  1. OP37 MPI address random

    Thank you Jasper, these are the answers: >>If you check the application in Protool, is it set to the correct MPI parameters, in particular baudrate ? Yes, it is set to MPI add.=1 . >>Is the cabling correct ? It is the statndard cable. >>What are the distances, and what kind of cables and connectors are you using ? They are under test and the cables are under 2m. >>If you connect directly to the OP37 without the PLC, what happens then ? I have an MPI adapter and can't connect it to OP without PLC connected. >>Did the panel ever work, or is it a new installation ? The panel has worked and was OK. >>There is a small dipswitch next to the MPI/DP port on the OP37. It can be set to MPI/DP and >>RS485/RS422 respectively. Is it set to MPI/DP ? DIP switches are set for MPI/DP connection.
  2. OP37 MPI address random

    Hi, I have an OP37 panel. The panel can't communicate with the S7-300 CPU. I used the SIMATIC Manager 'Accessible Nodes', the online connected MPI nodes are always the address 2 of S7-300 CPU and a changing MPI address of OP37. That means, every time I check the 'Accessible Nodes' the displayed MPI address of OP37 is different from the last displayed address. It is random. Any idea? Thanks
  3. op17

    Hi, If you want to transfer the program from one OP17 to another one. it is better to use the Prosave. Good Luck
  4. Td 17

    Hi, Have you still interest to know the answer? To maintain communication between TD17 and a S5 115U , you need a special FB form SIEMENS. Please write your Email to contact directly.
  5. Communication Between S7-200 And Pc Through Rs232

    Hi, Is it possible for you to send the rest of document(doc1.doc) too?
  6. OS2 and PL7

    Hi Lazy, that is great and a big help. I copied the image file to my hard disk partition and now the computer boots under OS2. But athere is a problem, the XTEL wants a user ID and password to start. What is it?
  7. Installing Hardware Updates

    Hi, I have SIMATIC Manager V5.2. I want to update the Hardware Catalog in order to add a new module from SIEMENS. The module part No. doesn't contain in HW Catalog. I did it using Internet connection and now I have an XML file and many update files. Now I'm trying to update another computer using this file, but it happens nothing and the updates don't appear in the window. I tried also using the internet again on both computers, but the message "can not create target file" appeares. I used the command "Option\Install HW Updates.." in Hardware configuration package. I also tried the file "HSP2005_11.exe" from Siemens support center, but it happens nothing. Any Idea?
  8. Connecting two MPI adapter to one PLC

    Hi jacked, I tested it. As I wrote, It doesn't work.
  9. About S7300 program documentation

    JasperMP is right. This is from SIMATIC Manager help: Storing Project Data on a Micro Memory Card (MMC) With STEP 7 you can store the data for your STEP 7 project as well as any other kind of data (such as WORD or Excel files) on a SIMATIC Micro Memory Card (MMC) in a CPU 31xC or a programming device (PG)/PC. This allows you to access project data with programming devices that do not have the project saved on them. Requirements You can only store project data on an MMC if it is inserted in the slot of a CPU 31xC or a programming device (PG)/PC and there is an online connection established. Be sure that the MMC has enough capacity to accommodate all the data to be stored on it.
  10. Connecting two MPI adapter to one PLC

    Hi JasperMP, I use a Noteook as programmer and I'm not so rich to buy a CP5511 too. I have the pinout of the MPI-Adpter and have tested it with external +24 and +5V, but no success. there are two pins on MPI adapter and MPI interface of CPU. One is RTSAS and the other one is RTS_PG. I think the problem is due to these pins. This is from MPI-Adapter manual: RTS_AS: RTSAS control signal for receive data current. The signal is active ‘1’ when the directly connected AS is transmitting. RTS_PG: Adapter’s RTS output signal. The signal is ‘1’ when the adapter is transmitting. I solved the problem as follows: The CPU, I'm trying to connect to, is a 313-2DP. I used the DP interface to connect the PC MP-Adapter and the touch pannel is connected through MPI port to CPU . Thanks for you interest and replies.
  11. Connecting two MPI adapter to one PLC

    Hi JasperMP, As I wrote, there is only one PLC and the PC that is connected through USB MPI-Adapter to MPI Network shows the "accessible nodes" using SIMATIC Manager. That includes the MPI address of Serial MPI-Ad. and the address of PLC. Any idea?
  12. Hi, I have a touch panel connected to an S7-300 PLC via SIEMENS serial MPI adapter. I want to connect my PC via another USB MPI-Adapter to the same PLC. The serial MPI-Adapter is operating OK and is always Online, but when I try to get the status of a block in PLC from PC, it comes no response from PLC and the USB MPI-Adapter hangs. I checked the address of both Adapters and are different. I used the command "accesssible nodes" from PC and I see the MPI address of Serial MPI-Adapter and the PLC. Any sugesstons? Thanks
