I can't find the way, how to send larm from LOGO! to HMI and display it in Alarm View field. Alarm View can browse only Word type and next step is choise which bit shal trigs alarm. It's possible to do? Regards

You can find two helpful examples for LOGO!-HMI connection withstep-by-step documentationsand example codes in the following two links: http://support.automation.siemens.com/WW/view/en/68585344 http://support.automation.siemens.com/WW/view/en/68585346 When you have other questions don't hesitate to ask. If you already have a programm code, a screenshot ofyour tag table in Step7 Basic and your settings and parameter VM mapping table in LOGO! Soft Comfort could also be helpful. Have a nice weekend.

I made a couple of projects in this configuration and it works OK. The whole time I was trying to figure how to make the alarm display in alarmview window. Is it possible to combine variables in such a way that a digital signal (bool type)in the LOGO! alarmview activate the alarm on the HMI.? I know it is possible to connect a word type tag from LOGO! to alarm tag in HMI and change the value of that tag to higher than zero but it still analog value. I'm trying to use the bool type tag to trig an alarm in alarmview window on HMI. Im sorry for my English, mayby something isn't described correctly. Actually, I need a ready-made solution if someone has done such a connection, and it is possible. Regards Jaro

I think basically the most important question here is how you can use a "bool" type for the tag of the HMI alarm in the alarm view. When you have for example a flag M1 in LOGO!, then in the tag table of the HMI tags you canconfigure a tag with the data type bool and address M0.0 and use it for your HMI project. But for an HMI alarm it is not possible to use directlysuch a bool variable. You have to parametrize in this case a word type for the HMI tag. One case you could test is to use a function block of word data type (f.e. Analog MUX)after your bool tag in the LOGO! program, which outputs an analog value when the bool tag (f.e. I1) is activated (see screenshot in attachment). Then in the HMI program you can seta limit with the value of this analog value for your word type tag, so that this tag can set an alarm. I suggest to try if this proposed solution can solve your case. Additonally when you have morequestions about settings alarmsfor the HMI project, thisfollowing conference may also be interesting for you: SIMATIC WinCC (TIA Portal) I hope the information could help you.

Everything I did and actually works, the problem is that the extended program in the PLC and making alarms on that way consume a large amount of blocks and most of all analog flags that are not available to many. Or maybe there is a possibility to make a variable of word type(f.e. analog mux) and hook into it some combination of what the output will give a different value depending on the status of the inputs S1 and S2 - it's a big difference in the number of blocks of the PLC program - then the interface choose in alarmtags the corresponding bit of the variable and assign the appropriate alarm. I tried this but I do not know what value should be variable in order to decipher the word type it into the appropriate bit. But Your sollution is enaugh for now. I have another question about a solution between LOGO and HMI. Is it possible to make atime schedulein the HMIwhat switches at a variable in LOGOdepending on the current date and time? What variables combine to perform this function. Greatings. JARO

Yes, you can use the two inputs S1 and S2 of the Analog MUX, and depending on the combinations of them you can output four different analog values. Have a look on the four fields of the Analog MUX properties in the screenshot above I send you. JaroKoniu I have another question about a solution between LOGO and HMI. Is it possible to make atime schedulein the HMIwhat switches at a variable in LOGOdepending on the current date and time? What variables combine to perform this function. In order to help you I need some more information What exactly do you want to project with the time shedule in HMI?What variable type in LOGO! are you thninking about to use. You mean"current date and time" of the HMI or LOGO!?
