52.1  Examples

 

Function code 52 is commonly used with function codes 13 and 24 to dynamically modify integer parameters. Figure 52-1 is an example of how to use the manual set integer to change the set point  tracking option in a station. The value in the remote control memory block (function code 62) determines which input the function codes 13 block reads (<S3> equals zero for <S1>, and <S3> equals one for <S2>). The adapt block (function code 24) adapts S30 of the control station (function code 80) to the value received from the integer transfer block (function code 13). When the S3 input (output from the remote control memory) equals zero, the output of the integer transfer block equals its S1 input (one). Thus, S30 of the station adapts to set point track option one (track the process variable).
