Product Overview
The Siemens A5E00086045 SIMATIC PG Serial Port Adapter is an interface accessory for Siemens SIMATIC Field PG programming devices. It adapts the programming device’s serial port connection between 9-pin and 25-pin D-sub connector formats, allowing compatible serial equipment to be connected to the appropriate interface.
In industrial automation maintenance, programming devices are often used to communicate with PLCs, configure control equipment, and diagnose existing installations. Older Siemens SIMATIC systems may use serial interfaces that differ from the connectors found on a particular programming device. This adapter addresses that physical interface difference, helping technicians connect compatible serial equipment without replacing the programming device itself.
For example, a maintenance engineer working with legacy automation equipment may need to connect a Field PG to a serial interface using a different D-sub connector format. The A5E00086045 provides the required connector adaptation for supported configurations. Successful communication still depends on the electrical interface, pin assignment, communication protocol, and software used by the connected equipment.
The adapter is a passive connection accessory rather than a PLC communication processor or an independent protocol converter. It does not provide Ethernet, USB, or fieldbus conversion. Before selecting it, technicians should verify the programming device model and the connector arrangement required by the intended serial connection.

Product Features
- D-sub connector adaptation: Provides conversion between compatible 9-pin and 25-pin serial connector formats.
- SIMATIC PG compatibility: Intended for use with supported Siemens programming-device configurations.
- Legacy equipment connectivity: Helps accommodate serial connections used by earlier automation equipment.
- Direct connection accessory: Provides connector adaptation without acting as a separate communication controller.
- Maintenance support: Useful when programming devices are used for commissioning, troubleshooting, and servicing.
- Model-specific selection: Requires confirmation of the Field PG interface and the connector arrangement required by the application.
Working Principle
The A5E00086045 adapts the physical connector arrangement of a compatible SIMATIC PG serial interface. Its function is to establish the appropriate connection between the programming device and the corresponding serial connector format.
A typical connection follows this arrangement:
SIMATIC Field PG Serial Port → A5E00086045 Adapter → Compatible Serial Equipment
The adapter allows the specified D-sub connector formats to be matched. It does not independently process PLC commands, translate communication protocols, or generate a new interface standard. The connected devices must still use compatible electrical signaling and communication settings.
For instance, when servicing a legacy controller, the programming device may require a different connector format from the one presented by the equipment. The adapter addresses that connector mismatch, while the programming software and serial communication configuration determine whether the devices can exchange data successfully.
Connector compatibility alone does not guarantee communication. Pin assignments, signal type, cable wiring, and the requirements of the connected equipment must be checked before use. Where a connection requires a special cable or a particular serial interface mode, the adapter should be used only within the specified arrangement.
Role in the SIMATIC Programming Setup
The A5E00086045 forms part of the physical connection between a Siemens programming device and compatible serial equipment. It supports the connection stage, while the programming device, communication software, and target equipment handle the actual data exchange.

Installation and Maintenance
- Verify the adapter reference: Confirm A5E00086045 and check that it matches the intended SIMATIC PG connection.
- Identify the programming device: Check the Field PG model and its serial-port connector arrangement before connecting the adapter.
- Check the target connector: Determine whether the connected equipment requires the compatible 9-pin or 25-pin D-sub format.
- Confirm interface compatibility: Verify that both devices use compatible serial signaling and that the adapter is appropriate for the intended connection.
- Inspect the connectors: Check the pins, connector shells, and securing hardware for bending, contamination, or mechanical damage.
- Verify pin assignment: Confirm that the intended connection uses the correct pin mapping and does not require a different cable arrangement.
- Power down where required: Follow the equipment’s connection procedure, particularly when the serial interface or target device requires disconnection before attachment.
- Fit the adapter securely: Align the connectors correctly and avoid forcing the adapter into place.
- Secure the connection: Tighten the connector fasteners where provided to prevent movement during maintenance work.
- Check the communication settings: Configure the programming software and target equipment for the required serial protocol and communication parameters.
- Test communication: Confirm that the programming device can establish the intended connection before carrying out programming or diagnostic operations.
- Store and document the accessory: Record the adapter reference and keep it protected from bent pins, impact, and contamination when not in use.

Technical FAQs
What is the main purpose of the Siemens A5E00086045?
It is a SIMATIC PG serial port adapter used to adapt compatible D-sub 9-pin and 25-pin connector formats on supported Field PG configurations.
Does the A5E00086045 convert serial communication into USB or Ethernet?
No. Its primary function is connector adaptation. It does not independently convert serial communication into USB or Ethernet or translate one industrial communication protocol into another.
Will this adapter work with every Siemens SIMATIC programming device?
Compatibility should be checked against the programming device’s model and serial-port configuration. The adapter is identified for supported SIMATIC Field PG arrangements, so connector similarity alone is not sufficient to establish compatibility.
What should be checked if the connected equipment does not communicate?
Check the connector format, pin assignment, cable wiring, serial interface type, and communication parameters. If the physical connection is correct, verify that the programming software and target device support the selected communication method.
