Siemens S3964R Protocol Communication Module
MVI69-S3964R
The MVI69-S3964R module from ProSoft Technology allows point-to-point communication between a CompactLogix or MicroLogix controller and a partner with 3964R (with or without RK512) communication capability.
Features and Benefits
The 3964R protocol (with or without RK512) 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.
Applications
The module is ideal in control configurations where there is a need for the CompactLogix controller to exchange data with other non-Rockwell Automation control devices in low speed applications.
The MVI69-S3964R can communicate with or without RK512 devices using two RS-232, RS-422 communication lines (ports). The ports operate independently from each other.
Functional Specifications
Single-slot, CompactLogix 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 CompactLogix processor or received by the communications partner
While in 3964R without RK512 mode on PRT1 and PRT2, data can be sent from the CompactLogix processor or be received from the communications partner
The maximum transfer rate 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
Ladder Logic
Ladder logic programming in the CompactLogix 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 ease the implementation of the module in the user application.
