The ioPAC 8600 modular RTU controllers are 100% modular, giving users the freedom to choose CPU, power, backplane, communication, and I/O modules. In addition, the ioPAC 8600 enhances the hardware system architecture and key features of the ioPAC 8020 and ioPAC 8500 combined. It not only preserves the dual CPU architecture to support all ioPAC 8600 I/O modules, but also adds 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, data logging, and email alarms to fulfill different customers’ requirements. With Moxa’s Active OPC Server and DA-Center data integration software, the ioPAC 8600 series provides a comprehensive solution for data acquisition and control applications in harsh environments.

2-Wire Ethernet Technology

2-wire Ethernet solutionMoxa’s 2-wire Ethernet technology offers system integrators an attractive option for upgrading the train’s IP network to a 10/100 Mbps* Ethernet backbone with existing 2-wire cable. This innovative 2-wire Ethernet technology supports Ethernet bypass functionality, ensuring that the Ethernet backbone will continue to operate even if one ioPAC is without power. As an added plus, with two 2-wire Ethernet modules in one ioPAC, the network can reach 200 Mbps and provide a redundant architecture.
*Network performance is related to cable quality when using 2-wire technology

Read-to-Run Service
ready-to-run platform
Moxa’s ioPAC 8600 programmable controllers allow programmers to rapidly configure services (SNMP, Modbus RTU/TCP Master/Slave, E-mail/SMS alarm service, etc.) without writing any programs. The ioPAC can reduce the configuration of massively distributed deployments to a few simple mouse clicks, greatly increasing engineers’ productivity.
Automatic Carriage Sequencing (ACS)
Efficient Automatic Carriage Sequencing
Moxa’s Automatic Carriage Sequencing technology quickly and automatically resets the train car sequence, without disrupting network transmissions within the train. This technology greatly reduces the operation effort required for trains that frequently rearrange consists. Onboard passenger information systems can also adjust immediately when changes are made.
Compact Integrated Solution
All-in-one Hardware Design
The compact ioPAC 8600 is equipped with universal dual-power inputs that support all railway power voltages, and a new channel-to-channel, high voltage DI/DO module is available for use in trains that use different power systems. The ioPAC 8600 supports a variety of communication interfaces, including Ethernet, serial, CAN*, and MVB*. System integrators can control or monitor sub-systems with the ioPAC 8600, which saves space and has powerful functions to reduce both the system integrators’ budget and installation difficulties.
