1. Overview and Communication Parameters

This document details the technical specifications and configuration parameters for the SICK T-Easic FTS IO-Link device, a flow and temperature sensor with automation functions. It supports IO-Link communication at COM3 speed (230.4 kbit/s) with a minimum cycle time of 5 ms. Access permissions for parameters include read-only (ro), write-only (wo), and read/write (rw).

2. Process Data Structure

Process data input is 6 bytes structured as follows:

• Bytes 0-1: Temperature as a 16-bit signed integer with 0.1°C resolution.
• Bytes 2-4: Flowrate as a 24-bit unsigned integer, representing velocity (0.01 m/s), volume (0.1 l/min), or relative flow (0.1%) depending on measurement mode.
• Byte 5: Status and control bits including boolean flags Q1 and Q2, device state (2-bit unsigned), reserved bits, and a warning active flag.

3. Physical Layer and Device Constraints

The device must operate within the master port’s maximum output current limits to prevent damage or communication failure. It supports SIO mode.

4. IO-Link Specific Parameters and Service Data

• Device Access Locks (Index 12): Controls data storage and local UI locks.
• Identification Strings (Indices 16-23): Read-only vendor, product, serial number, hardware and firmware version strings.
• Application Specific Tag (Index 24): 32-byte read/write custom tag.
• Device Status (Index 36): 8-bit status code indicating device condition (0=OK, 1=Maintenance required, etc.).
• Process Data Input (Index 40): 6-byte read-only process data as described above.

5. Device-Specific Parameters

• Teach Status (Index 59): Indicates teaching mode status with multiple states including idle, success, busy, and error conditions.
• Operation Timer (Index 190): 32-bit unsigned integer tracking operation time in seconds.
• Delay Modes and Times for Outputs Q1 and Q2 (Indices 212-215): Configurable delay types (Ton, Toff, pulse, or deactivated) and delay times (0–60000 ms).
• Q1 Mode (Index 260): Selects hysteresis or window modes for flow or temperature signals, including application-specific modes.
• Q1 Switchpoints (Indices 267-270): Configurable thresholds for flow relative (%), velocity (m/s), volume (l/min), and temperature (°C) with defined ranges and resolutions.

6. Parameter Specifications and Configuration

• Q2 Mode (0x122): Defines Q2 output behavior with options such as flow hysteresis/window, temperature hysteresis/window, logical input combinations, application-specific modes, or inactive.
• Q2 Switchpoints: Two configurable thresholds each for flow relative, velocity, volume, and temperature for alarms or control.
• Units Configuration: Parameters to set units for volume (L/min, L/h, m³/h, US gallons, ft³/min), velocity (m/s, ft/s), pipe diameter (mm, inch), and temperature (°C, °F).
• Display Mode (0x1A8): Configures display orientation and order of flow and temperature readings.
• Display Lock (0x1B1): Password-protected lock to prevent unauthorized HMI changes.
• Measurement Mode (0x1B8): Selects relative velocity, absolute velocity, absolute volume, or teach relative modes.
• Pipe Diameter (0x1B9): Adjustable from 1 to 1000 mm.
• Medium (0x1BA): Selects medium type (water, oil variants, etc.).

7. Simulation and Filtering

• Simulation (0x1BB): Enables flow (0–100%) and temperature (-25°C to 150°C) simulation modes for testing and diagnostics, including failure simulation.
• Filter (Process Data) (0x1BE): Configurable smoothing filter time from off to 10 seconds.
• Linear Flow Factor (0x1C0): Calibration factor adjustable between 50% and 150% for flow compensation.

8. Monitoring and Diagnostics

• Signal Quality (0x1E0): Read-only signal quality percentage (0–100%).
• PowerUp Counter (0x1E5): Counts device power cycles.
• Supply Voltage (0x1E6): Measured in millivolts.
• Sensor Temperature (0x1E7): Measured in 0.1°C units.
• Max/Min Medium Temperature (0x1E8/0x1E9): Recorded maximum and minimum medium temperatures.
• Reset Min/Max (0x1EE): Write-only command to reset min/max temperature values.
• Error Delay (0x1F4): Configurable error reporting delay (0–30 seconds).
• Error Level (0x1F5): Defines error reporting level: failure only or failure plus warning.
• Active Notifications (0x1F6): Bitfield indicating system states such as failure, warning, short circuit, supply voltage issues, simulation active, output driver errors, and internal warnings.

9. Standard Commands

• 75: Teach maximum value
• 76: Teach minimum value
• 128: Device reset
• 130: Restore factory settings

10. Temperature and Error Status Indicators

• Temperature status bits indicate process and sensor temperature limits exceeded (bits 28-31).
• Internal error indicator (bit 27) signals device internal errors.
• Hardware Identification Key: 16-byte read-only unique device identifier.

11. Recommendations and Limitations

• Operate device within specified current limits to avoid damage or communication failure.
• Interpret process data units and scaling correctly according to measurement mode.
• Some service data (e.g., Device Specific Tag, Simulation, Special Action Scratchpad) are not saved via Data-Storage.
• Monitor device status codes and active notifications for maintenance and operational health.
• Use display lock to secure settings against unauthorized changes.
• Utilize simulation modes for testing without actual process flow.
• Apply appropriate error delay and level settings to balance responsiveness and noise tolerance.
