If anyone would like to find out how to set up a cheaper modem to communicate with plc's give me a shout. If you need to find serial numbers for your Mitsubishi software I can guide you in the right direction. I will not give serials. Help with password recovery on Siemens and Mitsubishi PLC's. Custom VB applications via the mxcomponents or via OPC with the clientace utility. I have a registered version of Clientace and recommend it to anyone wanting to create custom VB apps. There is a cable one can make to communicate with Mitsubishi PLC's including FX2N. Works well , tried and tested. No IC's just 3 wires. I spe******e in Mitsubishi , Siemens and Delta plc's. Have moved away from HMI's as VB is so powerfull. Can do so much more than any scada or hmi. I do however recommend the Delta HMI's. They are cheap and work so well. They have scripting abilities that make them so poerfull. They have 16000 on board data registers so most of the processing can be done on the screen. better than GOT1000's or siemens OP's. I deal with many industries so my experience has touched base with many problems so give me a shout if any problems are met.
