Problems when reading Input 5 to 8 of the PCD7.L100/L200
Reading Input 5 to 8 of the PCD7.L100/L200 leads to a NAK response.
The status of the manual switch from channel 1 to 4 is stored in addresse 5 to 8 of the PCD7.L100/L200. When trying to read this addresses as input from the debugger or OPC server a NAK response is returned from the PCD instead of the status.
These status can only be read as Output.
Instead of Display Input you have to use the Display Output command and it will work
PCD7 / Lxxx
