  3. Dear, Since a few weeks I started working with the Vision PLC 430 J T 2. I have three expansion modules (2 for analog inputs and 1 for load cells). Recently I've started writing down the logic of my final program. Until now I only have experience with the Siemens S7 with associated software. I want to create a sequence where the transition from state to state is based upon conditions. Only one transition can be true at any point and the sequence is always the same. I've always done this with flip flops which set and reset each other. Now I’m searching for the correct way to implement this into the Vision software. Can someone advise me on this? Thank you in advance! Nick Verlooy
  4. Hi, I have Unitronics PLC V130-J-TR20 PLC, which is a master, and two Jazz JZ20-J-T40, which are slaves. I need two of the slave Jazz PLC's to communicate with master V130 PLC. I have made configuration in PLC Program for read and write, but it's not working properly. When i set bit for request to read PLC3 (MB100), it reads it normally. But, when i try to read PLC2, it reads same value that I have on PLC3, although Communication is OK with PLC2. I have read example project, and used it to configure communication between PLC's, like you can see in the images. Regardless of what I do, one of the PLC's is not working properly, communication says it's OK, but keeps reading values from other PLC. IP addresses are different, of course, and i have typed them correctly into the MODBUS IP Configuration, like in the image. On my Jazz PLC's I have done everything like Example project in U90 Ladder says. Is there a way of fixing this? Thankful Nikola Ljubinkovic
  5. The greatest task of last year for our company was a project of replacing old control systems (mainly KOYO) on nine hydro power plants in Lithuania. Our goal was to replace old control systems (nearly 20 years) with new ones, fulfilling actual demands for operator comfort, reliability and ability to communicate with external devices. Furthermore, there was requirement for decommissioning of old equipment, replacing most of cabling, and installation of new control systems in shortest possible time in effort to minimize economic loss. UNITRONICS Vision 1040 was our best choice for that task. Finally, thanks to precise cooperation with our customer, we were able to plan the whole action for really short time, and above that, keep the schedule without time loss. Beyond the replacing of the control systems, we were able to equip the control systems with SMS ability and to connect them to the internet for future remote access. We used Cinterion TC65i modems for SMS communication; and Lenovo mini PCs with 3G USB sticks for connecting technology to the Internet. Software: There is Remote Operator installed on every PC along with DataXport for collecting data from technology. Notable fact: The whole mission took less than 30 days for only three employees: Project Manager, Software Engineer and Electrician.
  6. Does anybody know if Vision controllers (ie V130) support Modbus TCP or do they support the Modbus RTU over TCP implementation. The difference is that the first follows the original Modbus TCP frames (ie no CRC) while the latter encapsulates the serial RTU framing sent over TCP media. Which one is supported by Vision and the other Unitronics controllers?
  7. Hi all, at the moment i am using a Vision350 Controller for a small machine type. We think about replacing the Vison350 with the new 7 Inch samba. Now i have a few questions, because i am not sure if the memory of the samba would be enough for this program. * How can i find out the memory used in the Vision350 controller? I already looked at the "project memory map", but i did not get really useful information from there. I only see that i am using 4,9 % of the DLU capacity, but i do not find any information about how many kb are used for ladder code, hmi variables, .......... * Is there any way to export my code from the Vison350 and reimport it in Samba? I already tried to change the hardware in the project, but it is not possible to keep the hmi screens and the ladder code..... I also tried to export the ladder subroutines one by one, but also here the import is not possible, because i always get the message that some used operands are not available on the samba platform. Of course i have to re-adress some variables, but it is just not possible if i cannot import the subroutine in my samba project. Any tips would be helpful, as i think that this small project would fit in the Samba models. And using a 7 Inch display would be better than the 3,5 inch from the Vision. Thanks BR
  8. Hello, I'm just wondering what is the best way to log some informations. I will need following: Login/logout, battery low - switched to charging mode and so on. I will need to have separate display and the log should have time and thing that happened. It will probably have to be in table because it suppose to have "history" feature, like you can list back in time and see what happened. I've been searching for answers in help feature, but i still don't know how exactly do it. Any advices are greatly welcome! Sorry for my bad english. Best regards, Martin P.
  9. Something I would find, and hopefully others, would be a way to print out the Drum configuration(s). I was unable to find a method for printing it, unless I'm looking in the wrong spot.
  10. Hey folks, new to PLCs and new to this forum. ---- Ok, so this is my issue: Boss wants me to hook up a 350 to an IRC5 ABB controller, preferably through an ethernet cable. No fieldbus adapter on the controller. No devicenet on the PLC. ---- I'm looking at modbus, but I do not really know where to start. ---- What's the recommended protocol for this situation? What kind of programming is involved? ---- ANY help at all would be awesome. Thanks in advance!!
  11. OK - This post is hard for me, because my english isn't good. I programmed many functions using SD card, and i've found some bugs: 1) Write Delimited Line to Excel Nobody using this function?? Really? OK - first useless thing - writing all 512 bytes to SD Card. OK - some O/S limitation. OK - I create buffer, fill this buffer with data using Create Excel Delimited Line, and bum! - 2 hours of debugging !! V1020 can't write all 512 bytes to SD Card, if there is no null value at the end of buffer - but I'dont want to have in CSV file null bytes, because Excell and other software go wild Then I ask - what is for "Write Delimited Line to Excel" because now is useless. I must used SD File Utilities (Open, Write and Close SD File). 2) Changes of Write Delimited Line to Excel Write to file not all 512bytes of data, but specific amount of data without zeros (null values). 3) Create new Excel functions would be nice: a) write/read trends to/from CSV file write/read data tables to/from CSV file 4) Create new function of Folder Report - list existing files. I want to create custom SD File Card Browser because originally isn't pretty, but i can't because i don;t have any possibility to list files in folder.
  12. Having analyzed our 2010 sales, looking particularly at areas of dynamic growth, we are increasing our inventory of Unitronics products. The increases will be seen mainly in the Vision Series of OPLCs but Snap I/O modules and Expansion I/O modules will also be increased. 2010 was a great year for us, in no small part due to the growth we saw in Unitronics sales. This is nice to see because it comes as a direct result of the strategy of increasing our presence on the web and emphasizing the quality, features and value of the Unitronics products. The control system design and electrical control panels side of the business has also been partly responsible for the growth so it is accurate to say our 2010 sales were balanced very well between standard control system components and electrical control panels. The Unitronics product line will continue to be one we emphasize in 2011 so we are in the process of ramping up inventory levels. This may take several weeks but shortly we will have a broad representation of V130, V350, V560, V570 and V1040 PLCs along with a good assortment of I/O modules on our shelf. Our goal is to fill orders for our OEM customers directly from our inventory and have all the most common PLCs available even if it’s not one currently used by one of our regular customers. Unitronics Vision, Jazz and I/O items we will stock include… V130-33-R2 V130-33-RA22 V130-33-T2 V130-33-TA24 V350-35-R2 V350-35-T2 V350-35-TA24 V560-T25B V570-57-T20B V1040-T20B V200-18-E1B V200-18-E3XB V200-18-E4XB V200-18-E5B V200-18-E6B EX-A1 EX-RC1 IO-AI4-AO2 IO-ATC8 IO-D16A3-RO16 IO-D16A3-TO16 IO-DI16 IO-DI8-RO8 IO-DI8-TO8 IO-RO16 EX-D16A3-RO8 EX-D16A3-TO16 GSM-KIT-41J V100-17-ET2 V200-19-ET1 JZ10-11-R16
