Then create a TCP Connection and send the value to PC with TCP interface. How can you read out the date and time with SFC1 (READ_CLK) and input them with SFC0 (SET_CLK)?

gre_m Posts: 947 Rating: (45)	Thank you. such a way known to me. I would not want to write the prоgramm (task) of communication to the CPU. I also do not want to use Prodave. But the PG can read data from the CPU. I would also like this makes PG.

(Fetch and Write on a specific IP and ports). And then the parther makes the 'other things'. You have a specific DB where you make a order list with advanced determinated signals...
