Introduction

The ioPAC 6500 Series (also referred to as Intelligent Integrated Node or IIN) is an advanced Linux-based RTU featuring a built-in Layer-2 managed switch. Equipped with an Arm Cortex-A53 quad-core CPU, the ioPAC 6500 Series delivers robust performance.

6C Competencies

The ioPAC 6500 Series delivers the following competencies to your projects:

  • Control: Precision control of your equipment

  • Communication: Protocol support to connect to other devices and systems

  • Computing: Applications for computing and data processing

  • Connectivity: Versatile set of media interfaces

  • Cloud: Cloud connectivity and cloud edge computing

  • Cybersecurity: Security features to protect the devices and data

Fully Modular Design

The ioPAC 6500 Series features a unique Lego-like mechanical design that allows for flexible deployment while minimizing installation efforts. The series can be divided into the components: Backplane modules, power modules, communication modules, expansion modules, CPU modules, I/O modules, and terminal-block modules.

IEC 61131-3 Automation Programming

The ioPAC 6500 Series features IEC 61131-3 automation programming for flexibility in automation design and consistency in syntax and semantics, promoting interoperability between systems, thereby reducing development complexity in automation projects. Five languages are available: LD, FBD, SFC, IL, and ST, allowing automation professionals to choose the programming language that best suits their needs.
