R.Mozes Posted December 19, 2012 Report Share Posted December 19, 2012 Hello, It seems that indeed the BinLib version cause to this issue. Please try to recover the PLC as follow: Use COM1 RS232 115200 baud rate 2sec time out Connect 6 wire cable instead of the 4 wire cable. Reboot the PLC The PLC should beep > tap once to stop the beeping Go to VisiLogic>communication & O/S, the 4th tab is system modes Check the communication by clicking on the GET button If you have a communication>Switch to Factory BOOT Go to O/S tab>check Download only the BinLib by clicking on the Advance button>BinLib (only) If the download will success, then replace to 4 wire back and download the BOOT and then the O/S. 1 1 Link to comment Share on other sites More sharing options...
d7branko Posted December 20, 2012 Author Report Share Posted December 20, 2012 I don't know how to thank you Mozes...... It worked but not with a 6 wire cable....As you said direct RS232, till now I was using USB to RS232 and losing the communication all the time....I went to a friend and with an older PC and built in RS232 port.... Saved it.... Now it's working as a charm.... THANKS.... Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted December 21, 2012 MVP 2023 Report Share Posted December 21, 2012 The topic of the quirky USB->serial converter has been brought up before, but it's worth mentioning again. I did a project this year integrating our standard converter (MJ10-22-CS35 using the Prolific PL2302 chipset) into a test and data acquisition system running tests on appliances. This converter usually works fine but is not isolated and if there is a ground potential difference between the PLC and the computer the converter is plugged into then all kinds of intermittent gremlins get into the system, resulting in communications failure. I swapped out the converters to isolated ones recommended by Walkerok - part number USB-COMi-M available at several online sources. These are more expensive than ours but work extremely well. I've had no problems since I swapped them out. Joe T. 1 Link to comment Share on other sites More sharing options...
