More tools
Nubitek Free Utils encompasses a set of functions which enrich the S7-200, making it more powerful and easier to use for the programmer. They are ready to be incorporated into STEP7-MicroWIN and behave like any other function of the S7-200.
Nubitek Free Utils consists of 3 libraries which draw together mathematical, text string management and time management utilities.
- Innovative and straightforward clock alarm management.
- Functions either to insert in an SMS or e-mail, or to display on a screen, hour and/or date.
- Mathematical and statistical functions.
- Advanced handling of text strings.
- Scaling of analog signals.

Example
How can I send on Monday mornings an SMS message to production with the status of machines?
Its very simple using the Day_And_Time_ALARM function and the Nubitek_SMS_Manager library:- Segment 1: the call to the Day_And_Time_ALARM function with the parameter "07:15:00 MO" activates the output bit Time_SMS during a second on the set day and hour.
- Segment 2: the call to the Send_SMS function of the Nubitek_SMS_Manager library, using the rising edge of Time_SMS, results in sending the SMS message to the mobile.
