Hi, Why do you have such a old IM 151-1AA01, -1AA04 is the actual one, when I look to the CP443-5DX04, thats a real new one. You could look also if the Master is up-to-date: New Firmware V6.1 for CP 443-5 Extended (6GK7 443-5DX04-0XE0)this update can be done by yourself if desired. For the old IM 151-1AA01 where no Firmware updates online possible. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |

Dear Nazareth, as far as I know does the DP Slave, just like all the other DP Slaves available, support the DP Status function. So if the DP Master asks the DP Slave it will send the Master a DP Diagnostics Telegram divided in two parts. J_Bell |

Hi everybody, Meantime I’ve had the same problem with another station, several hours between failures. The IM was replaced. So we built a small Profibus network using a spare CPU, CP and those IM151-1. After couple of hours one IM went down into failure several times and some investigations were performed. We used a scopemeter to check the signals on the backplane bus.A brief sketch and the normal signals patterns are shown in the attachment; we noticed that these signals are visible regardless of Profibus cable connection or electronics I/O modules presence – power supply is all the IM needs to initiate such a communication on the backplane. Well, when the LED pattern shows SF: ‘BBB’, BF: ‘BBbbbbbb’ or 'BBbbbBbb' there was no transition on the data lines (V1=3.1V, V2&V3 were grounded). During the pattern SF: ‘BBB’, BF: It seems these LED patterns shows an internal problem, probably in the ET200S backplane bus, due to a faulty IM151 or I/O module too. Hope to help.
