Manfred Posted April 17, 2012 Report Share Posted April 17, 2012 Hello All Is there a limitation for the length of a Responseframe in the PCOM - ASCII Protokoll, or is it possible f.e. to read 255 Memory Longs ? Thanks Manfred Quote Link to comment Share on other sites More sharing options...
Saragani Posted April 18, 2012 Report Share Posted April 18, 2012 Depends on your PLC model. V2xx and V120 have a buffer size of like 480 bytes. V570/130/350/1210/1040 have a buffer size of like 960 bytes. In ASCII protocol ML consumes 8 chars, meaning, you can probably read something like 100-120 MLs in ASCII protocol on V570 (some chars are also taken on header and footer of the ASCII protocol). GPRS modems reduces the buffer size to like 128-150 bytes. CANBus also reduces the buffer size. Quote Link to comment Share on other sites More sharing options...
