Comidoc Analysis
Protocol-centric Modbus and RS485 training
Strengths
Granular Protocol Mechanics
Instruction covers the specific mechanics of the Modbus protocol, including byte notation, unit IDs, and function codes to aid troubleshooting.
Software-Led Simulation
One sampled review suggests that learners can observe data traffic using virtual serial ports and simulation tools like Modscan32 and Modsim32 on a PC.
