Hi,
I am using the Hakko V706MD HMI with a DU01 ethernet expansion and am having problems using the Modbus tables. As you may know you need to set $s800 to the value of the modbus table that you are using (there are 255 tables). We are using Kepware as the master and the Hakkos as the slaves. If a machine goes down (power fail, etc.) the $s800 reg goes to -1 (65535) and all of my devices that are in modbus tables go bad. I can do a synchronous write in the kepware OPC quick client and move 0 into $s800 (which is the table I am using) but the values remain bad until I close the client and reopen it. This also happens in Excel if I loose the data due to $s800 <>0 then I write 0 into a DDEpoke VB command (which changes $s800) but the data doesnt refresh until I close Excel and restart. I have tried to update links in the Edit-link tab but that doesn't work. All of the data coming from the Hakko $u and $s registers is correct on start up it is only the PLC data that I have on the Modbus tables that doesn't refresh. Any help would be most benificial.
Regards,
Darren
