  1. 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.
  2. connecting ixt4a to a cj1m/cp1l/ns network

    hi everybody i have a network with 2 pieces cj1m and 2 pieces cp1l communicating with a ns15 monitor. everything is fine. i need to connect an ixt4a monitor in that network. my question is : do i have to make new routing tables or it is not neccessary? my routing table for cj1m and cp1l cpus are attached. if then i have to make new routing table so that the cj1m will be able to communicate ixt4a monitor, how am i going to do it for both monitors? Any help will be mostly valuable and appreciated. thanks
  3. 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
  4. Submitting with an SLC

    Hello, At the plant I work at there are devices with IP addresses starting with 192.168.0, 192,168.1, and 193.168.2 The SLC in question is on 192.168.2 We would like to access it from our laptops which are on 192.168.0 The laptops have their subnet mask set to 255.255.252.0 and we are able to pull see other controllers on the 192.168.2 network. However, for some reason we can't with this one, not even when I'm plugged directly into the Ethernet port on the controller unless we change our IP address to one on 192.168.2 I believe the subnet mask on the controller isn't set right. Can anyone tell what I'm missing here? Here's an overview of the current settings: Laptop: 192.168.0.20, 255.255.252.0 Controller: 192.168.2.17, 255.255.252.0 Any help would be greatly appreciated.

  5. For some reason, some of the symbol names and comments in my symbol table in my project have disappeared. They are present in a previous version of my project. I would like to copy the symbol table from the old project version into the new project version. Can I do this by simply copying a few files from the old project folder into the new project folder? Which ones?
  6. I have a list of 100 faults for my machine. Each fault has an integer variable in the symbol table, containing an integer that matches its position in the list. Say I then want to add a fault in at position 12, I would then have to renumber all the following faults. Is there a built in way to do this automatically? Alternatively, if you have any other suggestions for achieving a similar thing, I would love hear them.
  7. I have had a GE 90-30 CPU331 in my house for 17 years with no trouble at all. I have a problem that I have never seen before. I was editing the program using LM90. I don't know what I could have done in the program to disable an output. Just 1. All the rest of the points in that group on that card still work. I swapped cards with no difference. All of the elements of the rung are true (highlighted). The output is not on or highlighted. The nickname over the output has ONE letter highlighted. The bit in the reference is "0" and is highlighted or "grayed out" (the cursor is not on it). I searched for coil conflicts. I am using this output contact lots of places but only one output. The logic is working correctly when I use another output or %M. This is an isolated output which needs to be in this group (moving it would be awkward). What does a "grayed out" reference bit mean?
