Type:  Software - Testing and Simulation
Description:  The DLM400 is a window/data spy into all requests and response frames passing between two or more devices on a serial Modbus circuit. It supports RS-485, RS-422, and RS-232. Additionally, the DLM400 supports MIL-Std-188-114 monitoring, testing, and RS485 simulation. Analyzer is small, battery-powered, light weight and portable.
Connectivity:  Modbus, Modbus TCP
Features:  Sees Modbus data requests and data responses between client and server; provides a neutral evaluation platform to discover failures and invalid responses or requests; can act as server on a 485 bus; can record and retransmit Modbus frames; can upload observed frames to a PC for documentation
