  1. It's a good point we talk about in the old forum. Today I have the remote access to do it but sometimes I am so lazy...
  2. I wondered about that when I saw the Modbus Protocol first time. Maybe because I was using a lot of HMIs with that way of work. It would be a wonderful tool for newbies in communications. By the way, I've spent my three weeks of summer holidays and I can say it's not easy to work at 40ºC in the streets.
  3. 500 ms is the time of the pulses of SB3. My way: First send the value of Inputs to Memory Bits but only when you want: SB3 I1 I0 MB0 --| |--|/|--| |-----( ) SB3 IO I1 MB1 --|/|--|/|--| |-----( ) Then use MB0 and MB1 instead of I0 and I1 in your application.
  4. There is other good: One of the slave modbus is a energy meter and the manufacturer has a software to read its values. Now the V130 is a Gateway Modbus RTU to Modbus TCP too. This way the software can connect via internet (ADSL)with the remote energy meter. The application is a replication of the address RTU to TCP. The future will be to it via GPRS. A question: is possible to connect with a V130 in "Modbus TCP GPRS"??
  5. Hello, [off topic] This will be my first "real" topic in this new brand forum. I hope it will be so good as the old forum [/off topic] I finished a little project to make a Datalogger with a V130. Someone could ask: anything else? Well, it's an easy application for Unitronics but we realized that it's hard to find in the market a datalogger so open and cheap. The project is simple: 1.- To read datas from a Modbus Slave 2.- Prepare the datas 3.- Save the datas in the microSD of the V130 (In spanish you have to do some changes for the standard way to create a CSV) Easy? now go to find a Datalogger in the market with the powerful of the V130.
  6. En esta ocasión se ha aplicado un V120 de Unitronics con módulos de entrada PT100 y 4-20mA para el control y supervisión de una cámara climática dónde se realiza el curado de muestras de hormigón. El V120 ha sido programado para controlar la temperatura y la humedad ambiental mediante lazos PID o todo-nada con histéresis para calentar, enfriar y humidificar la sala. El propio equipo realiza una adquisición de datos durante el tiempo del proceso y los envía a través de una red RS485 a un ordenador central, donde los datos son almacenados en formato Excel para visualizarlos en gráficas e imprimirlos.
  7. HELLO WORLD - HOLA MUNDO Mis primeras palabras en español dentro de este foro dominado por el idioma de Shakespeare y de la automatización en general. Espero que sea punto de encuentro de la comunidad hispano-parlante y donde serán bien recibidos todos vuestros trucos y casos de éxito, al igual que espero os sirva todo lo que vaya publicando. Me gustaría recopilar en este blog trabajos realizados por todo el mundo utilizando Unitronics.
