  1. Hello, Can anybody help me with how to write an analog from an S7-400 to an IFM ASI analog output module (AC2521). I am using an IFM Controller-E (AC1305 Asi Master 1). I am very familar with using ASI for reading Digitals in and writing digitals out but I cannot find any information or white papers on how to write an analogue out and or how to set up the mapping. Rig is set up. Asi Master is node 4 which the PLC can see.(Module OK and Available). I have laid out the i/o mapping for the analog out area (Slot 11 of ASI-1 Master) and have tried to write a value anywhere from 0 - 27648 (0-20mA) but without response. The ASI-master is not even seeing the valvue in the 4 channel areas located on teh local display. Anyone any ideas? I don't think so but do I have to use SFC to write out the values? Anyone a white paper on this?? Thanks in advance.
  2. Hi all, Thanks for all the advice about my installation. Unfortunately I dont have that kind of luxury. The plant runs 24/7. They have scheduled 5 days downtime for maintenance and it is during this down time that I have to do my changeover. So fingers crossed that all goes well. I am building a test rig in the office to test my comms as much as possible so hopefully all will go smoothly. Jay
  3. Hi All I thought that while I was on a roll of asking questions I might as well ask another one. In my existing PLC5 code, double indirect addressing is used i.e. the data file and the word address #N[N30:30]:[N30:10] As far as I know, indirectly accessing the tag name cannot be done in CLX. So any advice on how to get around this, bearing in mind that the customer does not really want any more indirect code than I have to. I have started trying converting the first tag value to a string and trying to build the required tag name that way but have not yet got it to work, so any help would be appreciated. Thanks in advance Jay
  4. BobLfoot I have configured the Logix as per your advice and have attached a screen shot of it below. One thing that I have a question about is that For my Rack 3, you have said to assign the 3 Ana Ins and the 1 Ana Out to Groups 0,1,2,3 respectively. However, in the existing PLC5 code, the BTR's for these analogs are configured to look at groups 0,2,4,6 respectively. Is this just something that has changed in Logix or is there a different explantation. It is the same for all of the ana INs and OUTs. Also in the existing PLC5 Channel Properties it has Rack 4 and 5 as full racks whereas you have suggested 1/2 racks. I am not questioning your advice because you obviously know more about it than I do, I was just wondering why there would be differences. Also, thanks for your suggestions. I will create the alias tags because, as you say, it will make it an easier transition for the On Site service people Again, thanks for your help. Jay
  5. BobLfoot Thank you very much for your help on the matter, Your explanation was extremely helpful. Racks 4 and 5 are in a 16 slot chassis, sorry for not making that more clear..... About the DO cards, they are 16 out, sorry about that too.... Anyway, thanks again for your help....
  6. Hello Again, I am just having a few problems with setting up the configuration tree in Logix for my RIO Racks. So I was wondering if someone could help me. In my existing IO there is the following:- Chassis 1 PLC5 80E, RACK 0 DC Input 10-30V 32 In, DC Input 10-30V 32 In, DC Input 10-30V 32 In, DC Input 10-30V 32 In RACK 1 DC Output 10-60V 18 Out, DC Output 10-60V 18 Out, DC Output 10-60V 18 Out, DC Output 10-60V 18 Out RACK 2 DC Output 10-60V 18 Out, DC Output 10-60V 18 Out, DC Output 10-60V 18 Out, DC Output 10-60V 18 Out RACK 3 ANA IN 12 BIT, ANA IN 12 BIT, ANA IN 12 BIT, ANA OUT 12 BIT Chassis 2 1771-ASB RACK 4 ANA OUT 12 BIT, ANA OUT 12 BIT, ANA OUT 12 BIT, ANA OUT 12 BIT, RACK 5 DC OUTPUT 10-60V 18 OUT, ANA OUT 12 BIT, DC OUTPUT 10-60V 18 OUT RACK 10 1794 ASB, 1794 IB16, 1794 IB16, 1794 IB16, 1794 OB16, 1794 IB16, 1794 IE8 RACK 11 1794 ASB, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16 RACK 12 1794 ASB, 1794 IB16, 1794 IB16, 1794 IB16, 1794 OB16, 1794 IE8, 1794 OE4 RACK 13 1794 ASB, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 OB16, 1794 IB16, 1794 IB16 RACK 14 1794 ASB, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 IB16, 1794 OB16, 1794 OB16 In My CHASSIS 1, I am removing the PLC5 CPU and replacing it with a 1771-asb I have been searching on the web and found different opinions, some say that for the PLC 5 chassis's, I should have a 1771-asb configured for each rack, even though there is only 1 physical card. Also do I have to configure each card in each rack because in Logix, it only gives the option of a generic digital card or analog card. So if someone could give me some pointers for this configuration I would really appreciate it. Thanks in advance
  7. Unfortunately my customer does not want to spend a lot of money so changing to Control Net is not an option. And as regards update times, this in not really an issue because it is not a critical process that is being controlled. I am putting an exact copy of the IO config into the logix down to all of the analog card configurations (I am just copying the INT values from the PLC5 data tables and putting them into the Logix) It was just if there was anything out of the ordinary that I have to do in Logix that would not have been done in the PLC5 i.e Card initialization, IO mapping etc. Thanks in advance
  8. Hi all, I am starting a project where I have to convert a PLC5 plc to Logix 5000. The code side is easy, I just have a question about the IO. Currently in the PLC 5 main rack, there is the CPU and then the rest of a 16 slot chassis is taken up with IO. There is then a RIO link to a remote rack with a 1771-ASB adaptor with a full rack. The RIO is then daisy chained to 5 further Remote Flex IO racks with 1794-ASB modules and then full racks of IO. What I am attempting to do is provide a new CLX with a 1756-DHRIO card and then replace the PLC5 cpu with another 1771-ASB module and leave all the rest of the existing hardware. Is there any fore seeable problems with doing this? Also if anybody has any examples of this type of configuration in Logix 5000 that they could post I would really appreciate it. Thanks in advance
  9. Hi All, Was wondering if someone out there can help me. I am trying to setup communications between a logix 5000 plc and an s7 400 PLC over Ethernet. Is this possible, and if so could someone help me out with some pointers. Thanks in advance
  10. Hi All, lo I am Using PLC5 Emulate Ver.5 and I want to communicate over ethernet to a physical Logix5000 PLC. I was wondering if anyone has ever done this as I cant seem to get it working. I have done it from logix5000 emulator to a physical logix5000 plc and it workd fine....... Any help would be appreciated..... J
  11. Hello All, Wonder if someone out there can help me. I have RS Emulate 5000 Ver.15 installed on a PC with Windows 2000 Server SP4. In the emulated code I have sucessfully set up message blocks to write to and read from a physical hardware PLC using Ethernet. This all works fine and am able to test away... My Problem is that I am trying to repeat the process on a PC with Windows XP SP2 and it is failing.... I am guessing that it may be something to do with security on XP but would really appreciate any info that I get Thanks in Advance J
  12. Hi, I had already tried that and still doesnt work.... any other ideas would be appreciated though...... Thanks in advance
  13. Hi all, I need some help I am trying to set up comms between RS Emulate 5000 V13 on one PC and RSView V3.2 on another machine I have 3 CPU's configured and running in the Emulate SW. According to Rockwell Documentation all I have to do in RS View is add a new Data Server and Point it at the Emulator PC. I have done this and can see the Emulated CPU's and have linked my topics to the CPU's. This All works fine. My problem is that when I go into the Tag Browser, I cannot drill down to the CPU's tags. Its as if the tag browser cannot see the CPU's even though the Data Server can. Can anybody help me or point me in a Direction Thanks in advance
