  1. software information

    I have a slightly different problem. I am migrating a project from SLC500 to Compact Logix. I have used the  RSLogix Project Migrator  that did a fair job with the logic, however what I need is a tool, or product that will read all of the 'values' from the SLC. The OEM wrote a generic program for the mixers the PLC runs and they have 'configuration' registers to change the operation of the software. For example, N22:16 may be a configuration for a motor. If N22:16 = 0, the motor is single speed, if N22:16 = 1, the motor is two speed, and if N22:16 = 3, The motor has an inverter controlling it. The only way I have found to transfer the values is to manually go through a printout of the downloaded SLC program and manually enter them into the Compact Logix controller. Surly, there is some tool to suck all the values from the SLC???

      I agree that the size of the array may be the cause. My Lane_Control array has 145,600 members. If I start SS without the Lane_Control array tab and add it after I am online, populating the watch table takes a couple of minutes. In this case, I was online and made a program change using Instance 1 of SS. When I synchronized Instance 2 of SS, the program locked up. I could not do anything with Instance 2 except kill it with the task manager. This has happened a total of three times in the last couple of weeks. I consider it a major BUG that needs to be fixed.

    On the second instance of SS V1.18 running on the same computer, after synchronizing a project, the 'Initializing the Table Watch Window' message came up. It has been there for 3 hours. I had to End the task with the Task Manager. Backing up Variables sometimes takes 30+ minutes. Still need to fix the keyboard handling routine so text can be entered faster while online.

    Andy_P, Not exactly what you are asking for, but; Create a Union (Mine is called DWord_Bit) Member 1 = DWD - Base Type = DWORD Member 2 = Bit = Base Type = Array[0..31] Of BOOL Then when you create a variable myVar1, use Data Type DWord_Bit For Dword operations 'myVar1.DWD' := DWORD#16#123F; For bit operations 'myVar1.Bit[1] := True;

    It is good to know that it has been fixed. I am running 1.16. I had problems with the web update function before and had to get an ISO file from tech support. I will see if that issue has been fixed.

    I disagree with the retained variables. I have never set the checkbox to clear present values. I have an array called Lane_Control[1..624,1..25] the data type is a structure with 11 members. It very often is cleared when I make vast off-line changes. It seems to happen when I add or remove a fair number of Global Variables. It may not be illegal code, but the SHL instruction does not work. An instruction that does not work should be illegal.

    This SHL instruction error (nothing on the output) should cause a compiler error:       Also, When doing a program synchronize, most times the variables are not cleared, sometimes they are. The software should warn the user if the variables will be cleared, and offer an opportunity to back them up before they are lost.

    I have 1.16. I am rather hesitant to update in the middle of a project. Can two versions exist on the same computer?

    One thing I would think may be very helpful would be to have the ability to backup the variables and memory from a live PLC and restore them to a program running in the simulator. Studio startup up time (for the programming software) really, really needs to be improved!!!

    Improve Keypress handling. If there are two instances of Sysmac Studio open on a mid power PC, keypress actions are often missed unless the key is held down for a longer than normal period of time.

    The Windows keys do not work on a Unix terminal, however, the Unix keys have worked in every Windows application I have ever tried to use them in.

    From the beginning of time (computer time) a keyboard shortcut for copy has been Ctrl + INSERT, a shortcut for paste has been Shift + INSERT. When working in the Variable Table, Shift + INSERT not only pastes the content in the clipboard, it also inserts a blank variable field. THIS IS WRONG. Please, Omron, fix this!
  13. NJ Devicenet To Fanuc Robot

    Hi Michael, Yes, I did not mean 'force'. I created the tag Y3400_00 and set it to %3400.00 using the AT assignment. I tried to set the bit true using the Watch Window, and I also put the tag as a coil in a line of logic. Both are unsuccessful. When using the watch window, the true button is highlighted, but the online value stays at 0. When used as an output in a line of logic, the logic leading up to the coil is highlighted, but the coil itself remains un-highlighted. (like when you have duplicated outputs in an older controller when some other logic turns off a coil that the logic says should be 'on'). I also tried setting a whole word as Y3400 and set it to %3400 using the AT assignment. No luck that way either.

    I am working on  a project that uses an NJ501-1320 with a CJ1W-DRM21 (sw version 2.1). I have the devicenet working with some DRT2 I/O modules, some SMC valve blocks and two Fanuc robots. The DRM21 seems to be happy with the network settings and sees all of the slaves that are connected. My question is how to format the data to communicate with the robots themselves. Robot 1 has 10 bytes in and 40 bytes out (as seen by the PLC) but I can not force a bit and detect it in the robot. I have tried using tag name Y3400_00 (BOOL) and %3400.00 (Network) Output, I have tried Y3400 (Word) and %3400 (Network) Output. The IO assigned to Node 40 (robot 1) is bank 2, 3400.00 - 3419.08. Has anyone figured out how to do this?

    A new one for today: The project I am working on involves taking three CJ PLC projects and combining them into One NJ PLC project. While working, I have one or two instances of CX-P open, and one instance of SS open. It does not always happen and I can not seem to find the exact reason or circumstances that cause this to occur, but, at times, when I leave the SS window and do something in CX-P, upon returning to SS, some of the keys and sometimes the mouse pointer do not work properly.  The keys I have noticed are 'i, I' to insert an instruction in a ladder rung, 'n, N' when working on structured text (try to type 'END_IF' without an N), and the mouse pointer when trying to select a ladder contact. The mouse pointer will select the variable name or the comment, not the whole element. The only way I have found to make these work again is to click multiple times on multiple objects within the editing window until the mouse pointer actually selects a logic element. At that point, all of the keys work again.  I do not know how one could even program this if that was the desired behavior.
