microIOC

Inbetriebnahme-Tipps fuer neue Schrittmotor-Systeme

• neue MicroIOCs / PMACs am Testsystem vollstaendig (!!!) anschliessen und mit LocalControl GUI konfigurieren.
• FE:
  • MAC-Adressen LAN1, LAN2, x-port fuer DHCP-server (-> ACO INN)
  • PXE-Verzeichnis, Links fuer IP (LAN1), OS Image-link
  • NFSINIT-Verzeichnis /common/export/nfsinit/ anlegen, Links entsprechend setzen
  • entsprechende FESA-Software (einzelne Motoren oder Schlitze???) in /common/export/fesa/local// bereitstellen und konfigurieren, Instanz mit Geraetenomenklaturen in DB eintragen
  • Schrittmotor-Konfigurationsdateien in /common/fesadata/data//slits-conf/ bereit stellen, Geraetenomenklaturen eintragen

Checkliste für Inbetriebnahme und Konfiguration von neuen MicroIOCs

Troubleshooting

Network Connection

MicroIOC nicht im ACC Netzwerk erreichbar

• Verkabelung (fehlerhafte/falsche LAN-Kabel), ACC Switch ports
• CF Karte noch eingesetzt, Boot-Konfiguration
• Keine DHCP-Addresse: Reset ACC Network Switch
• Fehlerhafter DHCP-Eintrag, MicroIOC erscheint mit falschem Hostnamen, oder gar nicht. (-> ACO/IN)
• Fehlerhafter PXE-Eintrag (-> ACO/IN/FEC)
• DHCP im BIOS nicht aktiviert?
• Falsches Datum im BIOS
• Falsches Boot-Setting (Launch PXE OpROM: disabled -> enabled)
• Verlängerungskabel / Adapter funktioniert nicht (cross-over Adapter nicht nutzbar!)

MicroIOC bootet nicht mehr nach hardware powercycle

• BIOS-Einstellungen fehlerhaft (falsches Datum, falsches Boot-Medium eingestellt (sollte sein: PXE))
• Mainboard-Batterie leer, nicht angeschlossen

MicroIOC bootet nicht, Netzteil-Luefter läuft, keine Ausgabe der Boot-Mitteilungen

• Stromversorgungskabel an Grafikkarte

Keine Verbindung möglich

• Ping und Verbindung mit MicroIOC funktioniert nicht: ACO/IN pruefen lassen, ob MAC-Adressen richtig eingetragen sind
• Verbindungsversuch mit LocalControl GUI scheitert:
  • Netzwerkkabel ist abgezogen
  • System ist fehlerhaft konfiguriert, z.B. fehlende Parameter in Konfigurationsdatei (-> Fehlermeldung deutet fälschlicherweise auf serielle Verbindung hin, bis 2020)
  • Encoder type in properties.ini ist falsch eingestellt. Muss ggfs. in properties.ini direkt eingetragen werden da Verbindung mit LocalControl GUI nicht möglich ist wegen seriellem Verbindungsfehler. (bis 2020)

• • System ist fehlerhaft verkabelt (aussen). Darauf achten dass jeweilige Buchsen für Potentiometer oder SSI-Gerät verwendet werden.
  • PMAC/MicroIOC ist ausgeschaltet...
  • Serielle Stecker oder Stromversorgungskabel innen (!) im MicroIOC nicht richtig aufgesteckt
  • Konfiguration: wenn nicht alle Motoren via Kabel angeschlossen sind, sollten sie z.B. als PMAC konfiguriert sein (z.B. motor8.encoderType=3).

• Die fehlende PDC SSI version HW-REV.B+FW-2.2 deutet auf ein Problem mit der PDC hin
  • entweder PDC selbst (defekt / veraltete Version / inkompatibler ADC)
  • Verkabelung
  • serielle Schnittstelle innerhalb der MicroIOC
• Ursache für die fehlerhafte Kommunikation mit der seriellen Schnittstelle kann auch ein fehlender Treiber sein. Dieser kann nur über eine http-Verbindung geladen werden, nicht über eine https-Verbindung:

• Eine alternative Fehlerquelle ist das verwendete serielle Kabel. Es sollte das richtige sein. -> SD/LOBI/AOBI
• (vor 2020: Möglicherweise ist auch die properties.ini-Datei die Fehlerursache. Es sollten keine Syntaxfehler enthalten sein. Es sollte der jeweils aktuelle Stand verwendet werden, z.B. inklusive Angaben für 'named positions' etc!!!)

SSI encoder comm / Potentiometer comm error

• PDC off
• PDC not connected to MicroIOC (cables?)
• PDC broken

Potentiometer comm error / PMAC comm error

• 'old' PDCs may have an incompatible ADC version, serial connection errors become visible on console when mode is switched to SSI; motors can still be operated in PMAC mode (disadvantage: position unknown)
• inside microIOC:
  • serial connection cable might not sit properly on two-lined plug socket
  • sometimes only reconnecting the plugs of the cables on the PCI-104-board helps
  • PCI-104 serial card might be broken
  • MicroIOC -internal cables, especially in older systems, might have an 'invisible corrosion' issue ("crevice corrosion"?!). It might help to simply reconnect the cables at their plug sockets.
  • cabling between PCI-104 card and connector on backside might have a defect
• software configuration, /dev/ttyCTI0 appears as /dev/ttyCTI1 for an unknown reason

No connection to PMAC

• socket connection problems: MicroIOC of a more recent generation (2nd) have an additional network interface built-in, the network interfaces have to be configured differently compared to the first version

Axis Interlock / Amplifier Fault

• Interlock-Stecker (2-polig Lemo am PDC Eingang des Kanals) zum Überbrücken des Interlock-Ausgangs
• cable between MicroIOC and PMAC controller connected?

Amplifier Fault

• 2023: may lead to an interlock which makes motor unusable remotely via DeviceControl
• if the amplifier fault is the only error displayed per motor it could be that it can be removed by moving the motor locally via LocalControl
• if moving the motor via LocalControl is not the solution to remove the amplifier mode it may help to configure the motor for PMAC mode. -> encoder problem

• check whether built version of 'lcd' matches the OS image libraries
• check with ldd whether all the required libraries are available on the OS, e.g. the slits driver etc
• hardware issue? internal power connection?

Error message: "Failed to kill motor"

• update of internal pmac code with PMACUtils required

Motor/Slit Moves

Motors move in one direction only, no matter the software settings or the connected motor / PDC

• check cable between motor and PDC, wrong pins might be connected

Motors don't move, no errors

• hardware reset may help (turn MicroIOC completely off using the switch in the back)
• sometimes a PMAC controller reboot may help
• screws between motor and drive loose (symptoms: motors receive commands either via FEX or Local Control GUI, but the position does not change; no errors reported)

Motors move via LocalControl, but not via DeviceControl

• step motor system is probably fine
• communication error between DeviceControl and FESA software? Network, JAPC, ...
• FESA software down
• FESA software is throwing exceptions for a reason
• Motors are stuck at outer borders

Motors don't move via DeviceControl

• no Local Control GUI instance should be connected to the stepper motor system in local control mode. Either switch to remote mode or wait 5 min until this happens automatically.

Motors don't move via DeviceControl and are in an outer position

• Motors may be in outer end position (check Status). In this case it may happen that motors are not moveable anymore in remote mode. A workaround is to switch the system to local mode and move the motor manually out of its impractical position. (observed on FRS and S-FRS systems)
• the motor configuration should be checked, especially the outer limits, the offsets, the position tolerances; perhaps a misconfiguration leads to the observed effect

Motor Pair / Slit does not move - no error message

• one (or both) motors may be in an outer end position (check Status). In this case it may happen that motors are not moveable anymore in remote mode. A workaround is to switch the system to local mode and move the motors manually out of their impractical position. (observed S-FRS systems)
• technically it is possible that the motor pair is not able to be moved to the center position / width because inner/outer limits are/will be reached. Try other settings or move the motors separately. No error is issued in this case.

Motors both in inner/outer HW/SW end position at the same time

• sure sign that no motor hardware is connected, cable not connected, connection between motor and PMAC controller interrupted, possible symptom: motor LED off on MicroIOC
• check, whether serial cables are connected according to motor configuration

Motor moves in one direction only, no matter what

• pins might be wrongly connected in cable between motor and PDC (the self-manufactured ones)
• or, there could also be a connector issue on the motor connection side
• wrong software configuration settings (limits, direction, etc.)

Motors move in opposite direction

• software configuration: pulse polarity (negative/positive)
• hardware bug: motor connections pins might be switched the wrong way (not necessarily the cable, but the motor connector, e.g. at the SFRS stepper motor system "media board")

Motor does not move fast enough with heavy load under vacuum, slips through

• check velocity settings and acceleration time, should be slower (e.g. half of set values)

Attempting to move a motor pair via FESA Explorer / DeviceControl: "FESA_10016 Invalid value: '0.0500..0003" not in range '[0; 0.005499..97]'

• software settings misconfiguration??? Check settings in LocalControl GUI; inner and outer limit settings must be defined properly and should not be mixed up!
• check: inner/outer limits, high/low limit offsets might be switched, low limit should be negative, high limit positive, position tolerances
• invalid motor positions, inability to move the motor pair???
• check polarity of low limit offset, should be negative
• exceptions are thrown in real time action, they stop subscriptions via JAPC, not via RDA

LocalControl GUI: actual position cannot be displayed on motor drive tab (-> N/A)

• software configuration: SSI encoder type selected?
• cables (axis) between MicroIOC and PDC not properly connected?

LocalControl GUI: actual and set positions don't match

• software configuration:
  • limit configuration?
  • motor counts
  • potentiometer length
  • steps per mm
  • offsets
  • position tolerances
  • slower velocity and acceleration time to avoid slips during moves of heavy loads under vacuum
• hardware
  • pin connections?
  • cable?

Subscriptions don't receive updated values of property parameters, get operations impossible

• thrown exceptions/conditions in RT action may stop the subscription notification thread

Software Setup

Paths

Configuration

• PXE-Verzeichnis, Links für IP, OS Image

NFS links

• MicroIOCs with the CFA533 LC display also contain a different ethernet network card. The network interfaces are configured appropriately in slits_cfa533.sh .
• The script to launch the lc display software should use /usr/bin/lcd_cfa533

Hardware Changes

• Optional: integration of PCM white rabbit timing receivers (FTRN)
• PMAC reset cable has to be removed within MBOX

  • Anleitungen zum Einbau des WR Timing Receivers: microIOC_user_manual_19_FTRN_Einbau_6.21.pdf, S. 67-69

  • Entfernen des Reset-Kabels zum PMAC-Controller: microIOC-MBOX-FAIR_repair_Manual.pdf, S. 7 ff

  • Wichtig: MicroIOC -interne Flachbandkabel an PCI-104-Board fuer RS 485-Kommunikation mit PMAC-Controller via ADC/SSI nicht vertauschen!

Firmware Updates

• PMAC update using pmac-utils
• SSI update, requires spezialized programmer
• CPLD update (2020: V10), requires JTAG programmer

WR Timing

Prerequisites

• FESA configuration: "timingReceiverPresent" global configuration field has to be set to "true".
• FESA configuration: event mapping per device
• FESA configuration: device configuration: accelerator, timing/accelerator zone
• check availability:

Inject Timing Events manually

• Set SettingTriggered -Property via fex or pdex:

user@asl74x slits-conf $ pdex YR09DSBHA SettingTriggered position=0.033 -sp2
NOMEN  = YR09DSBHA (MotorSlit_DU.yr09ci01 | Motor)
TIMDOM = CRYRING_RING (210)
|
SettingTriggered
Please report - UNKNOWN FESA ERROR: cmwrda.Rda.read: USER_ERROR: Error caused by: Field 'enabled' is missing data.. src/MotorSlit/Server/SettingTriggeredSetAction.cpp:90
device="YR09DSBHA" property="SettingTriggered" selector="FAIR.SELECTOR.P=2" requestType="SET"

• First tests: possible with the script /inject_events.sh, the script will inject a fake event with the number 104. The FESA software needs to be configured appropriately for this event.
• First tests: The selected cycle is: sequence index: 0, process index: 1, chain index: 0, timing group: 211
• Alternative script: ./opt/fesa/nfs/global/scripts/inject-event-id.sh 211 532 2 2 2 2

Troubleshooting

• enable enhanced log output: saftbus-ctl --enable-logging
• parse log output for emitted signals: saftbus-ctl --enable-logging
• disable enhanced log output: saftbus-ctl --disable-logging
• decode timing events
• auslesen, ob die Condition-Property AcceptLate gesetzt ist: saftbus-ctl --get-property de.gsi.saftlib.Condition /de/gsi/saftlib/tr0/software/_1/_1957747793 AcceptLate b
