Abierto al p\u00fablico, libre de restricciones de derechos de autor y f\u00e1cil de implementar y administrar, Modbus se ha convertido en un destacado protocolo de comunicaci\u00f3n industrial est\u00e1ndar y ampliamente utilizado. Utilizado para la comunicaci\u00f3n entre dispositivos electr\u00f3nicos industriales. Modbus es simplemente un marco de protocolo; Tambi\u00e9n existen otras versiones, como Modbus RTU y Modbus\/TCP.<\/p>\n\n\n\n<p>Modbus RTU adopta se\u00f1ales diferenciales EIA-485 (o RS-485), lo que ofrece fuertes capacidades antiinterferencias de ruido. La siguiente tabla proporciona una comparaci\u00f3n entre los protocolos de comunicaci\u00f3n existentes de MEAN WELL. La principal diferencia con el bus CAN es que el protocolo Modbus RTU emplea una arquitectura maestro\/esclavo, por lo que no admite comunicaci\u00f3n entre hosts m\u00faltiples.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"562\" src=\"https:\/\/meanwellshop.mx\/blog\/wp-content\/uploads\/2024\/06\/image-1-1024x562.png\" alt=\"\" class=\"wp-image-1316\" srcset=\"https:\/\/meanwellshop.mx\/news\/wp-content\/uploads\/2024\/06\/image-1-1024x562.png 1024w, https:\/\/meanwellshop.mx\/news\/wp-content\/uploads\/2024\/06\/image-1-300x165.png 300w, https:\/\/meanwellshop.mx\/news\/wp-content\/uploads\/2024\/06\/image-1-768x421.png 768w, https:\/\/meanwellshop.mx\/news\/wp-content\/uploads\/2024\/06\/image-1.png 1066w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>NOTA: La distancia de comunicaci\u00f3n de MEAN WELL PMBus se verifica a 100 KHz, el bus CAN se verifica a 250 Kbps y Modbus RTU se verifica a 115200 bps.<\/strong><br><\/figcaption><\/figure>\n\n\n\n<p>MEAN WELL ha introducido Modbus RTU en sus l\u00edneas de productos de fuentes de alimentaci\u00f3n digitales de alta potencia y fuentes de alimentaci\u00f3n de seguridad, como se muestra en la siguiente tabla.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><\/td><td>Modelos Compatibles<\/td><\/tr><tr><td>MODBus-RTU<\/td><td>DRS-240\/480  \\  SHP-10K-MOD<br>SHP-30K-MOD \\  HEP-2300-MOD<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>SHP-30K es una fuente de alimentaci\u00f3n digital programable que admite comunicaci\u00f3n Modbus RTU.
