  2. Hi All: I am new to Citect and looking for a way to create 1 page that has 25 valves (genie that pops up a super genie) and some analog genie/super genies. What I want to do is create 1 page and dynamically replace everything when someone selects a different rack in the system. I have 4 systems that have the exact same equipment times 10 so I want to avoid creating 40 different pages. Can anyone help with some ideas on how I can accomplish this? Thanks M
  3. I have a FactoryTalk 8 application that exhibits some weird symptoms when I run it. I have buttons whose "visible" state and "enabled" state are based on HMI tags. The states of these buttons don't update. I have screens that fail to close when the "abort" command is issued. I have vba that connects to a tag group, which fails to retrieve the value and produces an error. Some tag values from the PLC (always direct-addressed, I think) show up correctly, even when other symptoms above are happening. These issues randomly go away sometimes after a restart and the entire application runs fine. Does anybody have a clue what could be doing this? (Using Windows 7 Professional 6.1.7601 Service Pack 1 Build 7601, SE version 8.10.00 (CPR 9 SR 7.4), Internet Explorer 11.0.9600.17633)
  4. Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes.
  5. OMRON CJ1M CPU 21

    Hello to all Since a certain time I've noticed that the parameters values sent to the plc via IHM are not anymore recognized by the plc I'm obliged to re-enter other parameter values to see the machine working fine again. The plc reference is: CJ1M CP 21 The IHM reference is NS10 What would be the problem,? Best regards.
  6. CS1G-H CPU42 with CS1W-PRM21 problem

    Hello everybody, I have a problem connecting CS1G-H CPU42 with CS1W-PRM21. Prm21 is inserted in slot 9, and i have previously made connection to prm21. After downloading configuration to prm21 i cant connect to prm21 anymore (connection to plc is working fine). The cx-configurator says CS1W-PRM21 PROFIBUS DP-V1 Master Communication Failure with UnitERH is on (red), BF is flashing red, RUN is on (green), PRM is on (green) and BST is flashing green. How can i restore comunication with the cs1w-prm21 to diagnose the problem? After some examination the problem is (probably) that i have configured prm21 to write in the adresses of CIO3000 to CIO3400. That is interfiering with other address. Is there any way to force the output of the prm21 off, or make device go in offline mode.At the power on of the prm21, i can test the connection via cx-configurator and is working and after 2 seconds the prm21 goes to stop mode and begin writing to address of the sysmac bus area. I am thinking if i can stop prm21 from writing to that area i will be able to connect and load default that any way to stop the prm21 from automatic start? or is there a way to reset prm21 to factory settings? best regards

    Hello, We want to do excel reports on Siemens PLC. We do not want to use historian programs. Do you know another programs?
  8. Copy HMI Tag value to parameter

    Is there any way to copy the value of an HMI tag to a parameter (FactoryTalk View ME 8). I am looking at doing something like: #100 = HMITag1 value I get #100 = HMITag1 name when I try anything meaningful. For example, if I have HMITag1 = test. I want to get #100 to equal "test", but I keep getting #100 is equal to "HMITag1". A little more background in case there is a better way of doing this. I have several components (pieces of equipment) that are the same. Each has its own program on the PLC that includes a group of tags for the component's settings. Most components use the same settings by copying tags from the controller level to the tags at the program level. A couple components need special settings. I have one HMI screen that each component will display for settings. A parameter file for each component will be used to display the settings from the proper Program. The parameter files have a tag for the program name (#100 = Program:ComponentX). On the HMI components I have {::[PLC]#100TestVar1}. This works great when #100 is a program name (the special cases). I was trying to get #100 to equal a blank so the object would access the controller level tag so any changes to the global versions would be across the board. I thought I could create an HMI string tag equal with no value to accomplish this. I just can't get #100 to equal a null string.
  9. Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.
  10. Hi guys, I have a problem with GX IEC Developer 7.04, i hope some of you can help me.

Com_port parameters: FX Parameters: Transfer setup: PLC Type in the program is the same like physical one (FX1s). I try to change all of this stuffs but there is no result. The cable I use for comunnication is this type: Thank you very much in advance. Have a nice day! eng R. Bukov
  11. CPU 314IFM adress

    Hi, I have a CPU 314IFM order number 6ES7 314-5AE10-0AB0 when i select it in hardware config it show I/Q adress 124 -155 while it should be to 129 only (the manual mention that and it covers all inputs and outputs and the special funaction also) I try (offline) to change the order number only (another 314IFM) found it give different address range for each CPU while it all have 20 DI/16DO 4AI and 1AO
  12. Hello all, I'm new to this forum, hope I will be able to get some answers on this forum. I'm wotking on maintanance for machines under productiona and I would like to conect one machine to my work PC. But when I try to setup conection with RSLinx, RSLinx don't see my PLC. Problem is that my PC is on network with IP addresses 192.168.8.XXX and machine is on IP address and between is cisco RV180 routher which is set to have LAN address (company network), and WAN is set as (subnet, gateway, dns When I conect directly 1756 ENBT/A card to my laptop (laptop is set to same range of IP addresses) I can see PLC and everything is working but this way is not practical for me. Is there any way to conect my office PC to PLC, some settings in RSLinx Clasic? Any idea would be helpful. I attached simplified network drawing for easyer understanding. network.pdf Thank you for your time and help, best regards, baric1007

  14. I have been supplied with a list of tags from a vendor containing flags indicating if alarm conditions are on. These tags have the format AlarmGroup.Num.1 through AlarmGroup.Num.10 as recorded. Reading these tags as presented by making a read request to the Read Tag Service fails with general error code status 0x05, "Request path destination unknown. Probably instance number is not present.". I am using ASCII extended symbolic segments to translate the tag into a path so the instance number is not required for this approach. Upon further discussion with the vendor I found out AlarmGroup.Num.1 refers to bit 1 of the AlarmGroup.Num tag that is a DINT tag. I can successfully read the AlarmGroup.Num as a DINT but I was hoping for a more universal solution that would not require me to add solution specific parsing functionality to identify tags that refer to individual bytes from other tags and manually shift the bits as required. I am very new at this and I want to know if it is possible to address an individual bit (for reading only) from a DINT tag and how to build the path to access it. Are there other types of segments other than the ASCII extended segments required?
  15. I am trying to setup communication between an EIP21 and a AB Compactlogix processor. Setup both units with Network configurator and Logix5000. In Logix5000 I used the Generic Ethernet Module with the correct consumer and producer tags and instances. When I go online Logix can see the EIP and bring up the module information but the connection itself is in Error 16#0114 Electronic keying Error. Unfortunately cannot find a way to disable keying like possible on the Controllogix Ethernet module. Can Anyone help. An application example or some tips how to resolve it would be great. Kind Regards Rolf
