Can everyone help me?Read / write a larger R parameter block from the PLC.
The function blocks FB2, FB3 (GET/PUT) allow to read/write eight parameters per job. In the example attached (FB88), up to 40 R parameters are transferred via multiple FB2/3 calls.
CALL FB 88 , DB 88 (
Read := E 7.7, // Start read job
Write := E 7.6, // Start write job
Anz := 40, //No. of R parameters
R_Nr := 5, // First R parameter
Unit := B#16#1, // ChannelNo.
Activ := A 5.7, //LED T1
State := MW 200, //StatusWord
Error := A 5.6); //Error in FB2/3
