Frequently Asked Questions (FAQ)
-
What is the primary function of the 3500/25 TDI module?
The TDI acts as the system controller and data interface for System 1® software in the Bently Nevada 3500 system. -
Is the 3500/25 module compatible with other 3500 rack modules?
Yes, it is fully compatible with all 3500 series monitoring modules. -
Does this module support transient data recording?
Yes, it supports both static and transient data for comprehensive condition monitoring. -
Can it be used in redundant configurations?
Absolutely. The module supports dual TDI configurations for redundancy and reliability. -
What is the communication protocol used by the TDI?
It communicates via Ethernet using Modbus TCP/IP and interfaces with System 1® software. -
What kind of data can System 1® access through the TDI?
System 1® can access static data, transient data, alarms, and configuration settings. -
Is the 3500/25 suitable for use in hazardous locations?
Yes, the module is certified for use in hazardous areas with ATEX, CSA, and IECEx approvals. -
What firmware versions are supported by the 3500/25 TDI?
