Industrial Applications

1. Compact machine sequencing controller

Ideal for compact automated machines that need deterministic sequence control with a 1 ms task cycle and built-in industrial networking.

Problem Solved

Provides a small-form-factor PLC CPU for machines that need fast scan performance and integrated connectivity without a separate controller stack.

2. Small motion platform with point-to-point axes

Fits machines requiring up to 4 PTP axes, such as indexing, pick-and-place, or light servo positioning systems.

Problem Solved

Eliminates the need for a separate motion controller when only a few point-to-point axes are required.

3. Edge-connected manufacturing cell with data logging

Suitable for cells that must exchange production data with higher-level systems through OPC-UA, SQL-oriented database connectivity, or TCP/IP.

Problem Solved

Solves the integration gap between shop-floor control and IT-level data exchange in a single controller.
