The Slave Address table that Joe posted is part of the Help page I asked you about. Rather than do screenshots I thought it would be wise for you to know the page location for an indepth read. Help generally has all the info one needs, but sometimes does need deep digging. cheers, Aus -
Hello Yes, I have fully read it and that is why I had my questions about Modbus. In the meanwhile, I was able to get out the needed information by misregarding the text about adding 30000 or 40000 to the vector address (which is simply not true because by using the different Modbus commands there is nothing to add). So, ReadCoils(4001,2) works. And so does ReadDiscreteInputs(4001,2) giving the same result. The same is true for ReadCoils(5001,2) and ReadDiscreteInputs(5001,2). And that is a bit confusing as ReadDiscreteInputs is supposed to be available to read inputs, while ReadCoils is for setting and reading outputs. But anyway, the good news is that it works! Thanks for your reply! -

@BastianPIA - You've followed the example to configure the Jazz for Modbus serial communications. I don't think this is what you want. Look in the Help for Modbus and click on the link for Modbus/TCP -> Ethernet: Jazz 2 only. You'll see there is a dialog box specifically for Ethernet communication setup. Joe T. -

Inputs start at Modbus address 04000 on a Jazz. Have you tried ReadCoils(4002),2 ? Joe T. -
Have you fully read the entire Help file listed as MODBUS in U90 Help index? cheers, Aus
