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).

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.
