Description
The MVI46 EtherNet/IP (DF1 for Ethernet) Client/Server Communication Module is an SLC backplane compatible module that allows SLC processors to interface easily with EtherNet/IP protocol (Explicit Messaging) compatible devices and hosts. Devices commonly supporting the protocol include Rockwell Automation PLCs, and host HMI systems. Features and Benefits: The MVI46-DFNT module is a single slot solution that provides a powerful connection between Rockwell Automation's SLC processor and EtherNet/IP (DF1 for Ethernet) network applications. The module can send read or write commands to remote devices on the EtherNet/IP network. The MVI46-DFNT also has 20 servers that allow the module to receive commands from remote devices. The MVI46-DFNT Pass-Through server allows the user to edit and transfer the SLC ladder logic using an Ethernet connection. Up to 100 commands can be configured by the user. General Specifications: • Single Slot – 1746 backplane compatible (Local or extended I/O rack only. Remote rack not supported) • The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module using M0/M1 files • Ladder Logic is used for data transfer between module and processor. Sample ladder file included • Configuration data obtained from configuration text file downloaded to module. Sample configuration file included Functional Specifications: • Rockwell Automation 5/02/03/04 processors with DH-485 or DH+ network connections to co-exist with EtherNet/IP network • SLC 5/05 in-chassis EtherNet/IP bridge to optimize data throughput while communicating with MMI or SCADA and other control platforms without losing valuable process control bandwidth • Support of up to 4000 SLC registers user data files • User-definable module memory usage • 10/100 MB Ethernet compatible interface • Functions as a server or a client • Configurable parameters for the client include: -A minimum response delay of 0 to 65535 mSec -A response timeout of 1 to 65535 mSec -A retry count of 0 to 20 • Status data available in ladder logic Support for SLC processor programming over Ethernet using a TCP/IP service and a serial port on the module connected to channel 0 of the processor. The module's third port emulates Channel 0 of the processor to pass through messages from the port to the processor. Server Specifications: • Supports EtherNet/IP explicit, connected, and unconnected class messaging • Twenty independent server connections permit remote clients to interact with all data contained in the module • Data can be derived from other clients on the network, through the client on the module, or from the SLC processor Client Specifications: • Actively issues connected, explicit messages to other nodes on the network • Supports 100 user-defined commands from a single client • Allows command control from ladder logic • Pass-through services • Permits remote programming of the SLC processor on the Ethernet network via a pass-through • TCP/IP service and a serial communication port (pass-through port) on the module • A PC with RSLogix 500, RSLinx, and a TCP/IP service on the network can remotely program the SLC • The third port on the module can emulate the Channel 0 port on the SLC. This allows a DF1 master device attached to the emulated (Channel 0) port to monitor and control data in the SLC.
