Slave device reported an exception - 1 - Illegal Function
GoogleCodeExporter opened this issue · comments
Using ClearSCADA or ModScan as a Modbus master to the an arduino running a
slightly modified version of the example Modbus slave programme to add a few
more registers (only 5 in total).
What steps will reproduce the problem?
1. Configure a Modbus analogue output point in ClearSCADA/ModScan and configure
it with a valid address.
2. Send a control request to modify the value from the master.
3. Arduino (slave) sends back command failed.
What version of the product are you using? On what operating system?
Windows 7
I can read this point fine from the master, it's just the control that is
erroring.
Have control functions been implemented in this library?
