Profinet IO protocol for industrial Ethernet.

Profinet IO industrial protocol over Ethernet TCP/IP

Profinet Logo

Lexium MDrive Ethernet TCP/IP products supporting Profinet are available in two motor styles:

  •  Standard or high-torque rotary motor
  • ACME screw external shaft linear actuator

Both stepper motor styles are available in open loop, closed loop or with a multi-turn absolute encoder.


Rotary products

Lexium MDrive Ethernet rotary stepper motor products with Profinet IO are available in standard sizes: NEMA 17, NEMA 23 & NEMA 34.

Linear products

Lexium MDrive Ethernet external shaft stepper motor linear actuator products with Profinet IO are available in standard sizes: NEMA 17 & NEMA 23.

Profinet overview

Profinet IO is used for data exchange between I/O controllers (PLC, etc.) and I/O devices (field devices) such as the Lexium MDrive Profinet. Profinet IO uses the proven communication model and application view of Profibus DP and extends it by Ethernet as the communication medium. Among other benefits, this provides a greater bandwidth and allows more stations on the network. The Profinet IO specifications define a protocol and an application interface for exchanging I/O data, alarms and diagnostics and for transmitting data records and logbook information. To exchange I/O data and alarms, Profinet IO is based directly on the Ethernet protocol. Profinet IO classifies devices into three types:
  1. IO Controllers, such as PLC’s, map IO data from Profinet IO devices, such as the Lexium MDrive.
  2. IO Devices, in this case the Lexium MDrive Profinet.
  3. IO Supervisors, such as a PC is used for commissioning and system diagnostics.
Novanta IMS Ethernet products support Profinet as an IO device with remote I/O on-board these integrated motion products. Available as open or closed loop with an internal magnetic encoder. Closed loop models feature hMTechnology.
