  1. Remote connection using eWon

    Hi Wulfgar Thank you for your response, at least I know now I'm not the only one seeing this problem, the only slight difference is that I cannot download to the HMI's  
  2. Remote connection using eWon

    Hi All I am using a eWon unit to give me access to a remote network (IP range 192.168.0.***) using TIA portal V14, which connects to 5 S7-1200 PLC's  ,1 LOGO , 8 basic HMIs plus 7 other devices which are not of siemens manufacture. The issue I have is that if I am connected directly to the network I have no problems whatsoever, however, if I'm connected remotely using Talk2M ecatcher,  whilst I am able to go online, i.e download, upload, monitor etc  to the PLC's and other devices, I cannot connect/download to the HMI's' also if I use accessible devices in TIA portal it does not find any devices other than a PC on the local network (IP 10.0.0.***) , even though I can connect to the PLC's. If I ping the all of the addresses on the network I get a successful response. Anyone have any thoughts?       
  3. KTP400 password dialog

    Hi All   I have a issue with password dialogs on a KTP400 (6AV2 123-2DB03-0AX0) I am sure I am missing something somewhere but unsure as to what, what happens is whenever I press a pushbutton on the screen I get the password dialog, but there is authorisation is blank in security, also the event on the pushbutton still takes place without any password being entered, if the dialog is closed  and the button is pressed again , the dialog does not appear, any thoughts? 
  4. Basic HMI Graph

    Hello All   I'd like to display data in 2 or 3 arrays as a graph on a KTP400, does anyone know of a way to do this, I know I could use a trend display , the only issue I have is that the array will be updated in around 10 to 20 msecs per element, and as far as I am aware the time between the trend values need to be 1 sec or more. Any comments would be appreciated. 
  5. RsView Text Messaging

    Hi All   I have a client who has a SLC500/RSView system installed on his site, up until recently it has been using messenger to send text messages via modem and landline, now however the landline that the modem was connected to has been removed and the only connection we have to the outside world is via broadband internet, is it possible to send the text messages via the internet?   Thanks 
  6. PV600 Controller Choice

    Hello I am currently working on a system where we have multiple stations each comprising a Micro 850 and a PV800 HMI, the software on each is identical, the only difference being that the IP addresses will need to be different as they will all be on the same network for linking to a separate PLC. The plan is to have a PLC program with a default IP address that will be used to download to the PLC's, we would then use the Run Mode Configuration change to change the PLC's IP address , what I'd like to know, is there a way of changing The IP address for the controller in the PV800 in run time, or would the controller IP address have to be specified in the HMI before being down loaded? Regards.

  8. Pv800 download

    Hello All   Can anyone tell me if there is a way to restart/reboot a PV800 v3.01 from connected components workbench after downloading a new/updated application?
  9. SLC 5/05 on 2 ethernet networks

    Not sure if this will help, we use a unit called a cosy 141 from eWon it allows a PLC network to be connected to a factory lan network while keeping its own unique IP addresses, as long as the factory lan had access to the internet remote access is then achieved via a free eWon eCatcher account. http://ewon.biz/products/ewon-cosy
  10. AWL file

    The 'Structure' is the source code for network 1 of the ALARM PROGREAM function, if you compile this source file then open the compiled block , you should then be able to view it in LAD, this may make it easier to understand.
  11. Hi Schneider do a module to convert 24v signals to RS422 standard , it is VW3M3102 maybe that will be what you need
  12. Siemens and Modbus TCP

    The S7-1200 does have MODBUS TCP blocks included for Modbus coms over profinet, MB_Client & MB_Server.
  13. The meaning

    Basically L OB1_SCAN_1 - Loads value of OB1_SCAN_1 into ACCU1 (accumulator 1) L 1 Loads value of ACCU1 into ACCU2 (accumulator 2) , Loads 1 into ACCU1 ==I Compares ACCU1 with ACCU2, set RLO (result of logic operation) TRUE if ACCU1 equal to ACCU2 = 'New_start' make 'New_Start' = RLO R 'Re_Start' Reset 'Re_Start' if RLO TRUE
  14. mV Input to Analog Card

    Hi I would imagine the separate amplifier route would be the simplest solution, however depending on what your requirements are, siemens do have a number of modules dedicated to weighing functions , which have provision for loadcells typically the Siwarex-U would be a good starting point.
