以太网 IO 模块

现场总线系统确保控制器与传感器/执行器级别之间的可靠数据传输。考虑未来的工业 4.0 场景时，灵活的自动化解决方案和实时数据传输变得比以往任何时候都更加重要。倍加福以太网 IO 模块完全符合此任务，可以快速轻松地将现场设备连接到更高级别的总线系统。这些模块支持常见的以太网协议：PROFINET、EtherNet/IP 和 EtherCAT。可以使用旋转开关直接在模块上设置所需类型。它们的多协议功能支持与所有通用控制面板直接进行以太网通信，而且只需一台设备。

以太网 IO 模块提供全面的诊断功能，提高了过程中的透明度。LED 提供每个通道的状态信息，始终允许进行通道特定诊断。集成 Web 服务器支持远程访问网络参数，如 IP 地址、子网掩码和网关。

这些模块配备了“分散式智能”功能，能够处理规模较小的应用，而不依赖于远程控制面板。模块自主评估参数，只有在必要时，才会将信息传输到 PLC。

这缓解了更高级别系统的压力，并缩短了反应时间，从而支持工业 4.0 场景的需求。

该模块的电源连接器带有 L 码 M12 插头连接，允许最高 16 A 的更高额定电流。因此，该模块能够满足更高的峰值负载，并且需要更少的缆线。

凭借完全封装的外壳，这些模块非常耐用，即使在恶劣条件下也能适用。坚固的设计允许多种安装选择。这简化了在现有工厂中的安装和集成。凭借这一系列创新功能，以太网 IO 模块提高了工厂效率。

In its portfolio of fieldbus modules, Pepperl+Fuchs offers Ethernet IO modules with integrated IO-Link master that allow seamless communication from IO-Link-enabled sensors/actuators to the control system. Up to eight IO-Link devices can be directly connected—four channels are available for sensor technology and four for actuators. The IO-Link master makes seamless parameterization, diagnostics, and predictive maintenance possible down to the sensor/actuator level.
Whereas the ICE1 series multi-protocol modules are ideally suited for PLC-based applications, the ICE2 and ICE3 series IO-Link masters with integrated OPC UA interface enable cloud-based Industry 4.0 solutions.

Aside from the range of fieldbus modules with integrated IO-Link master, Pepperl+Fuchs also offers Ethernet IO modules for up to 16 digital sensors and actuators. These modules support the most common Ethernet protocols—PROFINET, EtherNet/IP, and EtherCAT—in a single device. With “decentralized intelligence” as an optional function, digital modules can even solve small applications independently without first having to forward information to the control center. This relieves pressure on the higher-level system, increases response time, and supports the requirements of Industry 4.0.

Critical applications such as chemical or pharmaceutical plants require for system redundancy to prevent unplanned downtimes and the associated costs. For this reason, the communication mechanism of the new IO-Link masters supports the S2 redundancy functionality which allows an additional programmable logic controller (PLC) to take over process control automatically in the event of a control-related failure of the primary PLC. Compared to conventional I/O modules, the ICE1 masters with S2 redundancy come with a particularly resistant, diecast zinc housing and an extended temperature range that open up a wide range of applications the chemical and pharmaceutical sectors.

I/O hubs with IO-Link interface enable efficient incorporation of binary sensors/actuators into an intelligent IO-Link system. This is how only one junction line can transfer up to 16 digital IOs to an IO-Link master. The space-saving solutions reduce wiring effort and errors since both signal transmission and power supply take place along the same line. A rugged, molded metal housing and an extended temperature range from -25 °C to +70 °C make I/O hubs suited for use in harsh industrial environments.
