ifm AL13 series and Solidot IOL7A: an 8-port IO-Link-master comparison
Compare ifm AL1302/AL1333 and Solidot IOL7A PROFINET/EtherCAT IO-Link masters by ports, Class A, power, cycle, IP and IoT functions.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
Solidot IOL7A-PN01B-8A or IOL7A-EC01B-8A is a technical candidate for an 8-port IO-Link master. Do not assume identical multiprotocol, separate IoT-port, MQTT/JSON or Class-B capabilities to certain ifm AL models.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | ifm AL13xx / AL14xx IO-Link masters | Solidot / ProControl candidate |
|---|---|---|
| PLC network | PROFINET, EtherNet/IP, EtherCAT or other networks according to AL model. | IOL7A-PN is a separate PROFINET order code; IOL7A-EC is a separate EtherCAT code. |
| IO-Link ports | Port count, Class A/B and Pin-2 function vary by exact model. | The official record states 8×Class A, IO-Link V1.1.3, COM1/2/3, 0.5 A on Pin 4 and 2 A on Pin 2. |
| IoT layer | Some ifm AL13/14 models provide a separate IoT port and MQTT/JSON interface. | The current IOL7A official record does not publish a separate IoT port or MQTT/JSON, so it must not be assumed. |
| Device management | IODD, parameter storage, web tool and replacement workflow vary by model. | IODD loading, parameter storage, configuration backup and device replacement require commissioning tests. |
| Field conditions | IP, M12 coding, US/UA and port power budget depend on exact model. | The IOL7A official record states IP67, 18–30 VDC and -25…+70 °C; calculate total power budget from connected loads. |
Suitable scenario
When is it worth evaluating?
- New 8-port IO-Link field stations
- Projects with a fixed PROFINET or EtherCAT network
- Standard sensor/actuator applications without a separate IoT-path requirement
Migration gate
Before making a decision
- Export the exact ifm AL code and used ports.
- Record Class A/B, COM speed, SIO and current for each port.
- Add IODD and parameter-storage requirements to the test plan.
- Verify the PLC device file and process-data length.
- Test sensor replacement, short circuit and network interruption.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Is the same Solidot model used for PROFINET and EtherCAT?
No. IOL7A-PN01B-8A is for PROFINET and IOL7A-EC01B-8A is for EtherCAT.
