STL statement

[Tom749]

Can you explain this following STL statement in details? (It is so hard for me every time) Thanks for your help in advance. ========================================= L #Address // INT ==> Word T #Temp_Address CALL "DPRD_DAT" // DP Communication Read LADDR :=#Temp_Address RET_VAL:=#RetVal RECORD :=#Recev CALL "DPWR_DAT" // DP Communication Write LADDR :=#Temp_Address RECORD :=#Send RET_VAL:=#RetVal =========================================

See comments above. <F1> is your friend. Don't be afraid to use it. This looks like an example for communicating with a Profibus DP slave with inputs and outputs.
