ni lar Posts: 39 Rating: (0)	Dear All, I used S5Timer and I want to set the time from HMI to PLC. When I set 1-9 is OK. when I set 10,11,12.....,CPU SF become RED. I do not know why? I use DB1.DBW6 to set the time. Thanks. Best Regards, Ni Lar

Best Regards, Ni Lar hello. try to use the read and write clock fuction block from the library function and call the pointer data block ie P#DB1.DBB2 like. regards algudkar

If you are trying to set S5 timer from HMI, you will use one word as setpoint in PLC and same is your tag in HMI. I guess, this is your situation. You can't connect integer tag to Preset of timer. It has diffrent data type - S5time. You must convert int/Dint to S5Time and then connect it to timer. You will find lots standard block on internet. e.g. FC40, FB99 etc.

DBM Posts: 10 Rating: (0)	Hello. If you really want to use s5time then you can do like this and call the word diret in HMI like int. L DB1.DBW 6 L 2#1000000000000 OW SD T 23 the number of zeros gives the time base. The one in example is for seconds. Pay atencion to top limits allowed in timer. A better way is to use the SFB4 (TON) and then call the parameter of time direct in your HMI. The parameter Would be DBxx.PT and for changing the time base do the linear scalling in the HMI for that tag. for example to imput in seconds do a linear scaling of 1(HMI Side) to 1000(PLC Side). There are other ways of doing the same thing but i believe this too are the simple ones. Best Regards

Hello ni lar, To underestand why you got the "SF" on CPU, You should know the "S5 Timer" data type.This data type consists of 16 bit which is divided into 4 decades (4 bits).The first 3 decades are Time value in BCD format and the last decade (Just 2 bits out of 4) set aside for time resolution.For BCD,numbers are limited from 0 to 9.Numbers"A,B,C,D,E,F) in Hex are not acceptable for that data type.(See the attachment for more information). The simplest solution I can propose would be: L MW 100 //an integer from HMI ITD // convert to DINT L L#1000 *D //convert to data type time T MD 104 //converted value CALL "TIM_S5TI" //FC40 IN :=MD104 RET_VAL:=MW102 FC40 can be easily found in the program elements in LAD/STL/FBD editor under "standard library"--> "IEC function blocks".
