Hello, I'm experiencing a strange behavior with Logo 8.3 as Modbus server. The client is an Arduino board configured to access the first 8 HR regs, writing the last 4 of them respectively with 1111, 2222, 3333 and 4444 values. I have configured program and modbus data transfer on Logo as shown in f1.png whilst display is configured as shown in f5.png. Everything works fine as shown on the display (f2.png). As soon as I try to reconfigure data transfer as shown in f3.png, I get a strange result as shown in f4.png. According with the new data transfer config, I expect to get the first value (VM 18) only while the remainig 3 values should be zero since they are no more mapped to old VMs. I get instead the opposite: I cannot see the first value anymore while I still see the last three ones! What's wrong in my consideration?
