Modbus Frame Converter

Convert complete Modbus RTU, TCP and ASCII requests or responses, with CRC/LRC validation.

How to use

Preserves the function and all PDU bytes. Converts one unicast frame at a time; no device connection is needed.

Up to 4,096 characters. RTU/TCP: whole HEX bytes. ASCII: colon followed by HEX; \r\n represents CRLF.
