Introduction to the Yokogawa ALE111-S00 Ethernet Communication Module The Yokogawa ALE111-S00 Ethernet Communication Module is designed to seamlessly integrate with safety control stations (SCS) for effective Modbus communication. This module enables the SCS to communicate with external systems via Ethernet, offering a reliable solution for data exchange between safety control units and other Modbus master devices. It's perfect for industrial environments where robust, secure, and efficient communication is vital. Key Features of the ALE111-S00 Module The ALE111-S00 module provides a range of features that optimize communication between safety control systems and external devices. It supports the Modbus slave communication function, enabling the SCS to send or receive data from a Modbus master system located elsewhere in the network. Some of its key features include: Transmission Speed: Supports 10 Mbps, making it suitable for fast and efficient data transmission. Physical Layer Interface: It follows the IEEE 802.3 10BASE-T standard for half-duplex communication. Connection Type: Uses an RJ-45 connector with point-to-point connections for straightforward integration into existing networks. How the ALE111-S00 Module Works The ALE111-S00 module allows Modbus communication between the SCS and other systems using an Ethernet connection. By leveraging the Modbus slave communication function of the SCS, the ALE111-S00 module enables the Modbus master device, a separate system from the SCS, to access and manipulate data in the SCS through the Ethernet connection. This communication setup is ideal for applications requiring remote monitoring, data logging, or integration with other industrial systems. Installation and Compatibility The ALE111-S00 module is designed for easy integration with the SSC60□, SSC50□, or SNB10D safety control units. These safety units are connected to the SCS via the ESB bus, ensuring seamless communication within the system. Additionally, the module can be mounted directly onto the aforementioned units, ensuring a compact, space-saving installation that doesn't compromise performance. Installation Highlights: Mounting: Can be mounted directly on SSC60□, SSC50□, or SNB10D units. Connector: The module uses a standard RJ-45 connector, making it easy to connect to existing Ethernet infrastructure. Transmission and Media Access The ALE111-S00 module operates using a 100 ohm twisted-pair cable, which is not shielded, ensuring cost-effective and reliable transmission. It supports a transmission distance of up to 100 meters, perfect for standard network setups between SCS and other systems or hubs. The module’s Media Access Control (MAC) employs CSMA/CD for efficient data transmission, making it highly reliable in busy network environments. Power Consumption and Weight The ALE111-S00 module is energy-efficient, consuming just 0.5 A of current during operation. It is also lightweight, weighing only 0.3 kg, making it easy to handle and i...
