MVI56E-MNETCR ♦ ControlLogix Platform
Modbus TCP/IP Multi-Client Enhanced Communications Module for Remote Chassis
Like Event Command blocks, Command Control blocks place commands into the
module's command priority queue. Unlike Event Command blocks, which contain
all the values needed for one command, Command Control is used with
commands already defined in the MNET Client x Command List.
Commands in the MNET Client x Command List may be either enabled for
routine polling or disabled and excluded from routine polling. A disabled
command has its bit in the MNETCR.CONTROL.WriteCmdBits controller tag set
to zero (0) and is skipped during routine polling. An enabled command has its bit
in the WriteCmdBits controller tag set to one (1) and is sent during routine
polling. However, Command Control allows any command in the predefined
MNET Client x Command List to be added to the command priority queue,
whether it is enabled for routine polling or not.
Command Control also gives you the option to use ladder logic to have
commands from the MNET Client x Command List executed at a higher priority
and out of routine order, if such an option might be required in special
circumstances.
A single Command Control block request can place up to 16 commands from the
MNET Client x Command List into the command priority queue.
