  1. In this case Crossbow gave you right answer.
  2. Floating Pt from HMI

    for floating point format/operations you need to use _REAL blocks.
  3. Current Version of UnityPro supports Win10, so the USB driver should work too. We had many PCs with Win10 and UnityPro and have no problems.
  4. Hi Muddasir, which UnityPro version do you use?
  5. without any error code it's not really possible to find out the reason for that.  Did you try to establish the connection via ExecLoader?
  6. HEllo Dim,   are you sure, that your controller was programmed with ProWorx NXT? - Maybe ProWorx 32, Concept or UnityPro? Try to use OSLoader or ExecLoader to read the used Firmware.  
  7. you can place many XXMIT  blocks in your application, but you can use only 1 XXMIT in the same time
  8. your problem is following - only 1 plc of each HSBY system is connected to each switch - > that's definitely not normal and I never saw such execution till now. Normally both switches must be connected and build ring topology to obtain the redundancy.

  10. Hello Tiger, I see many possibilities: 1) connect both switches 2) use only 1 switch 3) read status of PLC (PRIMAR or STANDBY) and switch the IP address for READ/WRITE blocks
  11. Hello Tiger,  sure, it doesn't work after HSBY switching - the IP's on your diagram for STANDBY plc are wrong. During switching the PRIMARY and STANDBY plc change their IP addresses. So if you read from IP 192.9.200.12 (PLC A PRIMARY), then it's working - right. But if PLC A is in STANDBY modus, then this PLC A get IP address 192.9.201.13 and you CREAD_REQ will not work.  
  12. It's easy. In quantum Rack you have NOE771xx (I hope), which placed in slot X. So, if you are using READ_REQ/WRITE_REQ, in WordArr5[1] you need to put 16#0X00. X - is slot in Rack :)
  13. SR1 seems to be very rar and this release had many patches. I provide you a link via pm.
  14. may be it make sense to tell us which software do you use? Most software providing already working ramp blocks..
