Operating System
The 1756-MVI module allows the user to develop C language code to
support the transfer of serial data to/from three serial ports, as well as
the transfer of 16-bit, 32-bit, float, and ASCII characters between the
ControlLogix processor and the MVI.
The MVI sits as a target device on the ControlLogix backplane and will
accept CIP connections from an originator based on the "generic
module" profile. The MVI can be configured with an I/O module
connection for scheduled (Class 1) data transfers up to 496 bytes
to/from the 5550 processor. The MVI supports unscheduled (class 3)
data transfers up to 478 bytes generated from MSG (message)
instructions in the 5550.
