  1. ~4 Line LED display over ethernet/ip recommendations

    Yes , it's one of the negative points of Allen Bradley. I use a Prosoft gateway to communicate with Modbus, but it is an ugly solution. For me it's a great disadvantage of Allen Bradley. The posibility to communicate with open standards it's basic in my opinion.
  2. Tracking the master clock

    In my opinion the control network must be completely isolated from the IT network, and even from the Internet, if possible. The potential risks are enormous , not only economics, but, also for safety of the workers and even outside the factorys. The connection between both worlds must be minimal and the risks must be measured carefully. In a lot of cases there is no real need to have the control network exposed to those unnecesary risks, and someone must says to the CEO that view the factory on real time from his smartphone it's very cool on the work meetings...but in a number of cases, it's not more than a toy, a very, very risky toy.  Cheers
  3. Tracking the master clock

    Some ideas: - If you use a managed switch you could create a VLAN where only the PLC and the desired driver can comunicate: very easy. - Or if you add a firewall, or a cheap PC acting like a firewall (like a raspberry Pi) you could filter the IP's and/or MAC addresses to allow traffic only between the PLC and the desired drives. Not so easy, but same result as above. Cheers
  4. But its much easier and the result much more elegant if you customize the PlantPAx objects to embed the info.  You can add global parameters to those global objects to include the desired information. Cheers
  5. Export data to excel or pdf

    Hi, You can acces the recorded data on the USB or local memory with SMB network sharing: type \\PANELVIEW_NAME or \\PANELVIEW_IP  on a computer on the same subnet network. Then use RSView Enterprise File Viewer (Utility to Read and Save Logs) to save the data as csv and you can import on excel. You can write some Visual basic code to import automatically with task scheduler on windows (or Libreoffice + cron on Linux'es). Cheers
  6. FTVSE parameter file question

    Hi, In FTV SiteEdition you  don't need a parameters file. Create a global object, let's call it "BUTTON" in which you define a main global object paramater, say #1 (but you can add many global object parameters as much as you need/want). On this global object you insert a button to call the desired display (for example a PID faceplate (default one or custom)). On this button you configure that the button pass the global object parameters to the called display (continuing with the example, the PID faceplate). Insert this global object on the parent display. On the Global Object Parameter Definitions tab insert the desired value for #1 (for example"01"). You design the faceplate using the #1 as a replaceable value so when the faceplate is called from a "button" global object , the faceplate will use the global object parameter passed from "button" . For example, in a numeric display of the faceplate you can use the "PIDE_#1.PV" . If you assign to the PIDE controller on the PLC program the name "PID_01", the faceplate will display the Process Value of the  "PIDE_01". I'm writing from memory, and there is more than one year that I don't code on FTV. In 8 hours I'll be on my job desktop and I can explain better, and/or with some screenshots. Cheers  
  7. It's normal, those systems have thousands of options, and when you learn one of them , your mind get's used to this way to work and change to a completely way of work it's , sometimes, harder than start from zero. I have experience with Allen Bradley / Rockwell, and a lot of work made on Honeywell Experion from releases R230 (S9000...) until today (R4xx), but zero experience with Emerson and nearly zero with siemens (a bit with old S5 and S7's, but it's almost forgotten). Cheers!
  8. Hi, I suppose the differents options are selected in the "Goto Display button"s. Double click or right click--> Properties.  In the main tab "General" , on the center there are the  "Display settings" : I think that your "Goto Display buttons" are calling a "Display" plus a "Parameter file:", and both are configured in this config tab. Usually, the display faceplate it's a mere container of a faceplate global object, and usually, this global object uses the parameters contained on the "Parameter file:" attribute.  Right click the global object--> "Global object Parameter definitions" to view the definitions. Inside the global object those definitions are used to control the global object. I hope have explained reasonably well. Cheers
