  1. I am building a redundant system using S7-1515R-2 CPU with TIA V16 version. Creating the hardware, there is not possible to insert any other card to the rack. Even power modules (PM) can not be inserted to the rack. How should I make the power feeding to the CPU. Should I use two power modules/devices or only one. How can I insert IO-cards to the system, is the only possibility to use Profinet IM-cards. In this system I am connecting the bus to the ring and using S2.  
  2. monitoring the ethernet/ip bus

    I need to check possibilities to use that. Thanks!
  3. Analog output fault

    I believe I found and answer for this, thanks for me! Module properties page I can set the fault mode 'Go to low clamp'.  And in the Limit Configuration page I can set the Low and High Clamp. So, in my case, when I am using -10V to +10V, there is set the low Clamp to -10V. This is bad in my system, when I am controlling the proportional valve. -10V is maximum to the other direction. I need to use 'Use fault value' => '0'.
  4. Is there any way to monitor ethernet/ip bus, states or faults and to make an alarm to the panel alarmlist. I am using IO-stations (1734-AENTR) and I would like to monitor somehow the system. I feel that reading the slot status of the 1734-AENTR device is not enough, because it is not possible to monitor all the cards in a slot. How to get alarm on a screen if I lose any station on the ethernet/ip bus?
  5. Analog output fault

    I have an analog output card 1734-OE2V. As a default, there is selected fault mode as 'Go to Low Clamp'. I am using output range -10V to 10V. What is the value for Low Clamp. Is it 0V or -10V? If I want it to be 0, do I need to select 'use fault value' and set the fault value to '0'.
  6. Stratix 5700 parameters problems

    Problem solved. Stratix is using STP, Spanning three protocol. This protocol is checking the loops on the network and during this check it will block all the ports in the switch. I have been setting the smartports then enabling the PortFast Trunk. This setting in the STP page will not block the ports, although it is setting the switch to fault state for 15 to 20 seconds. Thanks for the hint @BobLfoot and @Ken Moore
  7. Stratix 5700 parameters problems

    I am not able to read those links.
  8. Stratix 5700 parameters problems

    You understand quite well, although I was writing badly.
  9. Stratix 5700 parameters problems

    Maybe I was explaining my problem badly. There are 3 systems, all are included with stratix 5700 switch. In the 1st cell, there is a CPU with Stratix 5700. In the second cell, there is IO-stations, drives, panels and Stratix 5700 switch and those are controlled by the CPU in the 1st cell. In the 3rd cell, there Stratix 5700 and CPU. Connection is made Cell1 <-> Cell2 <-> Cell3, so from the Cell2 I have connection both switches. Now, if I power off the Cell3 and power it on again, after few minutes, all the switches will get fault for maybe 15 seconds and after that all will be normal again. If I connect for example programming device to the switch there is not any problems. Why is it so that connecting switches, it will make this connection fault. This is very bad property for our system and it should not happen. Although we have expensive managed switches, it is happening. I believe, lightly managed switches (Stratix) are not doing this. In our system, powering up the switches with a 5 minutes waiting time is not a problem. Problem is if it will set all the switches to fault state and block the communication with the other cells. If there is a way to avoid this, please tell me.
  10. I do have a problem with Stratix 5700 managed switch. I have a system with 3 Stratix 5700 switches with their own systems. If I switch off the power one of the cabinet (including the Stratix) and put the power on again, after that switches are bloking all the trafic in the system for a few seconds. So, linking the system on will make switch to go fault. This can not be correct. What are the minimum settings that is needed to do for the switches, not to go fault during switching power on. I have made now smartport settings for the switches 'switch for automation' => no progress. Still same.
  11. FTView ME shortcut error when using 2 shortcuts

    I do have the panel 2711P-T12W22D9P, which can be set to PV+7 performance. I will try to set the performance on. ==> No errors anymore! Tomorrow I will see it when downloading to panel.
  12. Is it really not possible to use 2 shortcuts with FTView ME panels. When I try to create the runtime file (.mer), I am getting an error that can not be used 2 shortcuts. Is there any possibilities to make FTView ME connection with 2 different PLC's.
  13. PF527 Bus undervoltage user limit

    Thanks for helping. You gave me good information. Feeding power to the PF527 is coming throught the energy transmission chain, I need to check this cable and the connections. Also connection to the motor too. Motor is used in a conveyor, there is quit fast ramp 'running speed during 1 sec'. I have not seen any problems with that before, I think this is still fine. Undervoltage limit seems to be 65%, I think this is fine. I have not changed that, it is in a default value.
  14. I had axis fault, which stopped the PF527. Only way to go on was to switch power off and on again. Checking the faults&alarms, I find out that the reason was Bus Undervoltage user limit. This made 'Immediate Stop' for the PF527. Looking at the parameters, I can not find any parameter for this. In the manual it is said 'DC Bus voltage level is below user defined limit given by Bus Undervoltage User Limit, or device defined limit if the user limit attribute is not supported.' What does it mean?  Is there parameter for this limit? Checking the AXIS_CIP_DRIVE tag parameters, DCBusVoltage is not showing anything, why is that? => Reason found, not marked in 'Axis properties' Cyclic Parameters page
  15. PF527 opto digital output

    This is clear now, I had a wrong connection. I did not have 'sinking' connection. Thanks for helping!
