The BENTLY 3500/92 136188-01 is a critical bridge between the autonomous machinery protection of the 3500 rack and the plant's centralized control systems. While the monitors handle the safety of the machine, the 3500/92 exports real-time values, status bits, and alarm history. This allows the Distributed Control System (DCS) or Programmable Logic Controller (PLC) to incorporate machinery health into the overall plant automation strategy.
The 136188-01 hardware supports both serial and Ethernet-based communication. Its most common application is as a Modbus gateway, supporting Modbus RTU and Modbus TCP/IP protocols. This versatility ensures that the 3500/92 can be integrated into both legacy serial networks and modern fiber-optic plant backbones. The module supports high data throughput, ensuring that the control system receives updates within milliseconds of a change in machine state.

Using the 3500 Rack Configuration Software, users can create custom Modbus maps. This allows engineers to select exactly which data points—such as vibration amplitudes, thrust position, or temperature—are sent to the external controller. This selective mapping optimizes network bandwidth and ensures that only relevant information is displayed on the operator's central console.
In critical power and oil & gas applications, communication redundancy is often required. The 3500/92 supports redundant configurations, where two 136188-01 modules can be installed in a single rack. If the primary module fails, the secondary gateway automatically takes over the communication tasks, ensuring that the plant operators never lose visibility of their most valuable rotating assets.
The 136188-01 is built for the long haul. It features high-grade electrical isolation to protect the rack backplane from network-borne surges. Its rugged construction and extensive testing ensure that it meets the global standards for machinery protection systems, providing a reliable digital link for the life of the machine.
