6 Spare Part Replacement Solutions

Opţiune 1: Direct replacement within the same platform (minimal modification, priority for maintenance retrofits)

Compatible CPU: 3CP38260-1

Note: Program requires no major changes; verify CF card program image and task cycle timing Pin-to-pin plug-and-play compatible

Risc: Also obsolete; supply availability is unstable

Opţiune 2: Cross-platform upgrade (long-term project migration, System2005 → X20)

Recommended new platform: X20 CPUs (X20CP1485 / X20CP1585)

⚠️ Major Modification Risks

1 Rack and all I/O modules must be fully replaced (System2005 I/O cannot connect directly to X20)

2 CEX bus eliminated; I/O communication migrated to POWERLINK; all wiring and backplanes require rework

3 Program migration and restructuring mandatory; old System2005 projects cannot be downloaded directly to X20 CPUs

4 Communication interfaces and real-time task timing need full re-commissioning

7 Selecţie & Operation Pitfall Guide

1 CompactFlash Card Restrictions

Only industrial-grade standard CF cards are supported CFast / CFexpress are incompatible Recommended capacity: 32 MB ~ 512 MB; high-capacity cards frequently cause recognition failures

2 Battery Maintenance

Risk of SRAM variable loss and RTC clock reset if equipment remains shutdown longer than 4 years Replace internal lithium battery during major overhauls

3 Critical Software Version Limit

Automation Studio V41 and newer cannot create or download projects for System2005 Keep AS V4095 available

4 aPCI Expansion Constraints

Maximum one IF7xx card per slot High-power communication cards increase total power consumption; verify cabinet power margin

5 Acceptance Checklist for Used Module Procurement

Verify CF card read/write and program boot functionality

Inspect battery voltage and check for electrolyte leakage

Test connectivity of Ethernet and serial ports

Run long-duration full-load testing to monitor ERROR LED status

8 Typical Industry Applications

Mașini de ambalare, plastic extrusion lines, utilaje textile, masini-unelte, tire production lines, legacy ACOPOS servo integrated equipment (primarily spare parts maintenance for existing installations)

3CP38060-1 Fault Troubleshooting Matrix: Fenomene, Cauze fundamentale & Acțiuni de remediere

LED Indicator Related Faults

1 READY LED OFF

Simptom: No READY light after power-up; controller fails to boot

Cauze fundamentale:

1 Insufficient backplane 24 Alimentare VDC / excessive voltage drop

2 Poor contact of CPU module backplane; DIN rail latch not fully locked

3 Damaged internal power circuit of the module

4 Rack short-circuit triggering overcurrent protection

Remedial Steps:

1 Measure rack supply voltage under no-load and loaded conditions; ensure voltage ≥225 V

2 Opriți, extract CPU, clean backplane gold fingers, reinstall and lock securely

3 Remove all aPCI expansion cards and CF card; perform minimum system power-on test

4 If READY remains off under minimum system configuration → hardware failure, repair or replacement required

2 READY Steady ON, RUN LED OFF

Simptom: Hardware ready, but user program fails to start

Cauze fundamentale:

1 Missing / damaged CF card / corrupted program image

2 CF card exceeds supported capacity limit or consumer-grade CF compatibility issue

3 Incorrect Boot project configuration in the application

4 SRAM data anomaly triggers self-test failure during startup

Remedial Steps:

1 Opriți, extract CF card, verify program files via card reader

2 Use industrial CF cards of 32~512 MB; consumer memory cards prohibited

3 Clear SRAM: Power off and rest for 15 minutes to fully deplete backup battery, then re-power

4 Download Boot & Application again using Automation Studio V4095

3 ERROR Red LED Steady ON / Intermitent

Simptom: System operational fault

4 SERVICE LED Illuminated

Simptom: Maintenance warning; does not trigger immediate shutdown

Cauze fundamentale:

1 Low voltage of built-in backup lithium battery (most frequent)

2 CF card read/write error or storage medium aging

Remedial Steps:

1 Schedule downtime to replace the internal 3 V lithium battery; battery leakage risks PCB corrosion

2 Back up programs and replace with new industrial CF card

> ⚠️ Equipment can continue short-term production under warning; replace components promptly to avoid permanent loss of retained variables after power failure

5 BAT LED Illuminated

Simptom: Backup battery warning

Cauza de bază: Aged internal lithium battery with voltage drop

Risc: RTC clock reset and complete loss of 512 KB SRAM retained data after power cycle

Rezoluţie: Power off and replace with equivalent 3 V lithium battery; minimize power-off duration during replacement

6 Abnormal CF LED Flashing

Continuous fast flashing: Frequent CF card access, indicative of aging media

No illumination: Mainboard fails to detect CF card

Communication Faults

IF2 Ethernet Communication Failure

Cauze:

1 Defective network cable or switch port; 100 Mbps controller, incompatible with forced Gigabit negotiation

2 IP address conflict or IP configuration lost in CF card

3 Damaged galvanic isolation circuit on Ethernet port

Depanare:

1 Direct PC-to-CPU Ethernet connection, disable PC firewall, scan via Automation Studio

2 Set switch port fixed to 100 Mbps Full Duplex (System2005 CPUs cannot auto-negotiate Gigabit)

3 If Ethernet offline: Use IF1 RS232 serial port for diagnostics and restore Ethernet parameters

Unstable IF1 RS232 Serial Communication

Critical Note: IF1 and USB share non-isolated ground!

Hazard: Potential serial chip burnout caused by ground potential difference when IF1 connects to third-party equipment

Soluţie: Install active RS232 isolator; prioritize baud rates 19200/38400; avoid permanent operation at 115200 baud

Communication Dropouts of aPCI IF7xx Expansion Cards

Inducing Factors:

1 Incomplete seating of expansion card

2 Exceeded overall power budget of backplane supply

3 Communication protocol not enabled within hardware configuration

Depanare: Temporarily remove expansion card and observe system recovery; verify hardware configuration in Automation Studio

Startup & Program-Related Typical Faults

1 Repeated power-on reboot

Inducement: Damaged CF card, excessive power supply ripple on backplane, short-circuit on aPCI card

Rezoluţie: Remove peripherals and perform minimum system test

2 All process parameters cleared after power loss

Inducement: Failed backup battery; variables not mapped to SRAM in program

Distinction: BAT LED ON → battery fault; BAT LED Normal → program variable configuration fault

3 Unable to establish online connection via Automation Studio

Hard Constraint: Only Automation Studio V4095 or older versions are supported

Versions higher than V4095 cannot recognize System2005 CPUs; do not attempt newer software

Fallback communication path: Use IF1 RS232 serial debugging if Ethernet fails

de mediu & Latent Hardware Faults

1 High cabinet temperature (>55°C)

Simptom: ERROR alarms and communication dropouts after several hours runtime; recovery after cooling

Soluţie: Improve cabinet ventilation; avoid heat-generating components mounted above the CPU; never sustain operation above rated 55°C

2 High vibration operating conditions

Simptom: Random communication flicker, occasional boot failures

Cauza: Loose CF card, poor contact of backplane gold fingers

Soluţie: Install CF card retaining clip, fasten all DIN rail mounting screws

⚠️ Strictly Forbidden Operations (Hard Limits)

1 Hot-swap CPU module or aPCI expansion cards! Always cut main power supply, otherwise backplane and CPU may suffer permanent damage

2 Use consumer-grade CF memory cards (camera cards); random program loss will occur frequently

3 Connect IF1 serial port and USB to external equipment with different ground potentials simultaneously; common-mode voltage can destroy interface circuits

4 Ignore battery warning for prolonged periods; battery leakage leads to irreversible PCB corrosion

5 Force switch port Gigabit negotiation to communicate with the CPU; persistent link interruptions will occur
