6GK1503-0AA00 Übersicht
An Infrared Link Module (ILM) is a category of industrial wireless coupler that translates electrical PROFIBUS RS-485 signals into modulated infrared optical signals and back, providing a transparent cable replacement at the PROFIBUS protocol layer. ILMs sit within the broader hierarchy of industrial networking equipment: industrial communication > fieldbus > PROFIBUS > PROFIBUS coupler > wireless PROFIBUS link > infrared link module. Unlike Wi-Fi or Bluetooth bridges, ILMs use line-of-sight infrared, which avoids RF licensing requirements and is immune to electromagnetic interference, but requires an unobstructed optical path between paired units.
Key features of the 6GK1503-0AA00 include IP65 ingress protection for dust and water-jet resistance, support for all standard PROFIBUS baud rates up to 1.5 Mbit/s, and a rugged housing engineered for industrial shop-floor conditions. The 15 m maximum link distance supports typical cell-level applications such as AGV-to-wayside communication, turnstile controllers, and overhead crane data links. Compared with slip-ring or cable-reel alternatives, the ILM eliminates mechanical wear entirely.
Technically, the device implements an optically-isolated PROFIBUS interface on each side, regenerating signal timing and amplitude to maintain PROFIBUS timing budgets across the wireless segment. The IP65 enclosure uses M12-style industrial connectors for power and PROFIBUS, allowing field installation without additional cabinets. The infrared transceivers are arranged for bidirectional full-duplex-style operation across paired ILM heads.
Typical applications include PROFIBUS links on automated guided vehicles (AGVs), overhead crane bus communication, rotating machine monitoring, turnstile access control, and any installation where a fixed cable would be subject to flex fatigue. The module is typically deployed as a paired set - one ILM on each side of the wireless link.
When designing with this device, plan for clear optical line-of-sight between paired units and account for dust accumulation on the IR windows in dirty environments. Power budgeting should assume the 7.58 W typical dissipation for thermal management of the enclosure. Note that the 6GK1503-0AA00 has been phased out; consider migration to modern wireless PROFIBUS alternatives or IWLAN-based bridges for new installations.

Typische Anwendungen
6GK1503-0AA00 ist geeignet für 6 Anwendungs: Automated Guided Vehicle (AGV) PROFIBUS Link, Overhead Crane PROFIBUS Bridge, Turnstile and Access Control PROFIBUS Link, Rotating Machinery Monitoring Station, Assembly Line Transfer Station Communication, Mining and Bulk-Material Conveyor Section Coupling.
Automated Guided Vehicle (AGV) PROFIBUS Link
The 6GK1503-0AA00 enables wireless PROFIBUS communication between an AGV fleet and a wayside master as the AGV traverses the cell. Its 0.5 m to 15 m infrared range covers the typical dock-to-AGV handover distance, and the IP65 housing survives the dust and water spray common on AGV paths. PROFIBUS DP data rates up to 1.5 Mbit/s are sufficient for vehicle dispatch, payload status, and battery telemetry, while the 24 V / 7.58 W supply matches standard AGV auxiliary rails.
Empfohlen
Overhead Crane PROFIBUS Bridge
The 6GK1503-0AA00 replaces festoon cable systems or slip rings on overhead crane bridges by providing a wireless PROFIBUS link between the moving trolley and the fixed bus. Crane travels up to 15 m fall within the ILM range, and eliminating the cable removes mechanical wear from continuous flexing. The rugged IP65 housing tolerates shop-floor dust, while the 1.5 Mbit/s data rate supports hoist-position feedback, load-cell data, and anti-sway control loops over PROFIBUS DP.
Empfohlen
Turnstile and Access Control PROFIBUS Link
The 6GK1503-0AA00 provides wireless PROFIBUS connectivity to rotating turnstile banks where physical cabling would twist and fail. Its 0.5 m minimum range covers the close-proximity optical alignment required across the rotating bearing, and the 15 m maximum accommodates larger lobby installations. The 1.5 Mbit/s PROFIBUS rate is more than sufficient for ticket-reader, barrier, and biometric-controller traffic at typical turnstile cycle rates.
Empfohlen
Rotating Machinery Monitoring Station
The 6GK1503-0AA00 supports wireless PROFIBUS communication to rotating test stands, indexed assembly tables, and rotary indexing machines where slip rings are unreliable. Infrared transmission is immune to the electromagnetic noise generated by variable-frequency drives on the same machine, and the IP65 rating handles coolant splash in machining cells. Data rates up to 1.5 Mbit/s stream vibration, torque, and position data from PROFIBUS-capable sensors on the rotating side back to the cell controller.
Empfohlen
Assembly Line Transfer Station Communication
The 6GK1503-0AA00 provides wireless PROFIBUS handoff between fixed line segments and indexing transfer tables where a sliding contact would wear out. Its 15 m range accommodates larger transfer-line geometries, and the IP65 enclosure tolerates weld spatter, coolant, and oil mist typical in body-shop and machining lines. With PROFIBUS DP up to 1.5 Mbit/s, the ILM is transparent to PLC handshaking and station-status telemetry without protocol conversion.
Empfohlen
Mining and Bulk-Material Conveyor Section Coupling
The 6GK1503-0AA00 couples PROFIBUS segments across short gaps on conveyor sections that move during operation, such as telescoping or tripper-car conveyors. The infrared link avoids the cable-management problems of festoon systems in dusty bulk-handling environments, while IP65 sealing tolerates coal dust and water spray. The 0.5 m to 15 m range covers the typical conveyor-trolley travel distance, and the 1.5 Mbit/s PROFIBUS rate supports belt-scale, belt-slip, and pull-cord switch telemetry.

Wichtigste Unterscheidungsmerkmale
- Wireless infrared PROFIBUS link eliminates moving-cable wear (vs. 6GK1503-3CB00)
- IP65 housing for cabinet-less shop-floor mounting (vs. 6GK1503-3CB00)
- Bidirectional infrared avoids RF licensing (vs. 6GK1503-3CB00)
Designhinweise
The 6GK1503-0AA00 must be installed as a paired set, with one ILM at each end of the optical path. Plan the mechanical layout so that the two units maintain clear line-of-sight across the full range of machinery travel. The minimum 0.5 m distance prevents optical front-end saturation, while the 15 m maximum bounds the infrared power budget - check the datasheet's optical-window cleaning interval for dusty environments.
Estimated: at the typical 0.3 A draw from a 24 V supply, the 6GK1503-0AA00 dissipates approximately 7.2 W into the IP65 enclosure. In a sealed cabinet-less installation, verify that the mounting surface can tolerate this continuous dissipation, and provide a thermal path to the steel structure if ambient temperatures approach 40 C. Use a 24 V rail with at least 25% current headroom above 0.3 A so that supply droop during cold-start does not reset the ILM.
Do not substitute the 6GK1503-0AA00 with a wired OLM without reviewing the network architecture - OLMs use fiber and require physical cable routing, while the ILM is wireless. Migration paths to SCALANCE W IWLAN require PROFIBUS-over-WLAN gateways and a redesigned topology. Verify that the receiving end of the IR link has been paired and that the optical window is clean before commissioning - a partial obstruction will appear as intermittent PROFIBUS errors rather than a hard fault.
