FC 13 - Integer Transfer

This function provides a means for switching integer values. When <S3> equals zero, the output equals <S1>. When <S3> equals one, the output equals <S2>.

 

NOTE: This is different from the analog transfer (function code 9), which has an optional transfer time feature.

13.1 Applications

A common use for function code 13 is to dynamically modify integer parameters. Figure 13-1 illustrates using function code 13 with function codes 52 and 24 to change the set point tracking option in a manual/auto station. An output from a remote control memory (RCM) block (function code 62) to <S3> of function code 13 determines which input (zero for <S1> or one for <S2>) is sent to the adapt block. Function code 24 adapts <S30> of the (function code 80) to the value received from the function code 13 block.

 

For example, when the output of the RCM equals zero, the output of function code 13 equals <S1> (one) causing <S30> of the control station to be adapted to set point track option one (track the process variable).
