multiple S7-1200 communication ?

I wrote TSEND_C in first plc Main blockand then wrote TRCV_C in second plc Main block, right clicked one of the communication blocks and did parametrisation trough properties tab. It worked just fine. Then I added TSEND_C on second Main [second plc] and TRCV_C on first Main .. wanting to get some data back from second plc.. parametrised as before. Now my step 7 basic crashes when i try to compile second plc .. if i parametrise parameters of second plc comm blocs .. then step 7 basic crashes when compiling first plc code.. and that goes in circles.. It always crashes while compiling TRCV_C_DB .. Have anyone done multiple plc communications and how ? pls .. leave my question on this forum cause it is specific to S7 1200 .. if you have no answer i dont care .. just pls leave it here .. thank you. regards to experts

kosta Posts: 50 Rating: (4)	Ifound out why i had mess in compiling my project.. i tried to explain it in one tip i posted.. When placing TSEND_C from instruction tree into program tia portal makes TSEND_C_1 if TSEND_C already exists. In program that block is still named TSEND_C and its hard to figure out why TSEND_C_DB dont fit your TSEND_C anymore .. It would be better if tia just kept TSEND_C i had in project and placed it into network. regards
