  1. I am adding a remote device to an existing cc-link network. The master station is an A1SJ61BT11 and the CPU is A2USHCPU-S1. The CC-Link network currently has 20 remote I/O stations and I am adding a remote device. The A1SJ61BT11 has parameters written to its internal memory. In order to add my new remote device, I think I need to only change two parameters: First, I need to change parameter address H1 from 20 to 21 since my device will be the 21st. Second, I need to change station information parameter address H34 from 277 to 4373 to enter it as remote device. I looked at the example in IB(NA)-66721-J(0310)MEE, section 6.3. In the example, they are setting up the parameters for the first time. However, I am only changing two of the parameters. I followed the example except I only entered rungs to change the parameters for H1 and H34. My question: If I run the parameter setting program to only enter parameters for H1 and H34, will it affect the other parameters the original programmer entered? Could they go back to default? Any advice? Thanks in advance
  2. In my last plant, we used 100% Rockwell Allen Bradley PLC's. I was very familiar with replacing a SLC series with a 5000 series, a no brainer. Now I work in a foundry with 100% Mitsubishi A-series PLC's with a weird gateway coaxial loop communications that is way beyond it's service life. There is little no no support, and I have been tasked with updating it to something Ethernet based, and reliable. I would like to stick with Mitsubishi, for no other reason than to convert the code from the A series to the new series using my existing GX developer software. This is a running factory, no time to demo the old controls and spend weeks re-inventing the wheel with new Rockwell/Seimans/ect PLC's; plus I already have the software Despite a rather long learning curve, I've been getting comfortable using it. My question is: If you had to choose today what series to convert an entire plant, which would you go with, and why? Please keep in mind this is a foundry, its hot, dirty and nothing really needs to be high speed, or math intensive. I would like something easy to install, easy to expand, easy to use Mitsubishi HMI's and something the electricians can wire and repair (prefer screw terminals not spring terminals).
  3. Hi, I am trying to connect a CP1L-E to a NB7W-TW01B via a 5 port Ethernet switch. I have communication from the laptop to the PLC and from the Laptop to the HMI. but it seems like the HMI and PLC aren't communicating with each other. The HMI will not control the PLC. I've tried everything I know to do with the communication settings and it still will not work. If anyone has any suggestions they would be much appreciated! thanks
  4. G5 Series Servo Overload

    Hello, I am using R88D-KN08H-ML2 servo drive with R88M-K75030T-S motor. PLC is CJ2M-CPU35, with NCF71 position control unit. There are total of 6 axis and the one in question with above combination is giving me trouble, rest 5 work OK. I get Overload trip error even at 200% of torque. The motor doesn't move at all. After disconnecting motor power cable, it is possible to move the assembly by hand so nothing sems to be jammed or binding. Tried Auto-Tune, ended with successful completion (at least no errors etc). But scenario didn't change. Motor doesn't have brake, as per model number as well as physically no brake cable on motor. Since all other axes are moving, with similar setting, not sure what is going on here! Any parameters I can change? Any other way to check?
  5. Hello: I am new to Connected Component Workbench and Ladder Logic. I am using a ladder with 2 direct contacts on the first rung in series - the first is a N/O switch and the second is a N/C switch how do I make the second direct contact represent a N/C switch. So that someone else looking at my program would know right off the second switch is a N/C switch. Thanks My program functions as it should but the ladder diagram looks like two N/O switches in series.
  6. Dear experts, I used this forum for help analyzing our PLC setup in the warehouse in 2013 and feedback from the experts here was very helpful. I would like to offer an engagement as freelancer on our project since we need to cut-out a system which runs out of maintenance in Dec 2016. Please see attachment for details and very happy to receive any questions. I hope this is not against the forum rules as I couldn't find a suitable forum "job offers". Kind regards, Gunter Senior PLC Engineer Japan.pdf
  7. Load Cell FOR FX-series

    Can anyone tell me the part no. (P/N) for the Mitsubishi MELSEC-FX series programmable Load Cell
  8. Hi all and nice to meet you here! I hope that someone with experience helps me and I hope in future to offer also my help to someone. I am having problem with a Mitsubishi plc with A2N (S1) cpu installed on a machinery. The machinery stayed 20 days switched off and with battery empty as I realised when switched on and the problems come out. I changed the battery but the problem didnt resolved. The plc gave error with stable error led and flashing run led on the cpu. Also an error led stable on a (double role) module of printer and ram. I have to say that I have never used GX developer environment before and it is my first contact with Mitsubishi plcs. Reading some manuals (found on the internet) and by using GX developer I read from plc the faults. Register D9008 was set at 12 error meaning MISSING END INS. I Followed the described flow charts from a2n manual for reseting faults but the situation was the same always as described above. I tried to read the program from plc and succeded to read it. It is a lader with about 6000 lines. Anyway I have no previous experience of the GX development environment but I tried to put the missing END in the program as sugested also by the flow chart in the manual. At this point I have to say that it was automatically added from gx developer as I can remeber from an appeared message. I verified also many times the program on gx developer with the plc and the only difference was that missing END at the last line of ladder program. Anyway I tried to write back to plc the program with correct end but it was not possible. I tried several times. The error mesages took with Gx developer was the following : "THE SAME T/C COIL EXISTS IN PROGRAM (MAIN) AND/OR PROGRAM (MAIN-SFC). THE VALUES ARE SET TO BE THE SAME AS IN THE FIRST FOUND T/C COILFROM THE TOP OF PROGRAM" "THERE IS A DEVICE IN THE PROGRAM (MAIN) THAT IS OUTSIDE OF THE RANGE. CHECK THE PROGRAM AND CORRECT THE DEVICE THAT IS OUTSIDE THE RANGE." Anyway I decided to delete the plc memory. After that the run was stop blinking and the error led went off. Only the error on the printer-ram module was on (This module was changed with a know functioning one witout any variation on behaviour). I thought that problem has gone now that the cpu is empty. I tried again to write the program to the plc but again i take the above mentioned messages. Now I have an empty plc and a program on the Gx developer that cannot be written to plc!!!!!!!!!!!!!!!!!!!!!!!!! I am desperate!!! I do not know how to proceed. I am not knowing the mitsubishi development environment. Other than Gx developer I tried to install the GX simulation but it not works to my computer. At this point I dont know even if the ladder program is somehow corrupted after the described above messages. I can sent the code (GX developer project) and any other information to someone expert, if necessary, to have an opinion. Please help!!! Let me know how to proceed!! I have to write back the code to plc !!!!! Thank you all in advance!! Now i realised that there is SFC that is my problem. Could someone help please? Big part of ladder is in yellow color. How can i proceed?
  9. Hi, I am looking at options for integrating MATLAB/Simulink with Q-series PLC (Q04UDE) for hardware-in-the-loop simulations. I would like to have a Simulink model send speed/torque setpoints to the PLC and have measured values feedback from the PLC to the model. I know this can be done via OPC but I think the update rate may too slow for our purposes (I would ideally like to have <100ms update rate). Also, I saw Simulink have a toolbox for converting their models to PLC code, but they don't seem to support Mitsubishi PLCs. Anyone have any ideas on how this can be done? Thanks, Darren
  10. Dear Experts; I have already install a 10 slot chassis in a system. Now for the further process i need to add 5 slot expansion chassis for further I/O modules. I have now 5 slot expansion chassis part number IC693CHS398. But when i configure the hardware by using LM90 software i have not seen the option of expansion chassis. Image are attached. Please guide me how i install or cofigure the expansion chassis ? Regards
  11. String encoder

    I need to replace existing encoder with quadrature output which is failing. We need to have minimum measuring distance of 60 inches. The encoder installed by manufacturer is Temposonics R-series RHS0650UMSO1Q1AC10 The resolution can be lower than the current encoder, probably 500 counts/inch or higher would be OK. Do you have any product that can be used? I was thinking about string encoder but I am open to suggestions.
