What it does

Inspect register values or decode Modbus RTU and TCP frames without connecting to equipment.

Byte order

32-bit values consume two registers. Select word and byte order independently to match the device manual.

Frames

Read/write requests, read responses, write acknowledgements and exceptions are decoded. CRC and MBAP length mismatches appear as diagnostics.
