Pitfall to be Avoided Comparisons between variables (bytes and signed words) and immediate values are a frequent source of errors. Example Var.B == 128. 0xFF 4 - 8 en-938846/5 Propagation of register bit 7 0xFF 0xFF 0x80 Var.B = = 128 1 0 0 0 0 0 0 0 Immediate value Register D0 (on 32 bits) 0x00 0x00 0x00 0x80 Register D1 (on 32 bits) Variable Var.B is never equal to immediate value 128. The equality can be achieved using a mask and writing Var.B & OxFF == 128. 0xFF 0x00 0x00 0x00 Propagation of register bit 7 0xFF 0x00 0x00 0x00 0xFF 0x00 0x00 0x00 0x80 0xFF 0x80 0x80 Var.B & 0xFF = = 128 D0 ! = D1 1 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 Register D0 (on 32 bits) Register D1 (on 32 bits) D0 & D1 -> D0 Register D0 (on 32 bits) Register D1 (on 32 bits) D0 = = D1 Immediate value
4.5.8 Overflow - Sign Change Literal Elements of Ladder Language The system does not perform overflow <strong>control</strong>. It is therefore up to the programmer to take the necessary precautions. Example of Sign Change: %M100.B and %M101.B are two byte variables both equal to 0x7F (i.e. +127). The assignment: %Var.xx = %M100.B + %M101.B gives: 0x00 0x00 0x00 Propagation of register bit 7 0x00 Propagation of register bit 7 0x00 0x00 %M100.B (0x7F) + %M101.B (0x7F) = = Var.xx 0 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 Var.B is loaded with 0x00FE. Since bit 7 (sign bit) is a 1, Var.B == -2 (wrong answer) 1 1 1 1 1 1 1 0 Var.W is loaded with 0x00FE. Since bit 15 (sign bit) is a 0, Var.W == 254 (right answer) Var.L is loaded with 0x000000FE. Since bit 31 (sign bit) is a 0, Var.L == 254 (right answer) 0x00 4.5.9 Examples of Literal Entities 0x00 0x00 0x00 0x7F 0x7F 0xFE 0 0 0 0 0 0 0 0 0x00 Register D0 (on 32 bits) Register D1 (on 32 bits) D0 + D1 -> D0 Result D0 (on 32 bits) 0x00 1 1 1 1 1 1 1 0 Comparisons: - %M5.B + %V33.L == %M10.W, - (Var_1
