If you want to calculate elapsed time you can use the UTC time instead RTC, UTC is in seconds, this way if you substract the start value of the end value you will get the elapsed seconds.

Hello Phil, I'm using Autohotkey (I'm very newbie) I don't have the skills to use with Visilogic. Can you explain a little more about it.

Thanks Malcolm but this is not my target. I have other projects with Ewon modem-router instead of a simple modem GPRS. The question is if I can use the V130+modem gprs like a Modbus TCP/ip slave

I hope don't lose the old forum, it's almost the wikipedia of Unitronics gurus.

It's true, not all usb-serial work with Jazz but they work with others Unitronics OPLCs. I have some customers had to buy the recomended Unitronics' converter.

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...

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.

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.

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"??

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.

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.

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.
