Hi All,Cx-Supervisor, NJ501-1340, Sysmac Gateway.I have been writing an update for a project and converting to this new controller.It's a pretty big project.Using a combination of Ladder and ST.Using Cx-Supervisor 3.5.I created some new Variables in Studio and made them Publish only.Started to create Points in Supervisor and made them I/O connected to the variables in Studio. No problems everything was connecting and working just fine.Then one of the points would not update. I could change it in the PLC and it would not change On the HMI.I deleted it and recreated it and it did the same thing. (sometimes points in Supervisor just stop working and recreating them fixes it).I then copied the control and pasted the old point into it and it did the same. Then other started to fail. Showing no reaction.I stopped the gateway and restarted, no help, I rebuilt the HMI, nope.The can check the tags in Sysmac gateway and they always change when the PLC changes but not the HMI.I checked the point maintenance in Supervisor and it would not change.I dumped all the affected variable in the PLC and in the HMI and recreated them. Then it got stranger.I could change some on the HMI and it would show in the PLC but not the other way.This is on Bools and UINTS.Stopped CX-server, tried using it with Win8 compatibility. nope.Pulling my hair out now. I should be coding but I'm trying to get the apps to work.Any ideas will be used with thanks.Peter

When we simulate a plc program we have to manually input the changes in input(like magnetic reed switch) For example when a cylinder goes from up to down reed turn OFF and reed down turns ON Is there any program available where we can define such things that will turn on and off during the process automatically.

Yesterday one of the guys on the shop floor had a fatal error on a NX PLC. The error code points to a power interruption during program download. From what I hear it wasn't apparent that there was a power outage (maybe I didn't get the full story?). Regardless there was a fatal error and the only option seems to be to clear all memory. We did this but forgot to power cycle so had to do this a few times before we did more reading. After clearing the fatal error, we realized that all retain variable values were cleared. For this we had to manually input some values back into memory to get the machine going again. Is there a way to store retained values into like a spreadsheet? We had to go back to some screenshots that I had taken to put some of our values back. It's ok but not entirely convenient. I remember you can upload the memory values from a CJ2 PLC and keep it as a .mem file. Then you can just download this again to restore the PLC memory values. I don't think the NX PLC has this? I am also reading up now on the NX PLC backup function. It seems like doing a backup will also store the retain variable values. Maybe this is the only way to backup and restore?

Display PLC Time on HMI and Comparing Entered HMI Time to PLC Time
Link068 posted a topic in CX-Programmer
Good Afternoon, I am wanting to do two things with and ORMON PLC and HMI with CX-Programmer and NB-Designer. 1. I want to display the current time from PLC on HMI with the real time clock. 2. I want to be able to enter a time on the HMI which will be compared to the PLC time and will stop a process when when the entered time is equal to the actual PLC time. If I can have some help with this that would be a great help. Thanks, -
Now I working on omron CP1H PLC, i'm receiving ASCII number from another PLC which is something like this "#3031 #3030 #3030 #3030" which mean 01000000. How to convert the ascii number to real number or bcd without separate them? I know how to convert them which is using HEX but its turn out the number will separate into this 0100 and 0000.

Hey! Is there any possibility to acces the PLC variables in GXWorks from another program? Like I want to read and write the I/O-s or Merkes in the Mitsubishi PLC from another program Could someone help me with this? Thank you!

Hi, I am trying to convert a variable of REAL data type to DWORD. I 've tried using Real_To_Dword function which works fine if the real number is integer but when the real is decimal the function rounds the decimal number to INT first (I ve also read it in the instruction manual so no surprise here). I 've also tried experimenting with the function CopyRealToDWORD but again the outcome was not what I expected. Is there another way to convert decimal real numbers to DWORD without losing the decimal portion?

I have a function that reads ASCII code from a transducer, converts the code into characters and places the characters from the serial buffer into a string. Now, I am trying to convert the value in the string into a 64-bit float number. Any ideas on how to do that on the CCW?

Hello. I'm having difficulties of how to write REAL constant in ST. For example (Gap1 is defined as REAL): Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / +1000.0; RETURNS ERROR ERROR: Conversion cannot convert from Integer Literal to REAL I have also tried 1000.0 If I use: Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / INT_TO_REAL(1000); COMPILES OK My question.. How do I write REAL constant in Structure text? I don't want to use INT_TO_REAL anytime I want to do calculations with constants.. Thanks. BR.

I'm fairly new to Mitsubishi and I am trying to limit the amount of decimal places of a real value down to 3. I am using a FX3U CPU and the only thing I see in the manual is that real values are stored with approximately 7 significant figures. Is there a way to limit the amount of figures after the decimal point to 3 without converting to an int value? Also does restricting the decimal to 3 points on GT works change to PLC value at all?

Copy array element to member of a structure
Famous_Fella posted a topic in NJ Series / Sysmac Studio
Hello, In my ladder program I have 7 different arrays (containing REAL values) all members of a structure and I wish to extract certain values from the arrays and put them on another structure consisting of REAL values (not arrays). Which is the best way to do that ? I tried AryMove command but I get an error "Conversion from REAL to ANY_ELEMENTARY[], ENUM[], STRUCT[] is impossible. To get a better understanding of my structures and arrays here is an example: Struct wheel_data Global variable SWheel of wheel_data rad[1...10] of real, vary[1...10] of real, varx[1...10] of real struct. 2 wheel Global variable Wheel1, .... , wheel10 of wheel rad REAL, vary REAL, varx REAL what I wish to do is to copy Swheel.rad[1] to wheel1.rad, Swheel.vary[1] to wheel1.vary, Swheel.varx[1] to wheel1.varx 2nd structure Swheel.rad[2] to wheel2.rad, Swheel.vary[2] to wheel2.vary, Swheel.varx[2] to wheel2.varx until I fill all 10 wheel structure instances with values Thanks in advance. -
Still learning Sysmac Studio......how do I gain access to System Variables like 'PageIndex" so my PLC can be notified what Page the HMI is on? Also, how can I execute an 'Acknowledge All' from the PLC so I can reset the 'Alarm Viewer Popup' from my PLC? Thanks,

I'm having trouble specifying a memory location using the AT specification for an array in the Global Variable tab. I've tried a number of different ways to do so, and searched around online but haven't been able to find anything about how to do this. All I have to go from is the rather cryptic "AT specifications are specified separately for each variable. Set them for all elements and members of array, structure, and union variables." from page 6-62 of the Software User's Manual (W501). That seems to imply that it can be done somehow, but I am not sure how. Right now I have created array elements as independent variables, and then use a FOR loop with a CASE statement to put the proper variable into the array for use later in the program. This doesn't seem particularly efficient, and I have to imagine there is a better way. Any advice on this is greatly appreciated. Thanks!

I am new at PLC programming, I have tried some ways to convert a text into DINT and I haven't found the right way yet, maybe somebody can help me. I want to convert "Hello" to DINT, for example. I tried converting it on here https://www.branah.com/ascii-converter to decimal and then using it as an input for a ROUND, FLOOR, TRUNC blocks to get a DINT, but when I get the result and use as an input in a DI_R i block the output doesn't match with the first conversion of "Hello". Any tips on how do I get it to work, please? Thanks in advance.

There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks, grubb

Hello all. I posted earlier in the week regarding downloading new code to an Omron PLC, but I think the question was a bit vague. As a follow up, and hopefully to clarify, I have the following query. I have created an upgraded program which will be downloaded by field techs using memory cassettes. The revised area of code is essentially a Function Block which amends service lamp behaviour, and in creating it, I have amended the existing function block and added new Internal variables. Is there any way I can ensure that the new variables don''t over write or move the existing variables in the PLC, because this is what is happening when I download it. HELP!!!!!!!!!
