Problems when reading Input 5 to 8 of the PCD7.L100/L200

FAQ #100887

Reading Input 5 to 8 of the PCD7.L100/L200 leads to a NAK response.

 

Problem
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.
Reason
These status can only be read as Output.
Solution
Instead of Display Input you have to use the Display Output command and it will work
