1. End-of-Life Replacement Solutions (System 2005 to X20 Migration)

Решение 1: Direct replacement within the same architecture (retaining System 2005 rack, spare part procurement)

No compatible upgraded model in the same series. The 3IF661.9 has been officially discontinued; only used/refurbished spare parts are available.

Решение 2: Full system upgrade to X20 (Recommended for new projects & retrofits)

Примечания по замене

1. System 2005 programs cannot be migrated directly to X20; hardware configuration, bus mapping and compilation must be reworked.
2. PROFIBUS GSD files are fully compatible, no modifications required for DP slave devices.
3. Backplane bus, power supply and mounting dimensions are completely incompatible; full replacement of X20 CPU + base unit is mandatory.

Complete Communication Parameter Configuration Tutorial for B&R 3IF661.9 (System2005 PROFIBUS DP Master)

Preconditions

1. Hardware Constraints

Compatible only with System2005 rack CPUs (3CPxxx/3RPxxx), installed in the IF communication slot to the right of CPU (IO slots forbidden); максимум 1 unit per CPU.

DP bus accessories: Standard 0G1000 DP connectors; set terminating resistor to ON for the first & last bus nodes, OFF for intermediate nodes.

2. Software Environment

Automation Studio V4.0 ~ V4.7 (Hardware library for System2005 is removed in versions above V4.7)

System2005 full hardware library must be loaded; native driver for 3IF661.9 included, no separate module GSD import needed.

3. File Preparation

GSD files for all DP slave devices (инверторы, remote IO, инструменты, и т. д.)

1. Hardware Rack Configuration (Physical View)
2. Create a new standard project and select the corresponding 3CP/3RP System2005 CPU.
3. Switch to the Physical View hardware view on the left, drag and drop the CPU onto the rack.
4. Drag and drop module `3IF661.9` into the IF expansion slot on the right of the CPU.

> Примечание: Slot position must match physical hardware; hardware mismatch error will be triggered during download otherwise.

4. Right-click 3IF661.9 → Configuration to open the DP master parameter panel.
5. Core DP Master Communication Parameter Settings (3IF661.9 Configuration)
6. General Bus Parameters (General Tab)

2. Advanced Bus Control Parameters (Advanced Tab)
3. Retry count: Retransmission times upon communication failure; default = 3, adjust to 5 for high-interference environments.
4. Gap factor: DP token gap; keep default value 10.
5. Diagnostic enable: Check to activate slave diagnostic functions for fault code reading via PLC program.
6. Sync/Freeze support: Check for motion control synchronization scenarios; uncheck for standard IO applications.
7. Key Operation Mode Note

The 3IF661.9 acts as a Class 1 DP Master, supporting cyclic IO data exchange only. Slave mode and direct cross-slave DX communication are not supported.

III. Import DP Slave GSD Files & Configure Slaves

1. Top menu bar of AS: 【Tools】→【3rd Party Device Manager】(Third-party Device Manager)
2. Click 【Import Fieldbus Devices】 to import all slave `.gsd` files.
3. Return to the configuration window of 3IF661.9 and switch to the 【Topology】 bus topology tab.
4. Locate imported DP slaves in the left hardware library, drag and drop onto the DP bus line.
5. Double-click each slave to assign a unique station address (1~126), not overlapping with master address.
6. Double-click the slave to access IO mapping page; select input/output byte length matching device datasheet.
7. IO Process Data Mapping (I/O Mapping – Core PLC Program Interface)
8. Switch to the 【I/O Mapping】 tab in the 3IF661.9 configuration window.
9. DP_In (data received from slaves to PLC) & DP_Out (control commands sent from PLC to slaves) channels are displayed on the left.
10. Bind global or program variables as shown below:

Inverter frequency setpoint: Bind `Program.DP_Out.Freq_Set` to Slave Output Byte 0~1

Motor current feedback: Bind `Program.DP_In.Motor_Current` to Slave Input Byte 2~3

4. Mapping Rules

Set Consistency to All universally to prevent fragmented data misalignment

Maximum IO length per single slave shall not exceed 244 байты (DP standard limitation)

1. Compilation, Скачать & Communication Diagnostics
2. Download Workflow
3. Click 【Apply】 to save module configuration after all parameters are set.
4. Build the whole project; download to System2005 CPU if no hardware errors occur.
5. Module LED Status Definition

PWR solid green: Backplane power supply normal

BUS flashing green: DP bus communication established normally

BUS solid red: Bus disconnection / duplicate address / mismatched baud rate

ERR solid red: Slave fault / mismatched IO mapping length

3. Open 【System Diagnostics Manager】 in online mode.
4. Filter for the 3IF661.9 module to view:

Bus packet transmit/receive counters

List of offline/fault slave station numbers

Watchdog timeout & CRC communication error counters

3. Rapid Fault Localization

All slaves offline: Проверьте скорость передачи данных, terminating resistors and A/B wiring

Single slave offline: Check hardware DIP station address, GSD IO PPO type and A/B wiring

1. Common Configuration Errors & Избежание ловушек
2. Incorrect slot insertion: Installing 3IF661.9 into IO slot triggers hardware error during download.
3. Duplicate station address: Master address = 1; slaves cannot use address 1; адрес 0 must not be assigned to any device.
4. Несоответствующая скорость передачи данных: Any slave with inconsistent baud rate will result in solid red BUS LED and total communication loss.
5. Missing/wrong GSD version: Slaves cannot be added or IO mapping table empty; reimport original manufacturer GSD file.
6. Overly short cycle time: Target Rotation Time < 2 ms causes frequent packet loss and bus alarms.
7. Chinese characters in project path: GSD import failure & compilation error; only English & numerals allowed in file paths.

VIII. Supplementary End-of-Life Migration Reference

The legacy System2005 rack-mounted 3IF661.9 cannot be used directly in X20 systems. Recommended upgrade replacement model: X20IF1061. Configuration logic is consistent, yet backplane and hardware library are fully incompatible, requiring full CPU & base unit replacement.
