Modbus

Have you ever needed to analyze a Modbus RTU message. The CAS Modbus RTU parser can analysis a Modbus RTU message and tell you if there are any errors in the message, what type of messages it is, what data is being written or read from your device, what device the message came from.

CAS Modbus Scanner is a utility to read/write coils, inputs, holding registers, and input registers from a Modbus enabled device. Values retrieved from the device can be viewed in many different formats including Binary, HEX, Uint16, Int16, Uint32, Int32, and Float32. The utility support multiple...

CAS Modbus Explorer is a utility to discover Modbus devices on a Modus RTU network. If you dont know the connection settings or the device address then this is the utility for you. It tries all combinations of Baud, Parity, Data Bits and Stop Bits & all Addresses in the range you specify.
