Functional Description

125736-01 is a Communication Gateway I/O Module developed by Bently Nevada. It functions as a ModbusRS232/RS422 I/O Module. With the exception of the primary value Modbus registers, it supports the original 3500/90's communication interfaces, communication protocols, and other features. Itincludes a Configurable Modbus Register Utility, which can provide the same functionality that the primary value Modbus registers did.

Features

• The Modules support extensive communication of all rack monitored values and statuses for integration with process control and other automation systems via Ethernet TCP/IP and serial (RS232/RS422/485) communications.
• It can also communicate over Ethernet with 3500 Rack Configuration Software and Data Acquisition Software. The RJ45 Ethernet connection is for 10BASE-T star configuration Ethernet networks.
• With the exception of the primary value Modbus registers, the 3500/92 supports the original communication interfaces, communication protocols, and other features.

Outputs

• OK LED Indicates when the system is operating properly.
• TX/RX LED Indicates when the system is communicating withother modules in the 3500 rack.

Features:

• TCP/IP Capabilities on Ethernet
• Capabilities for serial communications (RS232/RS422/RS485)
• Ethernet RJ45 Connection
• Modbus Register Configurable Utility

Input Data Types

• Data from other modules in the rack is collected via a high-speed internal network, such as current measured values with time stamps, module statuses, and current alarm statuses. The exact data types returned are determined by the module type and channel configuration.
• Update Time: The data collection rate is determined by rack configuration, but it will not exceed one second for all modules in the rack.

Protocol

BNC Host Protocol

• TCP/IP communication with 3500 Configuration Software and Data Acquisition and Display Software.

Modbus

• According to the AEG Modicon PI-MBUS-300 Reference Manual. Transmission mode is Remote Terminal Unit (RTU).

Frequently Asked Questions

What is 125736-01?
It is a Communication Gateway I/O Module developed by Bently Nevada.

What does the OK LED indicate?
The OK LED is designed to indicate whether the device is operating properly. When the LED is lit or flashing, it signifies that the it is functioning correctly.

What is the purpose of the TX/RX LED on the module?
The TX/RX LED serves as an indicator for communication between the system and other modules within the rack. When this LED is illuminated or flashing, it indicates that the it is successfully communicating with the other modules.

What is the BNC Host Protocol?
The BNC Host Protocol is a communication protocol used for exchanging data between the Configuration Software and Data Acquisition and Display Software and the system over Ethernet TCP/IP.
