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.

Prosoft Technology
Specifications
  • Single Slot - 1756 backplane compatible
  • The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
  • Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
  • Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
  • Local or remote rack
  • Single-slot, ControlLogix backplane compatible
  • Multiple modules can be placed in a rack up to the chassis power supply limit
  • While in 3964R with RK512 mode on PRT1 and PRT2, DB-SEND and DB-FETCH instructions can be initiated from the ControlLogix processor or received by the communications partner
  • While in 3964R without RK512 mode on PRT1 and PRT2, data can be sent from the ControlLogix processor or be received from the communications partner
  • The maximum transfer size is 512 bytes in any mode
  • Data byte swapping can be configured to adjust to a different word format
  • While in 3964R with RK512 mode on PRT1 and PRT2, evaluation of the header information DB (data block), DW (data word) and coordination bytes 9 and 10 is possible
  • Communication activity and diagnostics are available through LEDs and acknowledgment telegrams
Applications
  • 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.
Features and Benefits
  • 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.
Ladder Logic
  • 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.
