transfer modeSYNCMOD TransmissionSynchronization0 Move to phase 2 (Asynchronous communications status)1 Move to phase 3 (Synchronous communications status)EXMODRequest toestablish expanded/standardconnection0 Standard connection1Expanded connectionEven if SYNCMOD = 1 (synchronous comm.), SYNCMOD will be set to 0 for asynchronousdata transmission.
