Hello! Need some help, please... I try use function GetPlcDateTime(); It work good on S7-300, S7-400, Sinumerik 840D, but on S7-1200 I get an error: "CLI : invalid CPU answer". Maybe any peculiarities?

Hey Dmitry,

the message tells you that a client cannot access either due to "protocol not enabled" or DB optimized.

Are your configs correct?

What I can't interpret if this is even supported on S1200... but I can't test it myself at the moment :(

  Yes, config is correct: full access enable, PUT/GET enable, optimized block disabled =(

f.b. is right.
GetPlcDateTime() and other functions are not implemented in S7Protokol of S71200/1500.
