  1. Simon, That is really great information to know. I would not have expected it to affect scan time to that degree. As you pointed out, most projects don't require a super fast scan time, so I hardly ever notice. Thanks for the info! Damian
  2. I have a sampling of Unitronics hardware that I keep on hand for aid in demoing and development. I tried to remove a V200-18-E3XB from the back of my V570 and snap it into my V1040 and to my suprise ................ it doesn't fit. I had another V200-18-E3XB that I keep on hand as spare. That does fit. Upon inspection, I found the following. 1) The PC board of the original snap in module has extended corners that interfere with the studs of the V1040. 2) The PC board of the newer IO module has those corners removed. 3) The plastic studs on the V1040 are much longer than those on the V570 Why are the studs on the V1040 so much longer? The reason I ask is I want to know if it was intentional for some kind of hardware incompatibility. I want to know if I can cut the corners off my old module so that I can still continue to use it as a demo with the V1040. D
  3. Hi Dan, I use an extended laptop often, so I run into the same problem. Here is the trick When it happens ............. Hold down "ALT" and then hit the space bar. You won't be able to see it, but the popped up window will actually display the default windows drop down list for that window. Then type "m" to select MOVE. Now, just use the arrow key (Left arrow if you were extended to the right) to move the windows back into your range of view. You can practice it with a window that is in view first so that you can see what is going on. D
  4. Hi Emil, In my case I need to develop a universal multizone (up to 16 zones) temperature controller which will utlize the same program for many different machines and process's. If it would have been variable, I could have assigned it an MI for all 16 zones, and simply changed the value in the configuration database to set the number of stages. Now, If I choose to have the number of stages variable, I have to declare 48 different Auto Tune blocks with with a bunch of comparators to achieve the same thing. This coupled with the fact that I can not set through the program the type of thermocouple used makes what could have otherwise been a very solid universal program a lot messier. PLEASE Unitronics, do not try to protect us from ourselves. This is automation, not kids toys.
  5. Why wasn't the number of stages allowed to be assigned a variable?
  6. I really must be missing something here! F=PxA Our P = 5 pounds / in^2 Our area A (touch screen cutout of V1210) is 11.69in x 8.9in = 104 in^2 so F = 5 pounds/in^2 * 104 in^2 = 520lbs the V1040 works out to almost 500lbs itself That is 520lbs of linear force trying to push the HMI out the front door of the cabinet. That is like 2 and a half full grown men standing on the back of the HMI. Where am I going wrong?
  7. I am having a hard time finding the published update rate for Unican. Seems like I saw somewhere (perhaps a power point demonstration) that it can update all the nodes within one scan of the PLCs. Specifically, I am interested in how fast a V1040 / EX-RC1 combination will update.
  8. Based on the cutouts for each device, you are looking at roughly 105in^2*5psi = 525lbs for the 1210 and 98in^2*5psi = 490lbs for the 1040. That's a pretty decent amount of force. Unless you are putting entirely inside enclosure.
  9. Hi Emil, The ASCII to NUM function will only work with BYTE packed characters, which is my original complaint. I'm not sure where you are going with #2. But to me the underlying point is that I don't want to have to write code to separate them out (or compact them), and that I can think of several reasons why I might not want more than one ascii value compressed into the same operand. The Procol Copy Buffer function for example allows me to copy ASCII input as byte packed or integer packed. If I choose Integer packed, it renders the ASCII to NUM function useless. Viewing the values in the operand in HEX is a good suggestion, and that is the way I normally do. Thanks, D
  10. Hi Emil, Can you please point me to where in the standard this is supposed to be? RS232/485 as far as I know is an electrical standard that does not dictate any protocol. I think you are maybe thinking of Modbus Ascii, in which case your above statement rings true. You have given me the freedom, using the Protocol function blocks, to accomodate non-standard protocols. Making it so that I can't select different combinations of communication parameters takes some of that freedom away. Thanks, D
  11. We need an option to to perform an ASCII to NUM operation on a Integer basis. Right now, If I have the ASCII values stored in contiguous integers, I have to jump through hoops to make the conversion. It is nice to store the ascii values separately in the integers so you can look at those integers and see what is in there without it be combined as a double byte. Or ........ as a plan B, allow me to "view" the MIs in BYTE mode using the format column of the operand window.
  12. For some reason, the CommInit Function block will not allow me to select Parity as "None" with 7 Data Bits. Why not? I can with hyperterminal. And the device I am trying to talk to is set up with these settings. If you try and select NONE, it just ignores you and puts back in EVEN parity. I found this after a couple hours of scratching my head, because I assumed that it was actually using the settings I selected. If you try to out smart it, and select 8 data bits first, then no parity, and then go back and change the data bits back to seven, it immediately stuffs an even back in the Parity. Can this be fixed?
  13. Hi Simon, One other trick to measure the scan time is to use the Interval function backards. If you Put the Interval End function in a subroutine that is scanned once every PLC update, and the Interval Start function just after that, it will include the entire scan time. If you want it to exclude the time spent executing ladder code, just put the End in the very first network, and the Start as the very last block executed. Have you come up with any numbers regarding the speed of the V570 VS the V1040/V1210? I am curcious if the V1040 or V1210 might in fact run a bit slower than the V570 just due to having to manage the larger screens. However, I remember having heard it said that the Logic Controller and the HMI controller are two separate chips, so maybe that would leave the PLC scan time identical to the V570. That's assuming of course they used the same chip in all three, which also may or may not be true. D
  14. Ahhh! So your the graphics Guru! You really make some nice looking stuff. I think the guys in R&D should be contracting you to help them with generating the graphics for the next generation. How do you make most of them? Are they just rendered 3D models from some CAD software? I have a V1040 that I keep as a Demo. I can run it on that if you like and take some pics/video. Damian
  15. This is a good question that has popped up several times in the past. If you search the old forum you will find a few suggestions. There was also a user who went by Ober that made some quite nice looking graphics, but I am uncertain if he continues to use the new forum under a different name. As a consequence of being a contract engineer, I typically have to maintain a lot of different HMI softwares to satisfy the standard requirements of my customers. So I tend to mix and match the libraries of all of these softwares as it suits me. There are a handful of these softwares that are free downloads. I wonder if this topic doesn't deserve possibly a separate spot here in the forum. Possibly a community galery so to speak where everyone can share their HMI objects with each other. This could also coincide with maybe descriptions on the best ways to fabricate or convert your own, and what software techniques work the best. Wouldn't be a bad blog topic.
  16. Hi Stein, Any ideas on this yet? Customer is starting to get antsy and I'm running out of excuses. Thanks, Damian
  17. And some more info .............. No matter what object I choose number password numeric range Lists of texts Text Timer Input Counter input The pressed property does not work on any of them. Is there some kind of goofy system bit that can be causing this???
  18. Ok ............ I was also able to find OS 3.4 (B3). No change.
  19. Hi Stein, Thanks for the explanation. D
  20. It was difficult to take a pciture that shows it well. I changed the background to yellow to help make it stand out better. The first pick shows the V570, Remote Operator, and Visilogic all showing the same screen. The second just shows the V570 displaying in "Unpressed" fashion. The Third shows Remote Operator displaying it properly, along with Visi to the right also showing it properly. And ............... The pictures.
  21. Hi Stein, Where do I get my hands on OS3.4(03)? I'm using the most up to date (as far as I know) Visilogic 9.3.0 Build 0. and OS3.4(03) is not an option. "Buttons" are acting normally, you can see the change in state. Specifically, the one that is causing grief is the numeric entry with "pressed" selected. Sure, I can come up with some pictures. Thanks, D
  22. Control Engineering www.controleng.com Automation World www.automationworld.com (never requested this one, it just started showing up one day)
  23. Why don't Draw Axis and Draw Line show up in Remote Operator?
