Dear All I attached a Hart compatible device to PIW512. Value obtained "classic way" is O.K. (MD274 OB1 net 2). HART-value via PIW528 is O.K. (MD110 FB80 net 3). Using SFC58 & SFC59 results after a while in a CPU-stop (cycle time exceeded). Sometimes i receive a value, but not every clock-trigger (M198.7). Where do i go wrong? regards Paul AttachmentHART-reading.pdf (682 Downloads) |

revisedversion attached Using SFC58 & SFC59, sometimes results in avalue (I0.2 = always true = continuous polling). CPU keeps running, probaly due removing loop in FB80 net 4 & 5. any suggestions? AttachmentHART-rev-e.pdf (636 Downloads) |
