The ioPAC 8600 Series modular programmable controllers are 100% modular, giving you the freedom to choose the power, backplane, communication, and I/O modules you need for your application. In addition, the ioPAC 8600 enhances the hardware system architecture and key features of the ioPAC 8020 and ioPAC 8500 combined, and has an Ethernet bus on the backplane to support Ethernet switch modules.

The ioPAC 8600 supports the C/C++ and IEC 61131-3 programming languages and ready-to-run services, including Modbus TCP/RTU, SNMP, data logging, and email alarms to fulfill different customer requirements. With active tag and MX-AOPC UA Suite data integration software, the ioPAC 8600 Series provides a comprehensive solution for data acquisition and control applications in harsh environments.

All New High-Performance CPU30 Module

Moxa’s ioPAC 8600-CPU30 module is equipped with a new 1GHz high-performance Cortex™ A8 CPU, which shortens the cycle time significantly, and allows users to run more programs simultaneously. With the CPU30 module’s 4 GB eMMC, the ioPAC 8600 can support more communication protocols for a wider range of scenarios, including a RESTful API for railway IIoT applications and DNP3 outstations for oil and gas applications. The CPU30 also reserves up to 1.7GB of internal storage that gives users the freedom to develop more complex programs for specific ioPAC applications. As an added bonus, users can develop programs directly on the ioPAC.

Tag-Centric Design and Ready-to-Run Service

Moxa’s ioPAC 8600 programmable controllers use a tag-centric design with ready-to-run services. The tag-centric design helps streamline the connection between the ioPAC 8600 controller and remote I/Os, and allows you to easily manage I/O status by implementing get/set routines to read-from/write-to tag values, even if you are not particularly familiar with PLC FBDs and APIs. The ready-to-run service allows programmers to rapidly configure services (SNMP, Modbus RTU/TCP, email alarms, etc.) without writing a single line of code, reducing the development of complicated communication applications to a few mouse clicks. The ioPAC 8600’s tag-centric design and ready-to-run service greatly increase an engineer’s productivity.

2-Wire Ethernet Technology

Moxa’s 2-wire Ethernet technology offers system integrators an attractive option for upgrading a train’s IP network to a 10/100 Mbps Ethernet backbone with existing 2-wire cable. This innovative technology greatly reduces cable usage by providing 100 Mbps Ethernet transmission over only two wires, thereby reducing the train’s weight and improving energy efficiency. The 2-wire Ethernet switch module supports Ethernet bypass functionality, ensuring that the Ethernet backbone will continue to operate even if one ioPAC unit is without power. As an added bonus, by installing two 2-wire Ethernet modules in one ioPAC unit, the network can transmit at 200 Mbps and provide a redundant architecture.

Compact, Lightweight Integrated Solution

The compact ioPAC 8600 programmable controller is well-suited for smaller sized installation spaces, and its lightweight design reduces energy consumption and allows the product to withstand the wear and tear of railway applications. However, the ioPAC’s small size does not limit its capabilities. The ioPAC 8600 is equipped with universal dual power inputs that support all railway power voltages. With support for both 85M and 86M modules, the ioPAC 8600 programmable controller can implement the wide variety of IO scenarios required by train applications. The ioPAC 8600 also supports a variety of communication interfaces, including Ethernet, serial, CAN, and HART. System integrators can control or monitor subsystems with the ioPAC 8600, which saves space and provides powerful functions that both fit within the system integrator’s budget and overcome installation difficulties.
