Pt expires the time is reset. Tia portal at a glance tia portal more than just an engineering framework innovative simulation tools seamlessly integrated engineering and transparent plant operation work perfectly together in tia portal for more flexibility speed and productivity. The current time value can be queried at the et output. The s7 1200 cpu s also have a battery actually a maintenence free super capacitor powered real time clock with a typical retention time of 20 days and a minimum retention time of 12 days.

The time can be read with 2 functions 1 rd sys t which reads the system time this is utc with no offset for timezone or daylight savings time. When the duration pt expires the et output remains set to the current value until input in changes back to 1. The centerpiece is the simatic profinet stack which has been proven in use for many years. The time value starts at t 0s and ends when the value of duration pt is reached.

To do that we ll convert ltime which is the timers current value to a number of strings hours minutes seconds etc and combine them in to a single string to be displayed on the hmi. Properties general system and clock memory clock memory bits and system memory bits. Question 2 s7 1200 hmi time sync version 1 0 entry id. The signal state at the output q will continue to be 1.

Clock memory by default is deactivated. In this tutorial we ll be looking at displaying a running timer on hmi in a proper format. Wt value i need to enter in ret val ofrd sys t andwr sys t. Tia portal how to display running timer on hmi.
