Modbus Master/Slave Module for SLC Platform, MVI46-MCM

Type:  I/O Interface
Description:  The MVI46 Modbus Master/Slave Communication Module allows Rockwell Automation SLC processors to interface easily with other Modbus protocol compatible devices. Compatible devices include not only Modicon PLCs (which all support the Modbus protocol) but also a wide assortment of end devices. The module acts as an input/output module between the Modbus network and the Rockwell Automation backplane. The data transfer from the processor is asynchronous from the actions on the Modbus network.
Connectivity:  Modbus
Features:  Support for the storage and transfer of up to 5000 registers to/from the SLC processor's data files; User-definable memory; Two ports to emulate any combination of Modbus master or slave device; Configurable parameters include Protocol: RTU or ASCII, Baud rate: 110 to 115,200, Parity: none, odd and even, Data bits: 5 to 8, Stop bits: 1 or 2, RTS on and off timing: 0 to 65535 milliseconds, Minimum response delay: 0 to 65535 milliseconds, Use of CTS modem line: Yes or no, Device routing paths: 1 to 64; Floating-point support Slave features; Supports the Modbus function codes 1, 2, 3, 4, 5, 6 15, and 16.
Specifications:  Form Factor Single Slot - SLC chassis compatible; Backplane current load 800 mA @ 5 V; Operating temperature 0 to 60 deg C (32 to 140 deg F); Storage temperature From -40 to 85 deg C (-40 to 185 deg F); Shock 30g operational, 50g non-operational; Vibration 5 g from 10 - 150 Hz; Relative humidity 5-95% (w/o condensation); LED indicators: Module status, Backplane transfer status, Application status, Serial activity and error LED status; Configuration Serial port (CFG): DB-9M PC compatible, RS-232, Hardware handshaking; Application Serial port (PRT1, PRT2) (2) DB-9M PC compatible, RS-232, RS-422; Application Serial ports (PRT1, PRT2), RJ45 (RJ45 to DB-9M PC Compatible connector is supplied), RS232/422/485 jumper selectable, RS232 handshaking configurable, 500V Optical isolation from backplane.
