  3. KWH Meter

    Hi, I am looking for some advice, I have a kwh meter that pulses in watts, and i am looking to display this on a GOT2000 screen I know I have C and LC, but once the count has reached K9999, will it auto reset. 7W

  6. I've set up 20 or so of my alarms under the 'User Alarm Observation' section. I then added an 'Alarm Display (User)' object. Will this object display my alarms when they come in? I'm noticing an Alarm ID section in the 'Alarm Display (User)' object section. What is this Alarm ID for? Can the 'Alarm Display (User)' object only display one alarm? That doesn't seem to make any sense? How would I got about configuring this object so that it will show all my alarms as they come in? Thanks!
  7. spring only gets to do something after there is no more current in the coil (magnetic field collapses). as long as coil is energized, spring is not in control. so after output is off, current still flows through solenoid (but now it is going through diode, not the output). this is due energy stored in solenoid and duration is affected by characteristics of suppression device. and as mentioned already, connecting MOV or Zener across solenoid will not produce any meaningful difference if output has own built in diode (and normally they do!). and if not but you choose MOV and Zener with too high breakdown voltage, the output device will get damaged.   
  8. Measure carefully.  The bulk of the time caused by the diode will be between output turn-off and the valve beginning to close.
  9. NX1P2 EIP with Siemens S7-1214FC?

    Look like it is available if you are registered on their support website: Alternatively you could try the Omron Generic EDS file available on this site which works with most devices.
  10. Hi. what i've gathered, i need an EDS-file for the siemens s7-1200-system to be able to specify an ethernet connection in sysmac from the omron plc side to connect to the siemens ethernet/ip server. Anyone know where or how to get an EDS file for the siemens plc so i can import it into EIPprofiles in sysmac?
  11. Thanks for the reply. I still need to figure out how to get that pattern values into my PLC program, but that is (in this case) a more specific Modicon question. You are right about the Modsbus RTU being too slow. I have used Modbus in the past to provide corrections to a robot arm in real time, but that was Modbus TCP. I mixed the two up. Modbus TCP should be fast enough, depending on how effecient the PLC is at getting that signal out there. Direct connection to the PLC would not be the preferred option because of all the cabling involved. A RTU would be a much lighter and simpler option. Regarding the coils: currently we use a normal flyback diode, and this achieves a 7 ms closing time. I will investigate using a MOV or Zener in the design, but I believe not the coil, but the spring inside of the valve is the limiting factor wrt the closing time.
  12. Sysmac Simulator questions...

    I recall seeing a slider in the simulation tool window where you can slow down the simulation, check if its set to normal or slower.  
  13. Last week
  14. Well, the coil is the item storing energy, and producing the reverse voltage when the driving voltage quits.  With a diode, the reverse voltage peaks at ~0.7V.  With an MOV, that reverse voltage peaks at the MOV's breakdown rating. With neither diode nor MOV, that reverse voltage peaks at spark initiation in the wiring, or at the failure reverse voltage of the driving circuit. For the pedants among us engineers. (:
  15. How to combine 2 different WORD to create a single FLOAT

    Re-write from DB to global MEMORY your word like DBx.DBW1>>MW10 and DBx.DBW2>>MW12, then create real format for global memory MD10 (it take's 2 words)   Have a DWORD value. Load the high word value into the DWORD. Shift the DWORD left by 16-bits. Mask in the low word into the DWORD. User DWORD_TO_REAL conversion to convert it to the real value. MyDword := HighWord; SHL(IN := MyDword, N := 16); MyDword = MyDword AND LowWord; MyReal := DWORD_TO_REAL(MyDword);
  16. a very good point, i would add that MOVs do not apply reverse voltage, they are passive component and do not store energy - they just conduct more at some higher voltage. depending on used product, this value is different. the higher the clamping voltage is, the shorter the pulse is (turns of faster). diode has Vf of only 0.7V so the clipping on 24V solenoid occurs at 24.7V. That is extremely low and takes longer to switch off. But with MOV it may be at 36V or so. using Zener diodes one can get the same effect which is why there are several options to choose from.
  17. One more note:  when switching solenoid coils that fast, use heavy-duty Metal-Oxide-Varister suppressors on the coils instead of flyback diodes.  Flyback diodes greatly lengthen the time it takes for solenoids to turn OFF.  Probably too much for 10ms cycles.  MOVs apply reverse voltage to the coil such that they turn off about as quickly as they turn on. Some digital output modules from various brands include flyback diodes right in the digital output.  You must not use that kind of output module, for this same reason.
  18. This sounds like a typical PLC application.  You will almost certainly be disappointed trying to switch valves that fast with Modbus RTU.  You will want those coils wired individually to output modules mounted directly to the PLC's CPU. I'm not familiar enough with the Modicon family's motion control capabilities to know if it will be responsive enough.
  19. Hello, quite new to PLC's, currently figuring out if / which PLC is the way to go for my application: I'm construction a machine with a two axis (X/Z) with 88 valves mounted on them. The X axis makes a scanning motion, and after every pass, the Z axis moves down 2.5 mm. When the X-axis moves, the valves need to switch in a certain pattern, opening / closing with a resolution of 2.5 mm, based on the current X and Z-position (i.e. encoder values). My goal is to move around 0.25m/s, so they would switch around 100 times per second (i.e. every 10ms). I want to be able to upload the pattern via Ethernet connection from my PC. The valves will most probably be switched through a Modbus RTU digital I/O unit(s) I ended up with the Modicon M241 as a nice PLC with the right I/O capabilites and features for my application. However, I don't know if it is suitable, as I am unable to find out how the whole uploading a pattern to memory, and then retrieving values one by one from memory during operation would work (i.e. which instructions should I use in my PLC program?)  
  20. Port 2 looks like it has all the robots on it, all the ECC203's appear to be on other ports. Is that correct? Roughly how long are the EtherCAT cables? are we talking 2-3m (ie. between nodes in a panel) or more like 20+ (ie. connecting nodes in separate panels? Are the cables shielded? Silly question I know, but got to ask  Judging by the screenshot, I would assume you have multiple EtherCAT cables from various locations running back to a single point. I assume it isn't possible to eliminate the JC06 for testing?   Most of my EtherCAT experience is with ECC203's and VSD's in motor control centers, I haven't really used it outside of the confines of a switchboard. That said, I would imagine it would require the same type of installation conditions as regular CAT6 cabling (ie. seperate from power cables etc.) to avoid interference. Would it be safe to say the cables are seperated from power cabling (particularly VSD driven motor cables)? 
  21. The DataType# is required more often in Ladder. Especially when the Fun/FB input has no datatype defined. (Says Any) It has something to do with the compiler checks for Ladder.
  22. Sysmac Simulator questions...

    There is a folder for the SD Card Simulation. C:\windows\OMRON\Data\SimulatorData\Card\Memory001 As for Simulation speed you need to have admin rights when running Sysmac Studio. From the Simulation menu - Calibrate the Simulator and then run in Time Estimation mode.  
  23. SAIA PLC - Modbus TCP truncates 32 bit value

    I've recieved it. Thank you. I will try to do some work tonight, and I will post results.
  24. SAIA PLC - Modbus TCP truncates 32 bit value

    Right, I thought you might have created some since your post. Check you PM, I sent a small program.
  25. SAIA PLC - Modbus TCP truncates 32 bit value

    As I stated before, I never had experience with FFP - I was just reading FFP datasheet. If you can send me two examples of FFP values, represented in real format and bit values I could try to do it in ST. Just for fun and it may help to OP.
  26. Mitsubishi GTDesigner 3 Alarm Ack Bit to PLC

    Perfect! Thanks so much
  27. In the project its set to 1000 meters on the Master Ethercat node.  
  28. I have had a similar situation in the past, the setting for Total cable length on the master was set too low, it might be related? 
  29. Hello Be. Before the cables and the JC06 was exchanged, it did happen that the communication could die during operation. But after all the ethercat cables was exchanged and the switch exchanged for a new, the communication only fails during power cycle of the whole machine. All the ethercat cables are prefab's. According to people memory, it seems to happen on any random port/chain, but last week, i only saw it on port 2 happen.   Here is the hardware config of the Ethercat nodes.
