Configuration Method for Solidot Distributed I/O XBF4-EC04 Coupler on Keyence KV Series PLCs

The Keyence KV Series PLC features an innovative motor control Universal Library, supports the IEC 61131-3 international PLC programming standard, and includes an operation recording function that captures all variables/all soft elements/camera/event data during faults. Below describes the parameter configuration method for the Solidot Distributed I/O XBF4-EC04 Coupler on the Keyence KV platform.

I. Configuring Slot Models

Example:
XBF Interface 1 connects 2 I/O modules:
Model XBF2E-0808A (DIP switch station address: 0)
Model XBF2E-0016A (DIP switch station address: 4)
XBF Interface 2 connects 1 I/O module:
Model XBF2E-0808A (DIP switch station address: 1)

Note:
The XBF4-EC04 Coupler has 4 XBF interfaces with 64 slots total.

• Each XBF interface supports serial connection of up to 16 I/O modules (DIP switch addresses 0~F, must be unique).

• Single coupler supports expansion of up to 32 XBF series I/O modules.
  Slot Allocation:

• Slots 1-16: XBF Interface 1

• Slots 17-32: XBF Interface 2

• Slots 33-48: XBF Interface 3

• Slots 49-64: XBF Interface 4

III. Parameter Configuration

1. Digital Input Filter Parameters

Digital input filtering prevents program responses to unintended rapid signal changes caused by contact bounce or electrical noise.

• Configurable per module (not per channel).

• Default filter time: 3ms.
  Supported range: No filter, 0.1ms, 0.2ms, 0.5ms, 1ms, 2ms, 3ms (factory default), 4ms..18ms, 19ms, 20ms.
  Functionality:

• A 3ms filter blocks noise pulses shorter than 3ms.

• Signal transitions (0→1 or 1→0) must persist ≥3ms to be detected.
  Example: When configured to 1ms, a 250μs pulse is rejected as invalid.

2. Digital Output Clear/Hold Parameters

Configures output channel behavior during non-Operational (OP) states (e.g., PLC stop or coupler network disconnection).
Supported modes:

• Clear Outputs: Outputs reset to 0.

• Output Valid Value: Outputs maintain 1.

• Hold Last Value: Outputs retain pre-fault state.

Configuration Modes:

• Template Mode (default): Applies single setting to all channels.

• Single-Channel Mode: Per-channel override.
  Single-Channel Mode has higher priority than Template Mode.
  Default: Template Mode → Clear Outputs.

IV. Configuration Procedure Example

1. Initialization Communication Command

• nn: Slot number (0x00 to 0x3F, corresponds to expanded I/O modules).

• m: Parameter index of the module.

2. Configure DI Filter Parameter

Default: 3ms. Adjust as needed.

3. Configure DO Clear/Hold Parameter

Template Mode (default = 1):

• 1: Clear Outputs

• 2: Output All 1

• 3: Hold Last Value

Single-Channel Mode (default = 0):

• 0: Use Template Mode

• 1: Single-Channel Clear Output

• 2: Single-Channel Output 1

• 3: Single-Channel Hold Last Value

4. Bus Baud Rate Setting

Default: 6MHz. Adjust as needed.
