I was using modscan software to verify I could read the registers from the slave device and I was. When all of a sudden I get a message The Mods can quit working and is going to close, it did.
After the program closed I couldn't establish communication again. I was at the device using a USB to serial cable with a null modem adapter. I tried a second MODBUS program, still no connection. What and we're could the issue be? Is the modbus software the problem or the slave device? I purchased both modbus software program, not trial freeware.
Any help would be greatly appreciated.
Thanks
