Frequently Asked Questions (FAQ)

• What is the purpose of the PCMCIA card slot?

The PCMCIA card slot expands the controller's memory significantly. It allows you to store larger programs (up to 128K words) and retain data during power outages, which is essential for complex applications.

• Can I connect both a programming terminal and an HMI to the serial ports?

Yes, the base has two dedicated serial links. Typically, the TER/AUX port is used for programming (Uni-Telway), and the Modbus RTU port can connect to an HMI, SCADA system, or other Modbus slave devices simultaneously.

• What types of modules can I add to the three expansion slots?

You can add a variety of TSX Micro I/O modules, including digital input/output, analogue input/output, communication modules (e.g., Ethernet), and counter modules to customize the system for your application.

• How does the "Immunity to microbreaks < 20 ms" feature help?

This means the controller will not reset or fault during very brief power dips or interruptions lasting less than 20 milliseconds. This is common in industrial environments and prevents nuisance stoppages.

• Is the on-board 0.5A, 5V DC output sufficient to power external sensors?

It is designed for low-power logic, such as keeping a real-time clock chip alive or powering a small buffer. For powering multiple sensors, you should use a separate, properly rated 24V DC power supply connected to your I/O modules.
