3. Physical and environmental parameters

Physical structure: Dual European standard PCB, including 1 diagnostic display dedicated PCB

Space requirement: 8 SU (European Standard Installation Unit)

Buffer battery: model CR 2477N (HIMA part number 44 00000 18), lifespan: 1000 days at 25 ℃, 200 days at 60 ℃, recommended for replacement up to 6 years

Key configuration methods

1. Bus station address setting (via switches S1-1-7)

Basic settings: S1-1~5 are used to set addresses 1-31

Extension settings: Combined with S1-6-7, it can be extended to addresses 1-99 (requires OS version ≥ BS41q/51q V7.0-8)

Switch logic: White switch OFF=set, ON=not set

Network restriction: Up to 64 communication partners

2. Transmission rate setting (via switch S1-8)

Switch status transmission rate

S1-8 ON 9600 bps

S1-8 OFF 57600 bps

Functional characteristics and operation

1. Diagnosis and troubleshooting

Diagnostic display: 4-digit alphanumeric matrix display, supporting selection to view various types of information

Fault indication: Two LEDs respectively indicate faults in the central module (CPU) and testable I/O module (IO)

Operation buttons: 2 toggle switches for querying detailed fault information; The ACK key is used to reset the fault indication, and when the fault stops, it is equivalent to a system restart

Fault safety: Built in fault safety watchdog ensures safe shutdown triggered in case of malfunction

2. Installation and plugging operations

Disassembly steps: Completely loosen the fixing screws → Press down on the front label to remove the ejection lever → Quickly pull out the module upwards (to avoid triggering the wrong signal)

Installation steps: Place the module on the terminal block → quickly press inward to the bottom (to avoid triggering error signals)

3. Special features (corresponding to OS version)

Self learning function: OS ≥ BS41q/51q V7.0-8 (05.31) support

ELOP II TCP: Supports connection to PADT and Ethernet network communication partners (such as safeEthernet, Modbus TCP), requires cooperation with the F 8627X communication module

Communication path: Central module → Backplane bus → F 8627X → Ethernet network

Maintenance and Precautions

Battery maintenance: When the “BATI” prompt is displayed, it needs to be replaced within 3 months; It is recommended to replace it within a maximum of 6 years when there is no prompt

Configuration check: Before starting, it is necessary to confirm that the bus station address and transmission rate settings of S1 switch are correct

Upgrade note: When upgrading from F 8650 to F 8650X, the fan design needs to be changed synchronously
