  1. 1 slave to multiple masters

    You can extend your bus by multiple devices, and for example you can add a gateway like the one you have linked. But to configure these new devices/gateways you need to access the master on the bus (probably the Q-series?). So yes, it is possible, but you need to configure/program the master first. If you can change the configuration then you can change the bus.
  2. Yes, a SCADA will certainly solve your case. However, SCADA systems can be pretty expensive and you don't have a lot of data you need to collect (and for that matter you don't really need all the functionality that a SCADA system delivers), so I was just thinking if there were any other possible solutions. Regarding a SCADA system, head over to HMI/SCADA section of the forum, maybe someone knows of a "small" SCADA system that can handle your data. 15*5 tags are not much, so you are looking for a small, but functional system. Make sure it's scalable since you might want to expand in the future (suddenly you have 15*10 tags that you want to monitor  ). Check out: http://forums.mrplc.com/index.php?/forum/37-hmi-amp-scada/  You will need Ethernet cards/boards for the PLC's to be able to collect data, there are some other alternatives but they will be more complex and more expensive so I'm not going into those at the moment. Your biggest "challenge" though is to actually access the local networks (LAN) where your PLC's are located. My recommendation is to set up VPN tunnels from your head office to all your locations. Do you have any way of "contacting" your remote sites, or are they completely "stand-alone" today?
  3. Elipse scada

    Discussing hacking/cracking of passwords in the forums is not accepted per the terms of service. And also: If your vendor is not providing a password for editing the scada, there's probably a reason for it... Maybe the vendor has intellectual properties or similar, in any way you need to deal with your vendor.
  4. Ahh, sorry, forgot to mention that Mitsu doesn't name the instruction "FIFO", but FIF.... FIFO's: FIFW = FIFO Write FIFR = FIFO Read If you look in your manual (e-manual viewer) for the R-series, under chapter 3-7-7.5 (Data Table Operation Instructions) you'll have more instructions to play with. Like FPOP (LIFO-style reading).
  5. Overriding user in gx works 2

    This is something I'm not aware of but looking forward to see if anyone have an answer to...
  6. You basically need a software for this, and it depends quite a lot on how many devices you have and how many alarms you want to monitor. So: How many PLC's (physical devices) How many tags in each device do you want to collect/monitor
  7. See here: http://forums.mrplc.com/index.php?/topic/34081-fifo-program-examples-for-mitsubishi%C2%A0plc-iq-r-r04cpu-using-gx-works3/
  8. If you put the instruction on the codepage, and mark it then select F1 it will open e-manual viewer with information about the instruction... What specifically are you struggling with regarding the FIFO's in the Mitsu?
  9. PID controller on FX1N in GX Works2

    That is not how the PID instruction works. You need to download the manual for the FX CPU (search Mitsubishi's website for manuals), and read about PID instruction. Then give it a go. s1, s2 and s3 are NOT kp, ti and td. They are parameter-sets, so you'll need some arrays with more data to be moved. Start with checking out the manual, and post any issues on the road.
  10. 1 slave to multiple masters

    No, not possible. One "type" of communication on the port will occupy it. Alternatively, you can add more slaves to the Modbus, but that involves the QJ71MB91.
  11. error during download GX WORKS2

    Try re-copying it to your local harddrive (from CD/USB/Network etc.), make sure you have enough diskspace, and be absolutely sure that you have all the files locally on your harddrive, then try again and post the result(s).
  12. Operation error

    And also: If you are using 2-wire, then 110ohm, 4-wire then 330ohm.
  13. Latching position and counting rotation numbers

    It's straight-forward. Most instructions you are currently using for integers have an "E" in front of them (like "EDIVISION", "EMOV".....). They indicate REAL numbers and can be used freely. Just remember that a REAL number occupies two 16-bit dataregisters, so if you use e.g. D0, then it will occupy both D0 and D1, so the next usable register would be D2. And if you have an integer that you want to convert to real, just use INT2FLT to convert.
  14. error during download GX WORKS2

    Did you copy the setup files to your local computer, or did you run them off a network drive/usb? I think you need the setup files to be locally when installing...
  15. Pointer In GX-Work2

    Not sure what you want to accomplish since P100 is a pointer (as you also say yourself). No matter if you use Ladder or ST, pointers are used for referencing other program parts, and sequence control, not to contain "values". What is it you want to do?
