andrewjfox Posted November 16, 2011 Share Posted November 16, 2011 Hi, I have a ethernet server device running MB TCP in DF, and am able to read the registers OK using QuickMod as MB client, but am unable to set registers from QuickMod. See attached screen shot for error message. The server DF and QuickMod are running as separate instances on same machine, and I have DF Pro license on USB hardware key. 1. Are there any read/write limitations on channels that have a MB slave address? 2. Can I have 2 channels with same MB slave address, 1 for reading, 1 for writing (since I have to do this in channels to talk to MB slave (DF as client) I figured it would be the same for MB slave) If this should work, do you have any troubleshooting tips?
