MVI56-MCM module ControlLogix processor

Description

MVI56-MCM To get the most benefit from this User Manual, you should have the following skills:

Rockwell Automation® RSLogix™ software: launch the program, configure ladder logic, and transfer the ladder logic to the processor

Microsoft Windows: install and launch programs, execute menu commands, navigate dialog boxes, and enter data

Hardware installation and wiring: install the module, and safely connect Modbus Master/Slave and ControlLogix devices to a power source and to the MVI56-MCM module’s application port(s)

The MVI56-MCM module internal database is divided into two user-configurable areas:

Read Data

Write Data.

The Read Data area is moved from the module to the processor, while the Write Data area is moved from the processor to the module. You can configure the start register and size of each area. The size of each area you configure must match the Add-On instruction controller tag array sizes for the READDATA and WRITEDATA arrays. The MVI56-MCM sample program is configured for 600 registers of READDATA and 600 registers of WRITEDATA, which is sufficient for most application. This topic describes how to configure user data for applications requiring more than 600 registers of ReadData and WriteData.

MVI56-MCM Parameter Description

Enabled 1 = ENABLE PORT, 0 = disable port

Type 0=MASTER, 1=Slave

Protocol 0 = MODBUS RTU MODE, 1 = Modbus ASCII mode

Baudrate Sets the baud rate for the port. Valid values for this field are 110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 384 or 3840 (for 38,400 baud), 576 or 5760 (for 57,600 baud) and 115,1152, or 11520 (for 115,200 baud)

Parity 0 = None, 1 = Odd, 2 = Even

DataBits Modbus RTU mode = 8 Modbus ASCII mode = 8 or 7

StopBits Valid values are 1 or 2.

RTS On 0 to 65535 milliseconds to delay after RTS line is asserted on the port before data message transmission begins. This delay can be used to allow for radio keying or modem dialing before data transmission begins.

RTS Off 0 to 65535 milliseconds to delay after data message is complete before RTS line is dropped on the port.

Use CTS Line No or Yes This parameter is used to enable or disable hardware handshaking. The default setting is No hardware handshaking, CTS Line not used. Set to No if the connected devices do not need hardware handshaking. Set to Yes if the device(s) connected to the port require hardware handshaking (most modern devices do not) If you set this parameter to Yes, be sure to pay attention to the pinout and wiring requirements to be sure the hardware handshaking signal lines are properly connected; otherwise communication will fail.
