More Information

Overview Manuals DP Roles Segment Scale LED Diagnosis PCI Integration

Features:

  • A floating RS-485 interface carries PROFIBUS traffic at up to 12 Mbit/s.
  • The short PCI card supports PCI/PCI-X hosts with Plug-and-Play installation.
  • DP master operation scales to 124 slaves, with DP slave operation available as an alternative.
The processor separates PROFIBUS communication from host-side data handling through event-driven change detection.

A direct segment supports 32 devices, while repeater-linked segments extend the documented network to 124 nodes.

Green and yellow LED patterns distinguish master, slave, startup, diagnostic and exception conditions.

The Siemens 6GK1561-3AA01 CP 5613 A2 Communications Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6GK1561-3AA01 CP 5613 A2 Communications Processor Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Master and slave selection

  • Master Path: 6GK1561-3AA01 is optimized for DP master operation through DP Base.
  • Slave Alternative: The same processor can be configured as a DP slave.
  • Consistency: Master operation retains full data consistency across the documented slave set.
  • Host Relief: Event mechanisms signal data changes without continuous host polling.

PROFIBUS node organization

  • Base Segment: One segment can contain as many as 32 linked devices.
  • Extension: Repeaters join multiple segments into the larger network.
  • Network Limit: The documented repeater-connected total is 124 nodes.
  • Interface: All field traffic passes through the floating RS-485 connector.

Interpreting the two status colors

  • Green Steady: Token rotation identifies normal DP master operation.
  • Yellow Steady: Polling by the higher-level master identifies normal DP slave operation.
  • Alternating Flash: A diagnostic tool is addressing the installed processor.
  • Synchronized Flash: The module has entered a firmware exception state.

Host-card relationship

  • Slot Standard: The board follows PCI V2.2 and PCI-X host compatibility.
  • Voltage Keying: The card accepts 3.3 V or 5 V PCI signaling.
  • Bus Width: The interface supports 32-bit operation at 33 or 66 MHz.
  • Discovery: Plug-and-Play support identifies the hardware during installation.
Description
Siemens 6GK1561-3AA01 is the SIMATIC NET CP 5613 A2 communications processor for connecting a PC to PROFIBUS. Its single floating RS-485 interface carries PROFIBUS traffic at rates from 9.6 kbit/s to 12 Mbit/s.

The short PCI design of 6GK1561-3AA01 uses a PCI/PCI-X host slot and supports 3.3 V or 5 V signaling, 32-bit operation and 33/66 MHz bus clocks. Plug-and-Play hardware detection works with event mechanisms on the card that identify data changes before passing them to the host.

A direct PROFIBUS segment built around 6GK1561-3AA01 can link as many as 32 devices. Repeater-connected segments raise the documented network total to 124 nodes, while the processor can run as an optimized DP master for up to 124 DP slaves or be configured as a DP slave.

The green and yellow indicators on 6GK1561-3AA01 separate master token rotation, slave polling, diagnostic addressing, startup and firmware exception states. The PROFIBUS connection is a screw-locked 9-pin D-sub female interface.

Before installing 6GK1561-3AA01, what must be checked in the host PC?
Before fitting 6GK1561-3AA01, confirm a compatible PCI or PCI-X slot with 3.3 V or 5 V signaling, 32-bit operation and a 33/66 MHz bus clock.
If the green LED on 6GK1561-3AA01 stays dark in DP master mode, which faults should be checked?
A dark green LED on 6GK1561-3AA01 can indicate incorrect bus parameters, a defective PROFIBUS path or a processor that is not operating.
What does alternating green and yellow flashing on 6GK1561-3AA01 tell the technician?
Alternating green and yellow flashes mean that a diagnostic tool is addressing 6GK1561-3AA01 to verify its installation.
Can 6GK1561-3AA01 be assigned as a PROFIBUS slave instead of a master?
DP slave operation is supported by 6GK1561-3AA01 as an alternative to its optimized DP master role.
How should the node count be planned around 6GK1561-3AA01?
With 6GK1561-3AA01, one direct segment supports up to 32 devices; repeater-linked segments can extend the documented total to 124 nodes.
