You can use ladder diagram (sample below base on RSLogix5000) EQU Value_A Value_B MOV Value_A Value_C Or for function block: Use EQU with Source A is Value_A, Source B is Value_B, output of this EQU to connect to EnableIn of ADD (from ADD, select properties and tick EnableIn). From ADD block, Source A is Value_A, Source B is 0 and destination of ADD block is Value_C. Every time output of EQU in true condition will Enable ADD block and Value_C = Value_A + 0 Try it and Ihope works. Dave
