SST 5136-RE-VME communication interface module
SST 5136-RE-VME is an intelligent communication interface module designed for high-speed data exchange between a VMEbus host and Reliance Electric R-Net (or Remote I/O) networks.
Originally developed by SST (now part of Molex), this 6U VME card is a critical component for integrating Reliance Electric AutoMax systems with VME-based industrial computers.
By utilizing an onboard processor, the 5136-RE-VME offloads the complex R-Net protocol timing from the VME host,
ensuring deterministic performance in high-speed motion and process control applications.

Maintenance
Status LEDs: Monitor the “SYS” (System) and “NET” (Network) LEDs. A solid green light indicates normal operation; flashing red typically indicates a configuration mismatch or cable fault.
Airflow: Ensure the VME rack’s fan assembly is operational, as the high-density components on the 5136-RE-VME generate significant heat during continuous operation.
Backup: Maintain a copy of the binary configuration files used to initialize the card via the host software.
Unique Product Description
The SST 5136-RE-VME is the “Missing Link” for facilities running Reliance Electric infrastructure.
While many communication cards require complex driver overhead, the 5136-RE-VME uses a Dual-Port RAM architecture that simplifies the interface for the programmer.
It effectively treats the entire Reliance R-Net network as a block of local VME memory, making it the most efficient solution for real-time control and high-speed data acquisition in specialized industrial environments.
