  2. Hi everyone! I got this machine with a CP1H PLC and NS8-TV00B-V2 as PT. I was told that they were working fine, but suddenly, It appeared a communication issue: black screen and "connecting..." at right bottom. I dont know if It is a configuration problem or some hardware damage.  These are the configuration in the PT and the PLC. The communication is through RS232 Serial.  I tried to communicate another PT screen with the same communication settings and IT WORKED!. ' I've been thinking that, perhaps, the serial port A is damaged, I have tried to set port b, but I havent could. How can I configurate PORT B??   THANKS...

  5. Dear Experts, I have two M580 remotes I/Os panel and CPU panel and I want to connect all by using BMXNRP0200 Fiber Converter modules. In IO panels the backplane is BME XBP 1200, after the CPS3500 at slot "0" I have installed CRA 312 module and then all other IO modules AMI, AMO, DDI & DDO. My question is: at which slot on the backplane I need to insert BMXNRP0200 in IO panels and at which slot in the CPU panel and how I need to make ethernet and fiber connection on the module. It has two ethernet ports up and down and two fibre ports up and down. Which ethernet port (up or down) I need to use to connect with CRA and which fiber port (up or down) I can use to connect with another BMXNRP0200 Fiber Converter installed in another panel. I have attached the snap of configuration where I have CPU panel and two remote IO panels ?  Best Regards, Ahmed      
  6. PID Control Loop

    You're not vaporizing or condensing on the water side so M*Cp*Delta T can used to calculate the amount of heat being input and removed in the system. The steam side is a little more difficult and only useful if you're trying to evaluate the heat exchanger. M = mass flow rate, #/Hr Cp = Specific heat of the fluid. Water is easy. It's 1 Delta T is obvious Hopefully you have flow measurement. Most of the time (in my industry) liquid flow rate is displayed in GPM (gallons per minute) or BPH (barrels and hour). If GPM it's pretty easy to get #/Hr. #/Hr = GPM * 500 * Sg (specific gravity). Water (in your temperature range) has a specific gravity of 1.0-ish, which makes the calc easy. Know how much heat the exchanger is capable of producing (Bob's warnings about hot spots and calcification are spot on) vs how much heat is required is a good start to analyzing whether or not you can speed the process up and it will tell you if the exchanger is fouled. I doubt if you can. You may even have a fouled heat exchanger if it's been in service for a while and the steam system water isn't treated properly. There should be an exchanger spec sheet available. Sometimes (rarely these days) the nameplate has the info that you need. Sensor 1 is your PV since you're are blending cold water with hot water and the desired temperature of the blend is your target.
  7. L Series CPU Program Transfer

    hi, here are some thoughts: - you can read and later only download the parameter of the simple motion module without affecting   the parameters of the other intelligent function modules, therefore inside the read from plc dialog   deselect all checkboxes except for the parameter of the simple motion module. Then use the 'detail'   button on the right side to select which parameters from the simple motion module should be read or written - attention: only WRITE the Simple Motion Module Parameters if you use a (second) simple motion module.   If you only replace the cpu-module (connecting the new cpu module to the 'old' simple motion module) you   should NOT WRITE the simple motion module parameters! If you use a second simple module and write   the parameter also be sure to select the 'write to ROM' setting inside the 'details' setting, otherwise the   parameters will be lost after power off.   - you can use the 'MR Configurator' Application to get further information about the error from the   simple motion module. Also you can check if the simple motion module is properly setup.   if you have the servo settings (*.mr file) you can open it inside the mr configurator application.      
  8. PID Control Loop

    OK putting on my "Engineer's Hat" for a moment let me make some observations. 1. Assuming that Water Flow and Pressure through the HE is constant then the Delta-T you can achieve between Input and Output of the HE is going to depend on the setting of the proportional valve. 2. If you can codify the formula so that the Exit temp of the HE is between 80 and 85 then you'll heat the tank at it's fastest reasonable rate.  I say this because going over 85 you risk hot spots in the HE and calcification of the coils or plate/frame assembly.   3.  One other thing to consider on this scenario is your inflow and outflow rate of the tank.  You might improve the process by bringing the tank to 65 and once you start cleaning add cold water immediately, knowning the HE can being it up to temp as it is only a portion of what's coming out. Just some observations.
  9. PID Control Loop

    Hello All, I have a question about heating a tank of water. Its not really Allen Bradley specific, but i am using a ControlLogix unit... Anyway, I'll attach a basic drawing of the layout. I need to heat water to 65deg using an existing heat exchange. Once it is hot, then the water is diverted to a machine for cleaning.  At the moment i am using temp sensor 1 to continue the cycle until it reaches temperature.  Meanwhile Temp sensor 2 has three levels (x<80, 80<x<85, x>85) to open the proportional valve to regulate the steam to the heat exchange at three levels. This process takes a long time, so I'm wondering if i could improve the process anywhere? Besides hardware changes.  Thankyou. Edit: Because of the layout of the sensors etc. The water at sensor 2 reaches temperature much quicker. I was using sensor 1 to ensure the entire tank was hot enough. Maybe i just need to do some trials with sensor 2 as the process variable.
  10. Hi all:   Hope somebody will help me with the below error encounter on the NA. I mapped a external device (NJ PLC) variable (which is a structure) to a NA Global variable and the structure is automatically created in the NA data type as expected. I then create a new NA global variable and defined its data type as the auto created structure. However i observe the created new NA global variable is highlighted with an error "a data type cannot be used by both mapped and unmapped variable ....." ( pls refer to the attached screen).  I have found and view on the Youtube this video :"Introduction To The NA DataTypes" (link: https://www.youtube.com/watch?v=VZxWnVn1CSY). that clearly show the "imported" structure can be used for unmapped NA global variable even there is some variable already mapped to external device variable (starting from the 3:50minutes mark of the video). In my NA program i would need to create such unmapped variable for my logic use. Also i observe that i was unable to delete the auto created structure from the NA Data Types even after i deleted all variables that are defined with that specific structure. How can i delete such auto created structure in case i want to clear off some of those unused data types. I am using Sysmac Studio version 1.30.0.17. The HMI Device created is the NA5-9W00 (version 1.11)          
  11. Take a look at DIFU. Also, in the CJ series, contact instructions can be differentiated. In classic input mode, look in the bottom left of the dialog box. gtsuport
  12. I have an old Fanuc SeriesONE PLC which will be replaced with a new Omron CJ1M The SET OUT RESET instruction is used in the Fanuc PLC program. Is there an equivalent of such instruction in CX-Programmer?
  13. so instead of Calling the file .txt in my citect setup, I name it .csv and it could work? Sounds to easy, Any other feedback? I will ofcourse try,

  15. Capture snapshot of I/O data for simulation

    I only need it to be a static configuration that can be manipulated manually. How do I write the XFER instruction to load the .mem file into cio like you suggested?
  16. L Series CPU Program Transfer

    i have a cpu containing the original project, and i have another spare cpu,  the main problem appears when we write the program to the new cpu the simple motion module error LED is flashing and the machine isn't working well So, i want to know an ideal and safe method to replace the cpu without affecting the setting of the intelligent function modules (Motion and temperature) especially during the (Write) process

    Better have a backup of your project if you go clearing PLC memory.
  18. Cx designer not supports test simulation with cpm2a/cpm1a

    What are you trying to do?  CX-Designer is for the NS-Series HMI, not for the PLC.  And NT-Series Support Tool is for the older NT-Series HMI.  To talk to the PLC you need to have CX-Programmer.

  28. Hi, I just want to log data or save tags in generated excel/csv log files, how do I do this? are there any guides for a dummy? I succed easilly with txt and rtf docs but not excel/csv, Any tutoriols or guides?
  29. Kinetix 3 firmware

    Sorry for attaching the wrong doc. I have too many of these things on my laptop but you clearly found the correct manual and page. I think the solid green on the top-center diamond means the 1203 has power and is transmitting or had transmitted data. Green flashing means on, but no data transferred. Either way, green is good.  I've never seen a 1203 go bad from changing the settings. If you've pooched the settings and it's decided to stop cooperating, try this: unplug it delete the driver from RSLinx and shut RSLinx completely down. You may have to use RSLinx Classic Launch Control Panel go to your laptop Device Manager, Ports & Comms and make sure the device is gone then re-create the driver in Linx and start over When the 1203 is connected to and communicating with the drive, it should look like the picture at the top of page 3-5. The "workstation" is your laptop. The "AB/DPI" is your 1203/drive; it doesn't show up as an actual drive the way it would with an RSLinx EtherNet connection. Once you have that you should be able to get online with the drive with CCW, so long as you have a Kinetix drive installed in CCW with V2.0. From there, you should be able to flash up to the higher FW. "Should".
