CC-Link Master Station Parameter Configuration (for AJ65SBTB1-32D, Remote I/O Station, يحتل 1 station)
Master module: QJ61BT11N (Q-series); برامج البرمجة: GX Works2; AJ65SBTB1-32D = Remote I/O Station, يحتل 1 station, 32-point RX input, no RY output and no RW registers.
Master station fixed station number: Station 0. Slave AJ65SBTB1-32D station number set via DIP switch: 1~64. Station 1 is used in this example.
- Hardware DIP Switch (Set AJ65SBTB1-32D first!)
- Station number DIP switch: Binary DIP switch for station address (على سبيل المثال. Station 1 = 00000001)
- Baud rate DIP switch: Must match master station baud rate
000 → 156kbps
001 → 625kbps
010 → 2.5Mbps (most commonly used on site)
011 → 5Mbps
100 →10Mbps
Fit 110Ω terminating resistors at both ends of the bus

Station Information (شديد الأهمية!)
Click [Station Information], add Station No.1:
| غرض | جلسة | |
| Station No. | 1 | DIP station number of AJ65SBTB1-32D |
| Station Type | Remote I/O Station | ⚠️ NOT Remote Device Station! |
| Occupied Stations | 1 | AJ65SBTB1-32D fixed as 1 station |
| RX(Remote Input) | 32 نقاط | X0~X1F (corresponds to 32DI) |
| RY(Remote Output) | 0 نقاط | This module has inputs only, no outputs |
| RWw/RWr | 0 words | Remote I/O stations do not use registers |
Remote I/O station soft element mapping rule:
Station1: RX0~RX1F correspond to the 32 DI channels of AJ65SBTB1-32D
PLC internal soft elements for master station: RX mapped to PLC X addresses (auto-refreshed by GX Works)
- Soft Element Refresh Mapping (QJ61BT11N)
CC-Link automatic refresh:
RX: Remote input → PLC internal X
RY: PLC output → Remote module output
RWw: PLC writes to remote registers
RWr: Remote registers read into PLC
AJ65SBTB1-32D (Station 1)
RX0~RX1F (32قليل) = 32 DC input channels of the module
مثال: Sensor ON → RXn=ON; read RX bit directly in program.
- FX5U + FX5-CCL-MS (FX5U CC-Link Master, GX Works2/3)
FX5U with FX5-CCL-MS master card can connect AJ65SBTB1-32D
- Project → Parameters → CC-Link Parameters, Master type: Master station, Ver.1 mode
- Add station entry for Station 1: Remote I/O Station, يحتل 1 station, RX=32, RY=0
- Soft element refresh: RX mapped to FX5U X or M (customizable refresh address)
FX5U built-in Ethernet CC-Link IE Field Basic cannot directly connect old AJ65SBTB1-32D. This classic CC-Link uses RS485 bus and requires FX5-CCL-MS module.
- تحميل & خطوات التكليف
- Complete all parameter settings, انقر [يفحص], confirm no errors;
- Write [حدود + Program] to PLC; PLC reset;
- Power up remote modules with DC24V first, then power up PLC master station;
- Observe indicators:
M/S: Master steady ON; يجري: Slave steady ON;
ERR off = Communication normal; ERR flashing = bus fault;
- Online monitor RX soft elements; trigger sensors and verify corresponding RX bits turn ON/OFF.
- Common Mistakes
- ❌ Wrong station type: selected as Remote Device Station → communication failure; must use Remote I/O Station
- ❌ Baud rate mismatch between master and slave
- ❌ Missing terminating resistors, random disconnection over long cables
- ❌ Duplicate station numbers, frequent in multi-slave networks
- ❌ Ver.2 mode enabled; old AJ65SBTB1-32D is Ver.1 compatible, use Remote Net Ver.1 Mode by priority
- Sample Program (شارع / Ladder compatible)
Directly monitor RX0~RX1F, no special communication instruction required, CC-Link auto cyclic refresh.
مثال: LD RX0 reads channel 0 input of AJ65SBTB1-32D.

| C940 | Data link stop | Bus break / interference / missing terminator | Check DA DB wiring, shield earthing, terminating resistors |
- Q-series CC-Link Special Relay SW (Monitor in GX Works)
Identify offline station quickly via SW registers
- SW0080~SW0083: Link error bits, bit maps to station number. ON = fault at that station
SW0080 bit0 = Station1 fault; bit1 = Station2 fault, and so on
- SW006B: Detailed error type
0: طبيعي
1: Transmission line fault
2: Parameter error
3: CRC error (التداخل الكهرومغناطيسي)
4: Timeout error (slave no response)
5: Abort error
6: Setting error
- On-site Troubleshooting Sequence (AJ65SBTB1-32D)
- Check slave PW lamp: OFF → inspect DC24V supply
- Check slave L.RUN / L.ERR lamp
- Open GX Works → CC-Link Diagnosis, read fault code + SW0080 to locate faulty station
- يؤكد: station number, معدل الباود, station type (Remote I/O Station)
- Check DA/DB polarity, 110Ω terminators at both bus ends
- Single-point earthing for shield; avoid both-end earthing to prevent ground loop
- Separate CC-Link cable away from power cables to reduce interference
- Common Pitfall Summary
- Remote I/O Station mistakenly selected as Remote Device Station → BBC2 station type error, ERR flashing
- Master Ver.2 mode enabled, old AJ65SBTB1-32D incompatible → B983 invalid module type
- Terminating resistor fitted only on one end → random flashing, intermittent disconnection
- DA DB wires reversed, entire bus down, master ERR steady ON
- Modify DIP switches while powered on, slave L.ERR flashes periodically; power cycle to recover
