Hello,

I want to add an auto run function to my PLC 1200. operator need to enter date and time periodically  in HMI (TP1500 comfort ) and they want to ran a part of the machine at that time automatically.

for example 12/20/19  and 8:00:00 am.

Could you please help me how can  I define I/O field in HMI and compare it with local time in the PLC?

Thank you

1. DTL is a structure. You can bind fields (YEAR, MONTH, etc.) to individual I / O fields.

2. Determine the current PLC time using the instructions RD_LOC_T or RD_SYS_T.

3. You compare two times using the comparison instruction.

Thank you so much. This problem solved [snip]
