The MVI56 S3964R Protocol module from ProSoft Technology allows point-to-point communication between a ControlLogix processor (1756-L1, -L1Mx, L55, L6x) and a partner with 3964R communication capability.
The 3964R protocol was designed by Siemens for bi-directional data communication through a point-to-point connection. It is a peer to peer protocol with read and write access. A BCC checksum ensures the safety of the transfer.
The module is ideal in control configurations where there is a need for the ControlLogix processor to exchange data with other non-Rockwell Automation control devices in low speed applications.
The MVI56-S3964R can communicate with devices using two RS-232, RS-422 communication lines (ports). The ports operate independently from each other.
Ladder logic programming in the ControlLogix processor is required in order to enable and support the Siemens 3964R protocol functionality. The ladder program handles the encoding/decoding of data transferred from the module as well as the initiation of protocol-specific functionality in the module. Example ladder programs are provided with the module to simplify the implementation of the module in the user application.
