No direct hardware replacement model; CMK2000 (6BK1700-0BA20-0AA0) is the only option for KNX connection of LOGO! 8 シリーズ

If KNX is not required and only Ethernet communication is needed, select LOGO! models with built-in Ethernet (PN variants marked 6ED1052)

よくあるトラブルシューティング

KNX bus communication failure: Check KNX polarity, bus power supply and bus wiring; wire cross-section 0.6~1.0 mm²

Web page inaccessible: Confirm the PC is in the same network segment as LOGO! and wait for module startup completion after power-on

Communication objects not refreshed: Verify LOGO! firmware version and mapping direction (input/output) of group addresses

Application Cases for 6BK1700-0BA20-0AA0 (CMK2000)

Core principle: ロゴ!8/8.2 executes local logic, タイミング, threshold comparison and interlocking; CMK2000 works as a bidirectional gateway to connect KNX bus panels, actuators and sensors. マックス. 50 KNX communication objects. ETS5/ETS6 is used for KNX side configuration, and LOGO!Soft Comfort for LOGO! programming and object mapping.

場合 1: KNX Astronomical Timer + Central Lighting Control (シーメンス official sample ID:109745699)

シナリオ: オフィス, corridor and public area lighting with automatic timing plus manual override via KNX panels

ハードウェア: ロゴ!8 controller + CMK2000 + KNX 3-gang push-button panel + KNX lighting actuator

機能:

1. ロゴ! built-in astronomical timer (sunrise/sunset), weekly/yearly timer automatically sends ON/OFF commands to KNX actuators
2. Button signals from KNX panels are uploaded to LOGO! for forced switching and scene selection; panel LEDs receive status feedback from LOGO!
3. KNX bus provides time synchronization for LOGO!; time and status can be viewed on TDE text display and LOGO! built-in web page

Object allocation: 約. 8~12 KNX objects

利点: No KNX timers required. Leverage LOGO!’s flexible annual calendar and holiday disable logic for automatic lighting shutdown during holidays.

場合 2: Zoned Control for Multi-Room Movable Partition (Official sample ID:109748585)

シナリオ: Conference room, multi-function hall, automatic lighting and air conditioning zoning when movable partitions are opened or closed

ハードウェア: ロゴ!8 + CMK2000 + KNX panels, KNX dimming actuators, KNX damper actuators, partition position switches (ロゴ! local DI)

機能:

1. Partition position signals are sent to LOGO!; ロゴ! judges whether the space is a single large hall or multiple independent rooms
2. Zone status is synchronized to KNX bus; when a scene is triggered on the KNX panel, ロゴ! enables lighting and air conditioning according to zoning logic
3. Cross-zone interlock: When partitions are separated, the panel of zone A cannot control loads in zone B

利点: KNX only handles panels and actuators, while complex zoning interlocking logic runs in LOGO!, greatly simplifying ETS projects.

場合 3: Illuminance Threshold Dimming Control (Official sample ID:109748587)

シナリオ: Daylight harvesting dimming for offices and exhibition halls

ハードウェア: ロゴ!8 + CMK2000 + KNX light sensor, KNX 0-10V dimming actuator

機能:

1. KNX illuminance value (0~255) is uploaded to LOGO! analog variable
2. Threshold comparison and hysteresis filtering are implemented in LOGO! to avoid frequent flickering
3. ロゴ! sends dimming percentage to KNX dimmer; manual dimming via panel retains higher priority

特徴: ロゴ! performs filtering, limit protection and delay; KNX only transfers measured values and control values.

場合 4: HVAC Temperature / 湿度 + CO₂ Ventilation Interlock (Fresh air for buildings or small server rooms)

シナリオ: Small server rooms, 研究室, exhibition halls; interlock for fresh air fans, electric heating and dehumidification

ハードウェア: ロゴ!8 + CMK2000 + KNX temperature/humidity/CO₂ sensors, KNX damper actuators, local contactor outputs on LOGO!

機能:

1. KNX sensors upload temperature, RH and CO₂ concentration to LOGO!
2. ロゴ! executes PID or threshold logic: increase fresh air when CO₂ exceeds limit, start heating at low temperature, activate dehumidification at high humidity
3. Operation status, fault signals and setpoints are sent back to KNX for display on central panels or touch screens

Fitment: ロゴ! has native analog processing, delay and alarm functions; CMK2000 bridges KNX sensors and LOGO! 論理.

場合 5: Gate / Garage Door Safety Interlock (Official sample ID:109748589)

シナリオ: Underground garage roller shutter doors, access control and safety light curtain interlock

ハードウェア: ロゴ!8 + CMK2000 + KNX access control panel, local safety light curtain DI, door motor contactor

機能:

1. KNX access button sends opening authorization signal to LOGO!
2. ロゴ! performs safety interlock: door opening permitted only when the light curtain is clear and limit switches are normal; auto-close after timeout
3. Door status, fault and lock status are fed back to KNX panel LED indicators

価値: Safety interlock logic runs locally in LOGO!; protection remains valid even if the KNX bus is offline.

場合 6: Peak Load Limiting (エネルギー管理, proven overseas solution)

シナリオ: Shops, apartment heating circuits, charging pile group power limitation

ハードウェア: ロゴ!8.3+ ファームウェア + CMK2000 + KNX energy meter gateway, multiple heating / charging pile contactors

機能:

1. Real-time active power from KNX meter is uploaded to LOGO!
2. ロゴ! implements priority sequencing for 8 負荷; high-priority loads are retained and low-priority loads are shed when total power exceeds threshold
3. Shedding status and current power are sent back to KNX supervision system

Critical requirement: Firmware ≥ FS4, otherwise KNX object binding fails.

場合 7: Auxiliary Industrial Skid (HVAC control cabinets, ウォーターポンプ, dust removal units integrated into building KNX)

シナリオ: Factory auxiliary equipment, chiller units, exhaust fan cabinets; upload equipment status to the building KNX automation system

ハードウェア: ロゴ!8 + CMK2000

機能:

ロゴ! collects pump run status, 故障, hand-auto mode, temperature and pressure via local DI/AI

状態, alarms and setpoints are uploaded to KNX through CMK2000; start/stop and setpoints can be issued from KNX side

利点: ロゴ! provides reliable local control for industrial equipment; expensive KNX IO modules are not required for interconnection between industrial control and building bus.

General Implementation Notes (Applicable to all cases)

1. Maximum communication objects: 50, 双方向 (KNX→LOGO / LOGO→KNX), mapped to LOGO! ディ/ドゥ, markers M, variables V and timers
2. Workflow for commissioning:

ロゴ!Soft Comfort: Write logic, add CMK2000, define KNX objects and direction

CMK2000 web page: IP configuration, KNX parameters, diagnostics and online monitoring

ETS5/ETS6: KNX device database, group address binding and download to KNX bus devices

3. Bus accessories: Standard KNX bus power supply is mandatory; KNX cable J-Y(ST)Y 2×2×0.8, only red/black pair is used
4. 制限事項: S7 protocol is not supported, only KNX TP1; communication with LOGO! runs over Ethernet, not backplane bus.

選定基準

For simple direct load control by KNX panels: CMK2000 is not needed

Where complex timing, astronomical clock, 連動する, filtering, local IO acquisition and offline protection are required: CMK2000 + ロゴ! is a cost-effective solution.
