Installation & Commissioning Guide

• Install the CPU in the designated slot (typically slot 0) of the main rack.
• Ensure the rack power supply can deliver the required 850mA at 5V DC.
• Insert the PCMCIA memory card (if needed) before applying power.
• Connect programming devices or HMIs to the two integrated Mini-DIN serial ports.
• Configure the ports in Unity Pro software for the desired protocol (Modbus/Uni-Telway).
• Plan I/O rack expansion within the 2-rack or 4-rack configuration limits.
• Monitor the status LEDs for RUN, I/O, ERR, and TER activity during operation.

Frequently Asked Questions (FAQ)

• What is the main purpose of the PCMCIA card?

The PCMCIA card significantly expands the program memory from 96KB to 224KB. It also provides an additional 256KB of battery-backed data storage for recipes, logs, or data that must survive a power cycle.

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

Yes, you typically use one Mini-DIN port (TER) for programming with Unity Pro and the other (AUX) for connecting an HMI, SCADA system, or other Modbus devices, allowing simultaneous communication.

• How many I/O points can I actually connect with this CPU?

You can connect up to 512 discrete (digital) I/O points and 24 analogue I/O points across all configured racks. The actual limit depends on the mix of discrete and analogue modules you install.

• Why is the instruction throughput slower when using the PCMCIA card?

Accessing program logic from the external PCMCIA card memory adds a small delay compared to the faster internal RAM. For most applications, this difference is negligible, but for extremely time-critical loops, optimize by using less card memory.

• What do the two red LEDs (I/O and ERR) indicate?

The I/O (red) LED flashes if there is a configuration mismatch or communication fault with an I/O module. The ERR (red) LED lights for a major CPU or system fault, requiring a review of the hardware or program.
