  1. Capturing point using a 512MB Memory card

    Hi Melvin, The good thing is that you could implement this on a CF memory inside a CJ1 or CJ2 PLC. You must consider that each "data saving procedure" takes a lot of time (maybe around 1 s or even more). You should make a copy of your datalog with longer intervals. You should consider to save a long array of logs instead of saving individual ones. I recommend to look inside the programming manual in order to find the suitable commands. Regards,
  2. Is there such a thing as small CoDeSys PLC?

    Look at this: I think that this is the closest brick PLC. It's price is around 200 € for a bare PLC.
  3. Hello everybody! It's the first time I use an SD memory on an ABB AC500-eco PLC. I need to store and retrieve some events in an installation and keep a user's data base (something like an access control). I may need to store around 10.000 users (each user needs 6 bytes) and any number of events. I had been trying to use SD_WRITE and SD_READ instructions, but it is really very frustrating whenever the CPU hangs ups (the RUN led stays forever flashing, which means access to SD), the SD loses the "USERDATxx.dat" file or the SD command returns a ERNO code like 4095 (there is no tag in the datasheet about this failure). I'm waiting for all DONE signals and I avoid to run more than one SD command at the same time (just looking at their ENABLE inputs). I would like to use SD in CODESYS as the standard C functions to open, write or read files. I have found SysLibFile library but there is not too much documentation. I hope that this would make me life easier. Can you help me? I need its manual (or specification) and an example. Thanks in advance!

    Hi! We have been contacted by UK's Aerotech brand. I would like to know if someone has contacted them and what were his impressions. I mean - Product quality and performance - Technical help - Price Thanks in advance! Best Regards, SUBY
  5. Omron's Servo

    Hi! Just look at it. It's easy to understand what it is suggesting you: Different control methods for your controller in order to make your servo move. It's just your wiring! CW+CCW means that your controller gives any of them when running. CW is given to turn your servomotor clock-wise and CCW to turn it counter clock-wise. PULS+SIGN means that your controller gives a pulse train for speed and a PULS for sign (turning clockwise or counter-clockwise). To turn your servomotor slow your controller must send a low frequency signal (let's say 1 Hz). To turn your servomotor fast your controller must send a high frequency signal (let's say above 1 kHz). As you may imagine, this depends on your GearBox parameter setting (parameters Pn20x). Good Luck! SUBY

    I think that I've found it but I need further tests. It seems that "Interrupt Feeding" bit cannot be set while performing an "Absolute positioning". If so, there's an error code 3050 "Multistart error". The only way to set it is at the same time.

    Hi all! I'm working on a project update with three JUNMA servodrives linked to a CJ1W-NC471 (it's an NCF71 card for 4 axis instead of 16!). I have succeeded with jog, origin search and absolute moves, but sometimes I get error code 3050 "Multistart error". It seems to happen always when I execute an Interrupt Feeding and an absolute positioning. Has anyone experienced this? According to the W426-E1-07 manual at section 9-5, I must turn on the INTERRUPT FEEDING bit and then start ABSOLUTE MOVEMENT. Any idea? Thanks in advance!

  9. Regarding your question, I think that LENZE is a good solution for machine builders. You can get high quality and reliable solutions for a competitive price. The old 8200, 9300 and EPL have most of the communication buses available as an extra card, but all include CAN bus as an standard. When building machines with several small servodrives, ECS is a good option. I haven't yet worked with 8400 or 9400 drives. Someday... Regarding your points, - SERVICE: it is good (almost in Spain); - RELIABILITY: servodrives are good and strong enough. 9300 drives are strong and there are no plugg-in cards (not like CT or others) and you can cover most of the needs for machine builders; All brands have problems and nobody is an exception. - PROGRAMMING: This is the complex point. You have two options: - parameter based products with an specific firmware (positioners, standard drives, camprofiles, ...); - codesys based products (servoPLC's and EPL-10200 PLC) with libraries. When using parameter based products, you just buy an specific firmware (it's like a licence) and only LENZE is able to change it through a download. Documentation in English and German is good. Less documentation in Spanish. Programming under codesys environment is like other brands: no upload from end-device is possible. Unless for large series machine building, I don't recommend to program the EPL-10200 PLC. Just use any other PLC with CAN like VIPA 214CAN. Regards,

    Maybe it's a bit late for an answer but I think that your problem is that the TJ1-PRT is able to handle only 16 words to each way: I mean 16 output words and 16 input words. Did you try this?
  11. OMRON CX Supervisor and OPC

    Hi again! Indeed when I wrote this project, I followed al the steps shown in your link. Unfortunatelly there was a failure in Cx-Supervisor between 1.22 and 1.24 releases and the OPC as shown in the link did not work at all. It is important to use either versions below 1.21 or above 1.30. OMRON had no answer for this issue. Anyway, if you need further information regarding this issue, do not hesitate to contact me. Regards,
  12. OMRON CX Supervisor and OPC

    Hi all! Three years ago I succeeded connecting Cx-Supervisor with a LENZE OPC server (called DriveServer). Like you I had lots of problems because of the Cx-Supervisor versions and all them were solved with Cx-Supervisor version 1.30. Be carefull with Cx-Supervisor releases! There are always changes and some features (OPC or some calculations) stop working. In order to check your OPC, I recommend you to use an OPC explorer (just another OPC client!) and you see it your OPC is properly set up. If you needs it, as soon as I go to the office, I'll upload my notes and an OPC client. Unfortunatelly everything is written in Spanish. Your problem with scripts points again to OPC link. Good Luck!
  13. Should I Use Function Blocks?

    Hi all! Just one small thing regarding FBs with OMRON PLCs: Look at the PLC Memory utilisation at "View/See Memory" (UM's). Sorry but I'm using Cx-P in Spanish! Sometimes when using big FBs (i.e. with floating point calculations) or just Omron's made FBs (like those for Mechatrolink or DeviceNet), the CJ1M's PLCs become small and you need bigger PLCs (CPU43 or higher). FBs are a good tool to avoid typical problems caused by "Copy & Paste" programming whenever you need to use several times the same routine, sequence or steps, but be aware of Memory (UMs)! OMRON PLCs were not block oriented like SIEMENS. Best Regards! SUBY
  14. Small siemens PLC

    Hi! Why don't you try with a VIPA System 100 PLC? Look at it here! I copy its features: "The VIPA system 100V is a Micro-PLC system programmable with Step®7 from Siemens or WinPLC7 – a programming tool from VIPA. With a compact design, system 100V provides a maximum expansion of up to 160 I/O points by plugging in expansion modules. These Micro-PLCs are especially suitable for use in smaller and cost-conscious applications." Really you are writting your program as a S7-315 CPU under STEP-7. Your application looks much more serious, faster and expandable than with a S7-200 PLC. And price is over the same level... What else do you need?
  15. S7-414 to S7-315

    Hi all! You can try to transfer this program to any VIPA SPEED7 CPU. As far as I know, these CPUs have the same 4-level stack as in the S7-400. If your application uses any technological SFB (for instance, position control loops, frequency meter, ...), it will fail to compile and you will need to write it by your own. Best way if possible, it's to try it! And don't forget to tell us your results. Regards!
