Description
Product details:
The ProSoft MVI56-S3964R is a protocol module that acts as a Siemens 3964R network interface module. ProSoft Technology manufactures this protocol module for point-to-point communication capabilities between any ControlLogix processor such as a 1756-L1, 1756-L1Mx, 1756-L55, or 1756-L6x, and any other device with Siemens 3964R communications. Basically, it enables communication between Allen-Bradley PLCs and Siemens devices, since the 3964R protocol was invented by Siemens. Prosoft MVI56-S3964R essentially adopts point-to-point protocol with read and write functions. It performs a BCC checksum to ensure the security of the transmission. The device communicates with the device using two independently working RS-232 or RS-422 communication ports.
application
This module is ideal for control configurations that require the ControlLogix processor to exchange data with other non-Rockwell Automation control devices in low-speed applications.
MVI56-S3964R can use two RS-232, RS-422 communication lines (ports) to communicate with the device. These ports operate independently of each other.
Specification
Single Slot – 1756 Backplane Compatible
The module is recognized as an input/output module and can access processor memory to transfer data between the processor and the module
Ladder logic is used for data transfer between the module and the processor. Contains example ladder diagram files.
Configuration data obtained from the configuration text file downloaded to the module. Contains sample configuration files
local or remote rack
Single slot, ControlLogix backplane compatible
Multiple modules can be placed in one rack up to chassis power limitations
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 communication partner
In 3964R without RK512 mode on PRT1 and PRT2, data can be sent from ControlLogix processor or received from communication partner
Maximum transfer size in any mode is 512 bytes
Data byte swapping can be configured to accommodate different word formats
In 3964R in RK512 mode on PRT1 and PRT2, header information DB (data block), DW (data word) and coordination bytes 9 and 10 can be evaluated
Communication activity and diagnostics available via LEDs and acknowledgment telegrams
