Dear Joy Good Morning Thanks for the Reply, OK I Got it. and How to Calculate SUM 8 Check SUM For The String Example : I sent "9901029999FF" From Terminal Program Simulator & Received IN V700 PLC in HEX Format as follows MI1310=3939;MI1311=3130;MI1312=3230;MI1313=3939;MI1314=3939; & MI1315=4646; Should I Split Each Byte & SUM it, Like{39+39+31+30+32+30+39+39+39+39+46+46},If Yes How Should I Split into Separate Bytes in Visilogic Ladder OR Should I SUM all My Integer Variables Like {MI1310+MI1311+MI1312+MI1313+MI1314+MI1315=MI1316}

Dear Joe Good Morning to you I am Waiting for Reply for above as well Sample Serial Communication Program with how to use Checksum in both Send & Receive Situations may be SUM8 /CRC. Thanks
