  1. CP1L Serial TXD Data Error

    Hi, I have a problem with serial communication (no protocol) using rs485 module, the received data is error. I'm using CP1L CPU, CP1W-CIF11 module as transmitter, and USB to RS485 converter as receiver. When I check the received data on PC, it's incorrect (bit error?). I just send 2 bytes data, 0x61 ('a') and 0x62 ('b'). My configuration: DIP switch CPU 4 = off, DIP switch CIF11 1 to 6 = on,on,on,off,off,off, 2 wire RS485. (I also attached the program and settings)   Could you help me to solve this problem? Thanks   Program and Settings:     Result:   
  2. Serial Port issue

    Sorry its long !! I am recieving text from a GSM modem for text msg Send and receive (SMS) works ok but would be better if I could make use of the start code and end code. This way I could cut down on all the crap that is received when a text arrives. I get this  CMTI: "SM",0 I have it stored into D80 and I have that trigger a TXD that sends AT+CMGRD=0 and that tells the GSM to send the msg (The 0 is the current msg in memory) ------ The problem is that there is Carriage  Return and Line Feeds in the received msg ----      AS below ((AT+CMGRD=0 +CMGRD: "REC UNREAD","+19028991212","","22/10/20,16:57:54-16"  Hello this is the msg  OK)) When the PLC sees the carriage return it stops receiving data. And I have no start code or end code setup. (I am using characters received) The way around this is to set a high  character count in the RXD (More than the actual msg (More than the msg length)   The main issue with that is I get garbage in as the msg gets bigger. Its unreliable. I clear the port after each receive and that helps but still get the odd garbage. (Never get garbage when connected to a terminal prg). Any Ideas???? ps Even the Start Code is unreliable as it will start receiving a few characters late. Rob

  4. Change Subnet On CP1L PLC

    I am trying to change the subnet of this CP1L plc. Currently it is at 192.168.250.*** and I would like to change it to 192.168.54.***. I already tried starting fresh by writing to the controller with ip and then putting my desired ip address after. When I try to write to the controller with a subnet other than .250 for example, the controller saves the node address(.13) but keeps the same .250 subnet which results in me being able to ping successfully but get no response from pinging Yes I did change my local network card when pinging different subnets and also did a network reset in CX-P after every ip change. Let me know if there is anything I am missing!!

  9. hmi for CP1L

    how to sett up cx programer settings to use hmi/nb5q-tw00b with a CP1L-L14DR-A? and what address do i use for I/O on the hmi?
  10. Hi, I have a project including 32 digital outputs, 8 Pt100 probes, 4 thermocouples, and 4 analog inputs so I have to choose an OMRON PLC. The supplier in my country has only CP2E and CP1E PLCs. Is there a way to connect more than three expansion modules to the PLC? On the website is stated that the maximum number of expansion units is 3, if the answer is no, is there a solution to this problem? Thank you
  11. MX2 Modbus doubt

    Hi there! I'm programming a CP1L-E CPU to control 3 3G3MX2 inverters via Modbus. It got some things right, like the INV002_Refresh_X31 block and its parameters. The thing is, I also want to read some parameters from the inverter using the INV206_ReadParameter block. My doubt is, do I need to be careful so both blocks don't execute at the same time and use the serial port at the same time? Is it better to use one INV206_ReadParameter block for each parameter I want to read? Thanks in advance!
  12. mx2 control with modbus

    Hi all im back to trying to get my inverter to work but this time with modbus, from this post and im stumped, im sure its just one thing somewhere messing it up i have a cp1l-el20 with a cp1w-cif11 and a 3g3mx2 inverter and am attempting to control it via modbus, it is wired up as follows, sp+ to RDB+, sn- to RDA-, common to the plc pin and plc output pin 100.00 to logic input 1. im using 100.00 to put it into run mode the paremeters ive put in are a1=3,a2=1, a4=50, c070=3, c071=5,c072=1, c074=00, c075=1, b27=1. im using MOV to set my speed to d1001 attached is my inv002_refresh x31 fb thanks to any1 who can see my silly mistake

  14. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you
  15. Hello friends, I am an Omron PLC user, but have never used modbus before. I have to connect an Omron CP1L-m to Beckhoff bk7300 via modbus serial gateway. 2-wire RS-485 connection (CP1W-CIF11). I have seen an easy to use Modbus RTU master for CP1L CP1H CJ1 CJ2 CS1 but the examples are not for dual port CP1L-m. If I change the PLC model "CP1HCP1LModbusDualPort" to "CP1L-M", the compiler tells me a lot of warnings about variable types. Is Modbus RTU Master easy to use for CP1L CP1H CJ1 CJ2 CS1 compatible with CP1L-M dual port (port 2)? I have tried to use it but it didn't work, error 02, illegal function code. Somebody could help me? Thank you Enric

  17. VHSC5/C

    Hey all. Wondering if anyone has an example program they'd be willing to share? Specifically I'm using the 1734-VHSC5/C with a 1769-L18ER-BB1B PLC. All of Rockwell's wonderful information only refers to SLC-500 platform. I'm not trying to do anything terribly fancy, just have a quadrature encoder attached to Channels A & B, then using an output to turn on a valve at 8.0" and turn off at 10.0" Any help would be appreciated.
  18. Hi guys! I need some help with a powerflex 525 multi speed configuring. I know I have to set the P046 parameter for 2 “DigIn TrmBlk” (source) and  P047 parameter for 7 which means present frequency. This is the speed reference. I need 3 speed, so I will use Terminal 5 and Terminal 6. When both terminal is zero then 10 Hz, when terminal 5 is 1 but terminal 6 is 0 then 20 Hz and lastly if both terminal is 1 then it will be 30 Hz. I will adjust the speed with the parameters: A410, A411 and A412. Terminal 2 would be the forward and terminal 3 would be the reverse direction. I think these two can be two PLC digital output trough one-one relay. It will be counted the distance by an encoder. When it reach the target the run command will be released and the motor will be stopped with the decel time1. Also I will connect the S1 and S2 for safety.   My question is do I have to connect other wires ? Also do I have to remove the jumper between terminal 11 and 1 ? Am I forget something ? Any comment would be highly appreciated. Thanks ahead.  
  19. hi all, i am tring to program my fx1n on to a bag machine where there is a sensor which checks if the bag length is correct by stopping at the appropriate print also we have given a +5 or -5 to check if the print has moved and if moved to cut the bag from where the signal comes. when the colour sensor is off the plc moves the servo motor the the measure we have given and cuts no problem there but as soon as i give it to check the signal from the colour sensor the plc shows different length when i monitor and also it moves past the print and only stops. it seems its not stopping at the interuption. the colour eye is working we checked. if someone can help it would be greatly appreciated. if you can give a small ladder program which works would be even better :)
  20. Hi, I have found this forum extremely helpful in the past.  I greatly appreciate in advance any help/direction. I am having trouble simply placing/invoking a PRV instruction in CX-Programmer.  The program seems to not recognize really any of the High Speed Counter instructions.  (working with a CT021.  I/O table correct, CJ2H CPU67 PLC rack powered on with all green lights.) Please see attached screenshots for what I mean... the PRV, PRV2, CTBL, SPED, etc instructions just show up red (like they are not understood/recognized PLC instructions/functions) when I try to place in the ladder.  There must be something simple that I am not considering.  Thanks again for any help. Michael
