Features and Benefits
  • The MVI56-LTQ module acts as an input/output module between the Limitorque valve network and the ControlLogix processor. The data transfer from the ControlLogix processor is asynchronous from the actions on the network. The 1500-word register space in the module transfers the valve information from the module to the processor. Ladder logic is responsible for control of the valves. Data transferred from the processor to the module instructs the module to execute commands to valves on the Limitorque network.
