6.2 Specifications
The MVI56E Modbus Master/Slave Communication Module with Reduced Data
Block allows users to integrate Modbus devices and networks into the Rockwell
Automation
®
ControlLogix
®
architecture.
Compatible devices include not only Modicon
®
PLCs (almost all support the
Modbus protocol) but also a wide assortment of processors, HMI displays,
SCADA systems and field devices made by a variety of manufacturers. The
module acts as an input/output module between the Modbus network and the
ControlLogix processor. The data transfers between the module and the
processor are asynchronous from communications on the Modbus network. A
5000-word register space in the module hold the data to be exchanged between
the processor and the Modbus network.
