Manufactured by ProSoft Technology, the MVI69-S3964R module is a Siemens 3964R network interface module classified under the CompactLogix series of modules. The MVI69-S3964R module is a single-slot network interface designed to function with the Ladder Logic Data Transfer protocol. The unit comes with a maximum transfer size of 512 bytes and it features a 2-power supply distance rating. It features the standard 1769 single-slot module with a current load of 800 mA maximum at 5 Volts DC. The MVI69-S3964R module is installed in the application chassis and it uses the protocol types known as the serial RS-232, 485, and 422 types. The MVI69-S3964R module features local rack installation. The MVI69-S3964R module features bi-directional data communication with the point-to-point connection type. It comes with a read and write capability and the peer-to-peer protocol. The unit is recognized as an I/O module and it comes with access to the processor memory for offering effective data exchange between the application and the module.

The ambient operating temperature range for the MVI69-S3964R module is 0 to 60 degrees Celsius. For prolonged machine life, ensure that the storage temperature is between -40 and 85 degrees Celsius. The MVI69-S3964R module features LED indicators for effective monitoring of the communication activity and delivering diagnostics. The LED indicators show the unit’s battery and module status, the application’s status, and serial port activity and it allows for the monitoring of the CFG port activity. The MVI69-S3964R module ladder logic programming enables the unit’s protocol functionality through handling the encoding and the decoding functionalities and delivering the initiation of the protocol-specific functionalities in the module.
