dmt (Customer) asked a question.
Using Modbus TCP. How fast can I send modbus commands to a P3-550 from Arduino?

Unfortunately there is no hard number we can provide. Scan time will be the biggest factor. The longer the scan, the slower the responses. Scan time is completely dependent upon the application: what I/O you have, how much communications are occurring, how much code you have and the type of code you have (Boolean instructions are fast, math is slow…).
