The MVI46 Modbus Plus Dual Port Network Interface Module allow Rockwell Automation SLC processors to connect directly on Modbus Plus networks as a peer. The module acts as an input/output module between the Modbus Plus network and the processor. Compatible devices can be found in most industries and include devices such as drives, relays and power monitor hardware.
Rockwell Automation 5/02/03/04 processors with DH-485 or DH+ network connections to co-exist with EtherNet/IP network
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
User-definable module memory usage
A minimum response delay of 0 to 65535 mSec
Functions as a server or a client
A response timeout of 1 to 65535 mSec
Support of up to 4000 SLC registers user data files
Configurable parameters for the client include:
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
10/100 MB Ethernet compatible interface
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
Allows command control from ladder logic
Actively issues connected, explicit messages to other nodes on the network
Supports 100 user-defined commands from a single client
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.
Permits remote programming of the SLC processor on the Ethernet network via a pass-through
Compatible devices include not only Modicon PLCs (most of which support the Modbus Plus protocol) but also a wide assortment of end devices licensed through the ModConnect Program. The MVI46-MBP module acts as an input/output module between the Modbus Plus network and the Rockwell Automation backplane. The data transfer from the SLC processor is asynchronous from the actions on the Modbus Plus network. A 4000-word register space in the module exchanges data between the processor and the Modbus Plus network.
Crossing all industrial boundaries, potential applications include the connection of Rockwell Automation processors to Modicon processors, and the connection of Modbus Plus-speaking devices, such as drives, relays, and power monitor hardware, to the Rockwell Automation backplanes.
These modules allow Rockwell Automation platforms to connect directly on Modbus Plus networks as a peer. In addition, the modules act as slaves to processors that must read/write data from the module's memory.
