  1.   Hello everyone,   I am Nader Zouaoui an industrial engineering studen, I'm intern at a petrol terminal doing my end of study project there I happened to be working on a TWIDO PLC to be precise the twdlcaa24drf and the twdlcaa40drf.   What we aim to do is to collect the state of all the inputs at all time and send it to a computer that will log every change in the sensors state.   To that I thought about using the port 1 (the mini din used for the programming of the PLC) because that is the only one I have available.   So I wanted to know first is that even possible or not?   Second, and if so, do you have a tutorial link that you can send me on how to do it?   and third thank you very much for your help.   Best regards,
  2. We have an install base of about 120 TWIDO PLCs anywhere from 1 to 10 years old with varying configurations, but all using the TWDLCAE40DRF base unit.  Lately (over the past couple of years), we've had multiple instances where upon power being removed from the device, and then turned back on, the base unit fails and will not power back up.  The typical case is that we turn on the power, a couple of LEDs flash for a brief (< 1 Sec) moment, and then nothing - unit is dead. Just wondering if anyone else has encountered the same thing.
  3. I need solution for master & slave configuration between 2 PLC Twido TWDLCAE40DRF. My final project is about a system for filling drink on a cup and do the packaging. the component of the project is the filling system (dropping cup, filling water, pressing the seal) and the packing (packing into a box and sealing the box). This project is using 2 PLC Twido TWDLCAE40DRF. My problem is how to configure one of them as the master and the other as the slave. I've read the manual book but it's hard to understand the instruction. if anyone can give a simplify explaination to me please reply this post or you can reach me at mail: tatangprayoga11@gmail.com  
  4. ASCII Code 8 Byte In Twido

    Hey Guys!!!! I'm trying to use ASCII 8 bites in TWIDO PLC and on MOD BUS TCPIP it connected to WinCC , where I'm trying to read the ASCII in as a STRING char that to in 8bits. The problem I'm facing is that it is getting swapped like if I'm writing VA in PLC then on SCADA it is showing AV. In WinCC there is no setting for word swapping. Therefore Kindly help me for this in plc end

  7. I need to make a setup like the readings in the energy meter should be a GSM then from this GSM the data should be sent to another GSM using Twido PLC.,please help me how to establish this connection. (Energy meter ----+ Twido PLC----+GSM) data from this should go to another similar set up (GSM----+Twido PLC---+Energy Meter) I dont know is this possible or not please help me,,
