What Modbus address would we need to put into the MODSIM32 simulator if we specified on the MVI56-MCM device address to 8680HEX (-31104 decimal) when the MVI56-mcm is the slave?

The negative value display on the ControLogix is due to the format of the data, 15bits +one sign bit. Set a value of 34432 into MODSIM32. Use a calculator to convert the value from 8680 hex to decimal, 16bits = 34432.
