Richard Webb posted a topic in MitsubishiI have a problem with PLC not seeing the input. I am using a FX3S, however, because I still am using GX Developer, it will only recognise it as a FX1N. My problem is I did a small programme for an alarm on a "Blow Down" system for filter cleaning on Silos. Tested it at home with a cyclic timer, everything working fine. Got the controller this afternoon and found I had a problem. It looks like it's not seeing the input to reset the time out timer. Worked for a while, then fell over. Using X0. The switching time I am monitoring is 20msec, which I thought would not be a problem. This is going to be a major setback for me with this project. Eight of these controllers. Any help would be great.
[HMI Sample Code] - Crimson 3.0 Simple String Validation Pattern Matcher
marv_tech posted a topic in Download CommentsView File Crimson 3.0 Simple String Validation Pattern Matcher I developed this for work and thought I would share. It can be used for input validation and we needed it to enable validation of scanner gun input through the USB port. I also use it for serial input validation. Usage is: pattern.isMatch(input string, input pattern) which will return 1 if match, 0 if not a match I have also included toUpperCase and toLowerCase functions for strings. To use in your project, simply copy the pattern program folder to your project. This can be auto-migrated to crimson 3.1. Pattern string syntax is described in the comments or by clicking the guide button. Worth using this testbed to debug your pattern strings before using in a production environment. The controls and bits on the right side of the test page allow you to tab through your pattern and the string and see what matches each char. You can see a mockup of a real world batch-entry view on the "Demo" page and edit the input fields to try to defeat the validation. If you end up using it, toss a thanks my way if you can. If you find any bugs, please let me know. Built with Crimson 3.0 v707.000, tested in built-in emulator and used on Graphite G07s with both Crimson 3.0 and 3.1 runtimes.

serial input string
firstname.lastname@example.org posted a topic in MitsubishiHi I'm quite new to plc but very new to mitsubishi. I have an input string eg G+002.7 which represents a weight. I wish to take in the input string then move/convert to int omitting first char, On other plc's i have been able to use a modifier like d200 then the no of chars. How do i achieve this in gx works3 Any feedback gratefully recieved Paul
One 4-20mA signal to two analog inputs
MZohaib92 posted a topic in SiemensHi,I want to read transducer signal on PLC.I am using 7kg60008ab/nn transducer and it's analog (4-20mA) output is connected with analog meter.Can I connect the transducer current output (4-20mA) signal to PLC analog input in series with analog meter display???So that I can read the value on PLC simultaneously with analog meter?
Output polarity selection
franciscoazzad posted a topic in Other PLCsHello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2. I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. · When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) · When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) · On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3) Has any of you experienced something similar? Is there a better way to execute my purpose? I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!

Cognex and Compact logix
Nickyv6363 posted a topic in Allen Bradley / Rockwell AutomationHi, I need help finding the length of a string. I am using an In-sight 9000 series camera with a compact logix 5380 and communicating over ethernet. Unfortunately, the string length is not provided in the AOP, and the barcode length will constantly change. I told to use the FSC instruction, but I cannot get it to work. Thanks

unit of time in D8284
arcp posted a topic in MitsubishiHello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!

paulrd42 posted a topic in Allen Bradley / Rockwell AutomationSorry new to working with PLC's, I am trying to write text to a ST file on an RSLOGIX 500 machine, its for a LED display, I am just trying to update the screen to new texts, it all works I am just having trouble inputting the text properly into the string file. I would like to read about it if anyone can point me to a good document or manual that can explain what characters to use? I see many posts about using VBA using Excel work on RSLOGIX 500? But would like to know how to do it manually first. Thank you
GetVariable in VB.net on NA
Septimer posted a topic in NJ Series / Sysmac StudioHi all, I am a new user of VB.net on NA Omron HMI, and I need your help to solve a problem. In my case, I have to get a HMI global variable value in VB.net, but the VariableName is in an other variable (string). For example: Var1=4 Var2=6 VarName="Var1" I worked with a "SetVariable" function to modify the value of different variables, but right now I need to read the actual value, in the example values 4 and 6. Do you have any suggestion?
StartApp Intouch Wonderware
lepass7 posted a topic in HMI & SCADADears, 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 = "email@example.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?

1756-IF8H HART Device Diagnostic Codes
GuyMiller posted a topic in Allen Bradley / Rockwell AutomationI currently have a Rosemount 87 series flow meter connected to a 1756-IF8H analog input module.. We are not receiving flow from the device, and the channel is showing a diagnostic code of 009... I can not find a diagnostic code list anywhere explaining what this means, has anyone had any experience with the diagnostic codes for HART Devices?
Q68ADG - Abnormal Analog Input
d4rkm4n posted a topic in MitsubishiHi guys, So I found that CH2 on Q68ADG is abnormal. Whenever I short the termination, the digital value goes max to 4096. Input is set to 4-20mA with normal resolution. I tried to simulate 4mA-20mA but still same result. Does this mean the CH2 is damaged? Equipment at site is normal and give 5mA signal. Thanks!
Omron NJ/NX to AB Ethernet/IP String Data type exchange
Brooksy posted a topic in NJ Series / Sysmac StudioHave been able to exchange data types of BOOL, INT, DINT & REAL between Omron NJ/NX CPU with Allen Bradley Logix CPU's with Ethernet/IP using the CIPUCMMRead & CIPUCMMWrite instructions. I now have a need to exchange "STRING" variable types. Have tried varions string lengths in the NJ without sucsess. AB default string length is 82 & Omron 256 but I think the difference is the length headder that AB has with within their String Tag type. I know I could convert my strings to an array of bytes & sent them this way, but was looking for a solution to sent them as native strings. Hope someone out there has done this & can share their leg work?
1756-IF8 rev 1.5 Input tags freeze
der0492 posted a topic in Allen Bradley / Rockwell AutomationThis is a 1756-IF8 rev 1.5 Analog Input module. This has happened a couple times where the Module Input Data, (not mapped), goes to the high limit and freezes (Data Monitor data is static). Plant operators pointed out the trending wasn't accurate. There is no fault on the module, no yellow triangle on the system tree for the module. The Module properties show no faults, and RUNNING. I have done a "Reset Module" both times, (Module Properties - Module Info tab), while monitoring the module data. As soon as it resets, instantly the Data Monitor starts showing live data. I'm going to try and replace the module at first, but I have some concerns. Has anyone run into this before? I can't seem to find any information on the "Reset Module" animation, and what it actually does. Any information, (or where to look), would be appreciated. I don't like to hot swap, but I believe I will need to in this case, (utility). Will the current properties, e.g. scaling transfer to the new module? Thanks Dave Redman

ASCII String to LREAL number
Arceus posted a topic in Allen Bradley / Rockwell AutomationI 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.

1747-NI8 Open Circuit
murrbuck2 posted a topic in Allen Bradley / Rockwell AutomationI have an 8 point analog input card on a rack with a SLC 5/04 CPU. It has been in operation for 20 years or so. There have been some power problems at site lately and ever since they fixed them I have been having issues with 3 of the 4-20mA circuits on this card showing open circuit. I have had my meter on them when they show open circuit. The signal reads 3.96mA, just below the 4mA minimum and boom, the machine goes down. Is there a way to adjust this tolerance?? I don't think there is anything wrong with the 3 transmitters so the error is just a nuisance.
