Dear Mr. Thanks for trying to help Me. I have done the following to send the frame F1 00 36 10 10 01 47 I put MI50 = F1; MI51 = 00 , MI52 = 36, MI 53 = 10, MI 54 =10 , MI55 = 01 MI56 = 47.On the PC, I'm seeing that the right data send by the PLC. F1 00 36 10 10 01 47 But when connecting PLC - Power Supply , it is not responding. I have reviewed the communication parameters of PC, PLC and source and are the same (38400 bps, odd, 8, 1). To send Parametres PC - Power Supply, I do it through Docklight program. I attach the following: 1 .-Images of Visilogic program. 2.-Image of Physical Connection PLC / Power Supply. 3 .- Protocol of the Power Supply. Serial Card. Please see the page 4 or 24 . The card that I am using is IF-R2. (DB9 port) 4.- Dockligth command file.(basic.txt). Please to open change basic.txt by basic.ptp The dockligth http://www.docklight.de/ can be downloadedthanks for all.regards.Dantty <br class="Apple-interchange-newline"> Basic.txt unitronics_problem.doc manual.pdf

Thanks for you awswer.. I have doing that You show on the picture. But i do not have any response of the power supply. Because IT is send by ASCCI way. I need to send to binary way...i that possible.?

Joe I am Sorry I have made the changes. Miguel

Hi Everybod Please can you help me with the following. I have a vision 570 OPLC which must command an adjustable voltage Power Supply through of serial port on RS232. The Power Supply has its own proprietary protocol, so I'm using FB protocol, to send through the block, to assemble the frame Exactly I need to send is F1 00 36 10 10 01 47. Before checking Power Supply - PLC communication, I have verified PLC-PC communication and PC get exactly what PLC is sending... F1 00 36 10 10 01 47 however when I try to communicate PLC-Power Supply , it is not responding (I'm sending the command to put it in remote mode).> I consulted the provider of the power supply and I responded as follows: "The PLC or a PC can send data over COM port either binary or as ASCII. I think you are sending ASCII. It means, F1 00 36 10 10 01 47 is sent as a string of ASCII bytes, not binary bytes. In ASCII, the value 00 for example is sent as two binary bytes 30 30, so the number of bytes in the message actually doubles" Anyone know how to do that in UNITRONICS.? how to send data in binary form in UNITRONICS PLC.?
