26 Presentation Industrial Ethernet network For Modicon M221, M221 Book, M241 and M251 logic controllers and Modicon TM4ES4 Ethernet switch module Web servers Preconfigured Web server Using a simple web browser available on PC, smartphone or tablet, this server authorizes the following ready-to-use functions: v With no prior programming - Display of the I/O states - Controller diagnostics, and of its expansion and communication modules - Communication port diagnostics - I/O Scanner function diagnostics - Maintenance and configuration functions (Ethernet/IP, firewall, etc.) v After configuration - Viewing data values - Viewing their evolution over time (oscilloscope function) Viewer Web server The SoMachine programming software is used to create customized pages for viewing and monitoring devices. These pages can also be accessed on any mobile device such as a tablet or smartphone with any operating system (iOS, Android, Windows). Description of Ethernet services Network Global Variable List (NGVL) The NGVL protocol allows a controller to share data with other controllers on a local Ethernet network (LAN) or subscribe to data published by other controllers which support the NGVL protocol and thus allowing, for example, synchronization between control platforms. I/O Scanner (Industrial Ethernet Manager) The Industrial Ethernet Manager service is used to manage the exchange of remote I/O states over the Ethernet network after a simple configuration operation, with no need for special programming. I/O Scanning is performed transparently by means of read/write requests in accordance with the Modbus TCP or EtherNet/IP protocol, so we talk about Scanner Manager on Modbus TCP or Scanner Manager on EtherNet/IP. Slave Modbus TCP This function can be used to create a dedicated I/O table in the controller, which can be accessed via the Modbus TCP protocol and by a controller with the Modbus TCP I/O Scanner function. Fast Device Replacement (FDR) This service uses standard address management technologies (BOOTP, DHCP) and the TFTP (Trivial File Transfer Protocol) file management service, in order to simplify maintenance of Ethernet products. The FDR service is used to replace a device with a new device; the device is detected, reconfigured and automatically rebooted by the system. Access to files via FTP (File Transfer Protocol) This service provides access to the controller files from, for example, a PC (FTP client) and is used to exchange files such as application programs, data, etc. This service can be accessed even if the controller has no application program in its memory.
