Content | Communication via System Function Blocks 6.4 Using the System Function Blocks with the RK 512 Computer Connection Point-to-point connection CP 441 Installation and Parameter Assignment 6-20 Manual, 10/2005, A5E00405449-01 Please note that the length of the data that can be transferred is limited to 450 bytes depending on the CPU of the communication partner. Note also that the parameter limits of the RK 512 protocol at the partner only allow you to access data blocks 1 through 255 and to specify as the offset a maximum of 255. Note If you send data to a CP 441 by means of an S5 CP or a third-party device, in this mode you must specify DB as the destination data block with the corresponding number and start address (offset) in the request block. Interprocessor communication flags are not evaluated. The connection via which the data is forwarded from the CP 441 to the S7 CPU is selected by means of the CPU number. The length of the transferable data is 450 bytes. At the CP 441 Communication Partner The CP 441 of the communication partner recognizes from the data type DB in the RK 512 message frame header the type of data transmission you have selected. No programming is necessary in the S7 user program of the CPU. Example Table 6-14 Example of Calling SFB12 (BSEND) using RK 512: STL L 50 T DB60.DBW806 Length = 50 bytes L B#16#1 T DB60.DBB820 Data type DB L 0 T DB60.DBB821 Not relevant L 20 T DB60.DBB822 Starting at data word 20 (offset) L 71 T DB60.DBB823 DB No. 71 CALL SFB 12, DB62 REQ :=DB60.DBX812.0 R :=DB60.DBX812.1 ID :=W#16#1000 R_ID :=DB60.DBD820 DONE :=DB60.DBX812.2 ERROR :=DB60.DBX812.3 STATUS :=DB60.DBW802 SD_1 :=p#DB10.DBX5.0 WORD 1 LEN :=DB60.DBW806 Following a rising edge at the REQ parameter, the data for a length of 50 bytes starting at data byte 5 in DB 10 is sent to the communication partner. The partner stores the data in DB 71, starting at data word 20. The destination information in the R_ID is accepted once during CPU startup and cannot subsequently be changed. |
