سيناريو: Office, corridor and public area lighting with automatic timing plus manual override via KNX panels

الأجهزة: الشعار!8 تحكم + CMK2000 + KNX 3-gang push-button panel + KNX lighting actuator

وظائف:

1. الشعار! 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: تقريبا. 8~12 KNX objects

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

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

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

الأجهزة: الشعار!8 + CMK2000 + KNX panels, KNX dimming actuators, KNX damper actuators, partition position switches (الشعار! local DI)

وظائف:

1. Partition position signals are sent to LOGO!; الشعار! 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, الشعار! 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

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

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

سيناريو: Daylight harvesting dimming for offices and exhibition halls

الأجهزة: الشعار!8 + CMK2000 + KNX light sensor, KNX 0-10V dimming actuator

وظائف:

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. الشعار! sends dimming percentage to KNX dimmer; manual dimming via panel retains higher priority

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

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

سيناريو: Small server rooms, المختبرات, exhibition halls; interlock for fresh air fans, electric heating and dehumidification

الأجهزة: الشعار!8 + CMK2000 + KNX temperature/humidity/CO₂ sensors, KNX damper actuators, local contactor outputs on LOGO!

وظائف:

1. KNX sensors upload temperature, RH and CO₂ concentration to LOGO!
2. الشعار! 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: الشعار! has native analog processing, delay and alarm functions; CMK2000 bridges KNX sensors and LOGO! منطق.

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

سيناريو: Underground garage roller shutter doors, access control and safety light curtain interlock

الأجهزة: الشعار!8 + CMK2000 + KNX access control panel, local safety light curtain DI, door motor contactor

وظائف:

1. KNX access button sends opening authorization signal to LOGO!
2. الشعار! 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

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

قضية 6: Peak Load Limiting (إدارة الطاقة, proven overseas solution)

سيناريو: Shops, apartment heating circuits, charging pile group power limitation

الأجهزة: الشعار!8.3+ firmware + CMK2000 + KNX energy meter gateway, multiple heating / charging pile contactors

وظائف:

1. Real-time active power from KNX meter is uploaded to LOGO!
2. الشعار! implements priority sequencing for 8 الأحمال; 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.

قضية 7: Auxiliary Industrial Skid (HVAC control cabinets, مضخات المياه, dust removal units integrated into building KNX)

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

الأجهزة: الشعار!8 + CMK2000

وظائف:

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

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

المزايا: الشعار! 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, ثنائي الاتجاه (KNX→LOGO / LOGO→KNX), mapped to LOGO! دي / دو, markers M, variables V and timers
2. Workflow for commissioning:

الشعار!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(شارع)Y 2×2×0.8, only red/black pair is used
4. القيود: S7 protocol is not supported, only KNX TP1; communication with LOGO! runs over Ethernet, not backplane bus.

مرجع الاختيار

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

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