10 Systems10.3.9. Reflashing firmware and FlexPendant10.3.9. Reflashing firmware and FlexPendantOverview of reflashingAfter replacing hardware units, such as axis computer, buses, etc., or installing newerversions of RobotWare, the system will automatically attempt reflashing the unit in order tomaintain hardware/software compatibility.Reflashing is loading appropriate firmware (hardware specific software) onto a specific unitrunning this software during operation.If RobotWare is upgraded on the controller, then the FlexPendant will reflash, i.e. update tothe new version, when connected.Note that performing any such replacements/updates might require running firmwareversions not available! To avoid jeopardizing the function of the system, ABB recommendsusing the same versions as earlier, unless these are unavailable.The units currently using the reflash function are:• Contactor interface board• Drive units• FlexPendant• Profibus master• Axis computer• Panel boardReflashing processThe automatic reflashing process, described below, must not be disturbed by switching off thecontroller while running:Step Event Info1. When the system is restarted, thesystem checks the versions of thefirmware used. These are checkedagainst the hardware versions used.2. If the hardware and firmware versionsdo not match, the system restarts itselfautomatically while going to a specificUpdate Mode.3. Was an appropriate firmware versionfound?If YES, the reflash will proceed.If NO, the system will stop. Proceed asdetailed in section Reflashing firmwarefailed in the Trouble shooting manual -IRC5.4. After performing a successful reflash,the system restarts.During the Update Mode, an attempt ismade to download appropriate firmwareonto the hardware while a message isvery briefly displayed on theFlexPendant.In either case, a message is very brieflydisplayed on the FlexPendant andstored in the event log.The actual reflashing may take a fewseconds or up to a few minutes,depending on the hardware to bereflashed.3HAC 16590-1 Revision: BContinues on next page263
