The choice of the RS-485 physical standard was made due to its ability to transmit data over long distances in multipoint connections within a serial network, suitable for different devices and considering environmental interference conditions. Communication between PLCs was established using the N: N communication protocol, which facilitates the exchange of data between the master device and the slave. An important configuration of the protocol is the transmission rate, which is adjusted to perform communication tests and verify response times at different rates. Communication tests have shown that there is a direct relationship between baud rate and reaction time, indicating an improvement in communication as the baud rate increases. The analysis revealed that, at a rate of 1200 baud, the delay time is considerably high, reaching 310 milliseconds. This level of latency may be acceptable for applications where response time is not critical, as we increase the speed to 9600 baud, we see a significant improvement in lag time, dropping to 254 milliseconds. The maximum speed analyzed is 19200 baud, where a delay time of only 94 milliseconds is recorded. This dramatic improvement in latency is critical for real-time applications where control systems rely on fast data reception and processing. |
