5.1 Product Specifications
The MVI56 Teledyne CA Slave Module allows ControlLogix I/O compatible
processors to interface easily with TCA protocol compatible devices.
5.1.1 Features and Benefits
The MVI56-CAS module acts as an input/output module between the TCA
network and the ControlLogix backplane. The data transfer from the ControlLogix
processor is asynchronous from the actions on the TCA network. A 5000-word
register space in the module exchanges data between the processor and the
TCA network.
5.1.2 General Specifications
ƒ Single Slot - 1756 backplane compatible
ƒ Local or remote rack
ƒ The module is recognized as an Input/Output module and has access to
processor memory for data transfer between processor and module
ƒ Ladder Logic is used for data transfer between module and processor.
ƒ Configuration data obtained through user-defined ladder. Sample ladder file
