  1. Dear Forum, I am working on a set of "drivers" for some VFDs and wondering about you guys experience with it. The system layout is as following: FX5UC RS-485: MODBUS-RTU RS-485, lets say with 1x Mitsubishi F840, could be other drives (one drive per FX5UC) Ethernetport: Connected to GT2510, using Freqrol driver Another setup is for some other reasons not possible. I want to have one PLC program for different connected VFDs, scheduled VFDs at the moment are: Mitsubishi F-840, ABB ACS880, Toshiba L.V. VFD, Toshiba T-300MVi.   What I want to do: Read & Write status information - done. Read monitoring values - done. I want to setup some VFD parameters via the HMI. Send the parameter to the PLC and from the PLC to the VFD. The parameters are "basic VFD parameters", every VFD should have, such as: Torque boost, accel/decel time, min/max frequency, base voltage/frequency, etc. Of course these parameters are not simple Pr.0 to Pr. 125 but spread all over the place. I want to check for min. and max. limits inside the PLC before transmitting the data to the VFD. Knowing "basic parameters" will turn out quickly to "VFD specific parameters", I want to be prepared on the programming side. The APSRW for read/write parameters are called through the program and hand shakes with other APSRW calls.   What would be a good approach do to the above?  I rather invest more time into the PLC programming rather complicated HMI-Handling. Reading simple 125 words and the next 125 words, then writing 125word and again the next 125 words? Reading / writing individual parameters? Reading / writing 125 parameters at once? Any other approach for implementation?   Best regards, MarkusR  
  2. StartApp Intouch Wonderware

    Dears,  I would appreciate your help on the below matter.  I am trying to send email using intouch scada.  I am using the following command: StartApp "powershell.exe " + par0 + par1 + par2 + par3 + par4 + par5 + par6 + par7 + par8 + par9; par0 --> is the powershell script path par1 --> is the email par2 to par9 are some parameters i would like to send. I checked the power shell script and its working just fine, but when i run the script through intouch it seems that executes a part of the string.  For example: par0 = "PATH_ON_MY_PC/powershell.ps"; par1 = "test@test.com" par2 = " -par1 12"; par3 = " -par2 10"; par4 = " -par3 test"; ... par9 = " -par9 9";   I am only getting first parameter and if i change to this: StartApp "powershell.exe " + par0 + par1 + par3 + par2 + par4 + par5 + par6 + par7 + par8 + par9; I will only get third parameter.  How can I overcome this limitation?
  3. I have an analog output card 1734-OE2V and there is in the fault/actions page parameters for program mode. What is program mode and when it is activated? Fault mode is clear but... Program should be written the value, but when this happens?
  4. 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.
  5. Hi, My Powerflex 525 Drive is currently working in the Project. I wanted to observe the drive parameters when the drive is running and live with PLC. I usually do that by getting online with the PLC (1756L72S) from RSLogix5000 and then by going in to the Drive Properties from the I/O Configuration folder i use to click on Drive tab and from there i was able to observe all the Drive parameters with the real-time values on which drive is running. Now when i try to observe the Same real time parameters on my other PF525 drive, i follow the same procedure as mentioned above till going into the Drive properties and when i try to click on drive tab its gives me a Screen with a message "AUTOMATIC CONNECTION FAILED". The status of drive in the drive properties still shows me that the drive is running. How can i observe the Real-time Parameters for this other PF525 Drive? Thanks.    
  6. Hi, I'm trying to use a parameter pass a literal string (eg. "Tank Temperature") in a global object, but when it displays in the pop-up I'm passing it to, it shows up as all caps (eg. "TANK TEMPERATURE"). How do I fix this?  Thanks in advance PS. It's not showing up with quotation marks, I used the alt0160 to replace the spaces.  Is there something similar to fix the capitalization?
  7. I believe I have found a bug in FactoryTalk View ME version 8.10. I have a trend object that uses parameter file placeholders on the connections tab. These are direct-addressed to the shortcut ie {[PLC]...}. The historical data from the datalog does not show. (The pens write lines, but when I navigate away from the screen and come back, the lines are gone and begin drawing again from the right side.) The current data does show. This tells me that the placeholders are correct syntax. When the screen loads, the placeholders are being replaced by a string which yields a correct tag path, or else the pens would not be writing correct data. When I replace the placeholders manually and directly address the tag, the historical data does show correctly. This tells me that the datalog is set up correctly and is logging data. I have verified that a previous project of mine, using I believe version 6.0, successfully used this method of using one screen and one trend to plot various tags using parameter placeholders, and the historical data did show correctly.
  8. I am adding a remote device to an existing cc-link network. The master station is an A1SJ61BT11 and the CPU is A2USHCPU-S1. The CC-Link network currently has 20 remote I/O stations and I am adding a remote device. The A1SJ61BT11 has parameters written to its internal memory. In order to add my new remote device, I think I need to only change two parameters: First, I need to change parameter address H1 from 20 to 21 since my device will be the 21st. Second, I need to change station information parameter address H34 from 277 to 4373 to enter it as remote device. I looked at the example in IB(NA)-66721-J(0310)MEE, section 6.3. In the example, they are setting up the parameters for the first time. However, I am only changing two of the parameters. I followed the example except I only entered rungs to change the parameters for H1 and H34. My question: If I run the parameter setting program to only enter parameters for H1 and H34, will it affect the other parameters the original programmer entered? Could they go back to default? Any advice? Thanks in advance
  9. 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.
  10. 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.
  11. Hi friends, Can anybody tell me when to use a local-Static variable and when to use a Local Temp variable whilst creating a Function-Block in S7 -1500 using TIA portal. Thanks for looking in. Best wishes.
