Forum SCALE and UNSCALE - Can use FC105 (0-20mA) in your sample project for AI (0-10 V)?

1-Can I use FC105 (0-20mA) in your sample project for AI (0-10 V)?... but if my card in configurable (0-20 mA or 4-20 mA) use only FC105 for both type of current (0-20 mA and 4-20 mA) ... I attached also a project with a version for S7-1200 of the S7-300/400 FC105 / 106... The FC 105/FC 106 (SCALE/UNSCALE) are avaliable in TIA for S7-300/S7-400/S7-1500 but not for S7-1200.... E.g. FC 105/FC106 could be used for 0 to +10V, -10 to + 10V, 0 to 20 mA, - 20 to +20mA and 4 to 20mA.

Forum how use FC105 block to read PT100 RTD feedback value

 Hi, I want to know how use FC105 block to read PT100 RTD feedback value and store the value as Dword.... i.e. at In i have provided PIWxx which i configured , i am getting values at IN but what should i set for HI_Lim,Lo_Lim,BIPOLAR,Ret_val,OUT, , So that at OUT i get same read value which is input at PIWxx in FC105...... If your sensor is connected to the analog card directly you don't need FC105, just convert the analog value to Real and devide by 10.0.... but if you want to use FC105 you can set

Forum Multiple usage of standard library scale function block fc105

I designed the first output by using the fc105 block and simulated it successfully.... I think this's happening because the SAME block fc105 is getting used twice, for both the outputs.... any easy solution to make use of the same fc105 block twice?... There is no limit to the number of FC105 blocks you can use in a program, and to my knowledge functions do not interfere with each other in runtime.... Please show us the code you are using, I believe there is something we have to locate in your calls of FC105 in your program.

I'm trying to force the BIPOLAR input of FC105 to 0, but i don't know the right syntax for it.... I suggest you create anAlways_OFF bit, either in OB 100 or in OB1, and you can then use this bit to force your Bipolar signal to 0 in FC 105
