: Only the master can initiate a query. It requests data (like coil status or holding register values) or sends commands to the slave.

refers to the process of using software libraries—primarily the National Instruments (NI) Modbus Library for LabVIEW —to initiate communication requests from an Ethernet-based master device to slave controllers . Overview of MB Ethernet Master Query mb ethernet master query download

In industrial automation, an (now often called a "client") initiates transactions by sending queries to slave devices (or "servers") over a TCP/IP network. The "MB Ethernet Master Query" is a specific set of Virtual Instruments (VIs) within the NI Modbus Library designed to handle these requests. : Only the master can initiate a query
