When I use while … Do program control operation I cannot execute PLC Sim V13, I see an error "The device cannot support break point". Best Regards...

I was going down the wrong path as I thought breakpoints were possible on S7-1500 with TIA v13 but it looks like that I think it needs TIA v15 and S7-1500 v2.5 But I'm not certain what you're trying to do. You can use SCL with S7-1200 and simulated using PLCSIM. You do not need S7-1500 and I'm not clear on breakpoints, are you getting the error when you try to set a breakpoint or are you getting the error without setting any breakpoints? I'm not quite following your entire scenario.

I wanted use only While .. Do loop but when I used while do, PLC sim did bot work. Kal.A Thanks Mert.

TIAP V13 without service pack or TIAP V13 with service pack. V13 SP1 had big changes from the normal V13. Especially true for the simulator - PLCSIM was given with STEP7 and it could simulate S7-1200 PLCs. BUT it must be firmware V4.0 and higher. PLCSIM V13 (without service pack) might have some troubles - for that I am not sure. + Which V13 doe you have? + What happens if you use a REPEAT instruction instead? @Kal.A - sorry for answering when Mert was talking to you.

Now which TIA version supports that firmware is something I do not recall but you can very quickly find out for yourself. On the other hand PLCSIM Advanced does not simulate S7-1200 not matter the firmware version.

I used this command on both TIA V 13 SP1 and TIA V16 by selecting a 1500 PLC but when I used while .. do instruciton PLC sim does not work. unknown user WHILE #Output > 5 AND #Output < 20 DO #input_int := #input_int + #increment_1 ; END_WHILE; WHILE #Output > 20 AND #Output < 40 DO #input_int := #input_int + #increment_2 ; END_WHILE; WHILE #Output > 40 AND #Output < 60 DO #input_int := #input_int + #increment_3 ; END_WHILE; WHILE #Output > 60 AND #Output < 80 DO #input_int := #input_int + #increment_4 ; END_WHILE; WHILE #Output > 80 AND #Output < 100 DO #input_int := #input_int + #increment_5 ; END_WHILE; WHILE #Output > 0 AND #Output < 5 DO #input_int := #input_int - #increment_1 ; END_WHILE; #input_int := LIMIT(MN := 0, IN := #input_int, MX := 27648); #input_real := NORM_X(MIN := 0, VALUE := #input_int, MAX := 27648); #Channel_output_1 := SCALE_X(MIN := 0, VALUE := #input_int, MAX := 1000); instead of while .. do instruction when I use IF command like below the plcsim works perfect. unknown user IF #Output > 5 AND #Output <= 20 THEN #input_int := #input_int + #increment_1 ; END_IF; IF #Output > 20 AND #Output <= 40 THEN #input_int := #input_int + #increment_2 ; END_IF; IF #Output > 40 AND #Output <= 60 THEN #input_int := #input_int + #increment_3 ; END_IF; IF #Output > 60 AND #Output <= 80 THEN #input_int := #input_int + #increment_4 ; END_IF; IF #Output > 80 AND #Output <= 100 THEN #input_int := #input_int + #increment_5 ; END_IF; IF #Output > 0 AND #Output <= 5 THEN #input_int := #input_int - #increment_1 ; END_IF; #input_real := NORM_X(MIN := 0, VALUE := #input_int, MAX := 27648); I think the problem is due to using while .. do intruction or I may use it wrong. Best regards.
