  1. PLC to PLC Wireless Communication

    Hello lads, I wanna ask if anyone have attempted to connect two or more Omron PLC via wireless before, and if so how you manage that? My understanding so far is that one PLC should be connected by Ethernet Cable to a Wireless Access Point, and the other one should connected to a Wireless Client. After that the Client tries to automatically connect to the Access Point, then both PLC can communicate via FINS/UDP or FINS/TCP easily. I want to test out two PLC for now, but on actual setup there might be 10 Wireless Clients Any thoughts? Thanks in advance
  2. PLC to PLC Wireless Communication

    Thank you Sir. I had successfully tested this using AP to Client configuration. Might do other testing using Bridge mode.
  3. PLC to PLC Wireless Communication

    Thanks for replying! So in short it IS possible. Just to elaborate, is one of the wireless act as an access point? Or is both wireless act as a bridge between two LAN? Because AFAIK for multiple PLC, wireless bridge is very hard to configure, so I prefer access point method instead. I intend to use MOXA's wireless unit for this purpose. Bandwidth won't be a problem I think
  4. Creating a Special Array

    PLC got no random generator function as far as I know (something like the RAND function in excel). It should be possible using ST but you need to write your own code Random Generator code to create the random 0 and 1, then use another script to check the consistency with the percentage you've inputted, and recursively execute the script again. One site you might interested to check out for the actual Random Generator algorithm : https://cdsmith.wordpress.com/2011/10/10/build-your-own-simple-random-numbers/   PLC of course have the MOD function in ST, and regarding the seed you can use PLC clock seconds. But I'm sure it'll be a tiresome job :D
  5. FH-1050-20 & NA HMI

    Ah OK... Maybe in next japan semester... This year Omron just released robotics and the new delta-tau, so I guess IPC gonna wait
  6. FH-1050-20 & NA HMI

    Wo... is that out in the market already? Do you know the product code?
  7. CP1E MODBUS Maximum Slave

    Hello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance
  8. CP1E MODBUS Maximum Slave

    Hello Johanb, regarding cable length then the max actual device distance from the master should be 50 meters, I pressume? Regarding Danfoss modbus, I haven't tried to use this device before for modbus, but any modbus slave should have the same configs. If you are using latest version of SCU42, you can use the Serial Gateway mode to enter the Modbus commands directly to the PLC memory. For sample program you can refer to https://www.myomron.com/index.php?action=kb&article=577  which contains samples for Modbus-RTU using Protocol Macro.
  9. CP1E MODBUS Maximum Slave

    Hello Johan, thanks for replying. Well... whether to add repeater or not I think depends on the network load and distance right? My main concern is actually whether the PLC can address slaves whose unit number is more than 32... So far haven't got any exact answer for this, but as Jay said before, he can do more than 32 slaves.
  10. FH-1050-20 & NA HMI

    Normally FH is accompanied with a display screen, so image display on HMI will be unnecessary... Also Omron has launched new Touch Panel special for the FH series
  11. CP1E MODBUS Maximum Slave

    Thank you Jay. Yes indeed the manual state so. But I'm comparing it to the SCU41-V1 manual which clearly states only 32 slaves able to be connected. So I'm not really sure CP1E can do more than 32 @_@
  12. Conneting to Zebra Printers

    The SEND instruction will use FINS protocol through ethernet, which means the Zebra printer will receive FINS Headers. I believe you cannot made adjustment so that the printer able to distinguish FINS Headers and actual data. Your best option is to use the CJ1W-ETN21 as mentioned above since it can send No-protocol Socket Service data
  13. CP1E MODBUS Maximum Slave

    Bump!!! Anyone? :D
  14. Omron's CP1E-NA Using Mobus-RTU Easy Master FUnction

    For your first question, that won't be necessary.   For your second question, let's say you want to Read One Register, starting from Address 0000, from Slave Address 01 Thus your MODBUS data will be (in hex) : 1200 : 01 1201 : 03 1202 : 04 (4 bytes from 1203 to 1204 are to be sent) 1203 : 0000 (Register Address) 1204 : 0001 (Read only One Register)
  15. Omron's CP1E-NA Using Mobus-RTU Easy Master FUnction

    Error Code 80H would mean a Response Timeout, which can translate into : 1. Wrong Wiring. For this case check the wiring 2. Slave MODBUS function is not yet enabled. For this case check the slave manual 3. PLC MODBUS function is not yet enabled. For this case set to MODBUS Easy-Master, transfer setting, and restart the power supply
  16. Omron's CP1E-NA Using Mobus-RTU Easy Master FUnction

    Look closer on the Software Manual. There IS Response Data Memory Area explained there. If you are using the Built-in serial port, Command Area should start from D1200, and Response Area from D1250   Careful about the wiring. Omron RS232 Port is non-IBM Standard, so SD, RD, GND, and other wires placement might be different from BB's serial port. Look up to the schematic. You might need to make a special jumper wire
  17. Whole Forum Posts are Replaced???

    Thanks ctew! So the cause was a virus eh... That's very unfortunate... Hopefully nothing similar will occur again, or at worst we will lost those remarkable PLC laws :D
  18. Whole Forum Posts are Replaced???

    Sure thing... hopefully they have the history stored...
  19. Whole Forum Posts are Replaced???

    Actually it also occurred on posts which does not contain quotes as well... I checked on threads that I started which I know have no quotes inside the first post. And since no one have replied on that, I don't think quotes are the cause.   Wonder when this thread itself will experience same thing. LOLz
  20. Whole Forum Posts are Replaced???

    Thank yo :D I found out that these happened on Mitsubishi section as well :    
  21. Whole Forum Posts are Replaced???

    I mean this kind of post... I wonder what is this... Some original posts doesn't require any moderation at all, but why these show up? Haven't check other areas, but in Omron section there are plenty of these lingering around
  22. Hello go look for the =DT instruction. You can use it to compare the internal real-time clock memory (A352) with the set time required that you put in other memory
  23. Hello, unfortunately you cannot do that in CX-Programmer, either in Ladder Editor or Structured Text.
  24. Hi Vahe,   Wow, that one worked wonders! I thought that particular function is only for String input to array byte.. hahah Thank you very much!
