Hi, I'm having a little trouble connecting to a PLC from my program. I thought my previous post a few months ago fixed it, but apparently it did not do much. Here is my code: And here is the resulting reply from the PLC after converting it to hexadecimal So far, I've narrowed it down to the issue that my program is sending 64 instead of the 18 that was specified by the FINS command. I assume that the received error is due to the fact that the PLC did not receive the correct instructions from my program. The "End" is not sent by the PLC, it is a personal note for me to know where the received message ends. My goal is to simply receive signals from D00 to D68. I imagine that the received string should be in the form of: 00 C0 00 02 01 01 00 01 00 00 01 01 [Response Code] [Data] Can someone help point out where I can start looking for why my program is sending 64 instead of 18? I do think I am messing up something simple here, but I'm not sure where to start. EDIT: To clarify the models, I am connecting over Ethernet to an Omron CP1L-M40EDT with CP1W-CIF41 Thank you in advance!

Hello all this isnt strictly omron/programmer but has anyone used much in the way of pressure transmitters? we have a wika s-11 pressure transmitter on one of our machines installed roughly 7 months ago where the scaling does not seem to be linear, i only started working here around that time so i dont know how it was installed etc. but its a 0-40 bar 4-20mA transmitter connected to an ad081 4000 resolution connected to a cj2m. so the conversion should be nice and easy 100 raw data = 1 bar however it seems to be scaling logarithmicly to me as we checked with a 2 different guages and when they were at 2 bar the transmitter was showing 137 raw data and at 8 bar it was showing 737 raw data and this seems to keep scaling in this fashion as we get to higher bar. is this a common fault on transmitters? is there anything else that could be causing this? how often would you normally expect a transmitter to last? i checked my scaling FB on another transmitter connected to a compressor and it worked correctly so its not the maths used thanks in advance

CJ2M RTD PT100 4-20mA Temperature Measurement and HMI display
Hartech posted a topic in CX-Programmer
Hey, I have a project which one part involves using a RTD PT100 (0-100 Deg.C 4-20mA) connected to a CJ1W AD041 (ATD input card), the PLC is a CJ2M Basically the PLC needs to read the RTD and display the temperature on a Omron HMI (NS10), via Ethernet, Could someone please help me out with a basic example program - to read and convert the RTD - ATD value to store in memory. Your help would be most appreciated. Thanks Richard -
Dear all, Does anyone have a NTXS verion 1.03? I can only find ver 1.04 in the internet. I am having a trouble while replacing NT3S-ST124B-E. The old one is using RS422 Communication. using a 5 cable in pin 1, 4,5,8, and 9. But it can not communicate after i download the old program I uploaded(firmware ver 1.03) to the new unit (firmware ver 1.04). it keep saying com 1 Communication Error. From the manual NTXS software, I discovered that the communication driver supposed to be downloaded together with the firmware. I used this cable RS-232 connection for programming (upload /download) and it works perfectly fine: db 9 Male (NT3S-ST124B-E) to db 9 female (PC) 2 to 2 3 to 3 5,9 jumper to 5 The program i managed to upload using NTXS 1.04 in Win 7 32 bit and sucessfully download to the new NT3S in Win XP 32 bit (tried so many times but it fails on Win 7 32 bit). The program says that the NT3S is connected to CJ1 PLC. The cable used to connect to the old NT3S is using Pin 1,4,5,8,9 which means it should be RS422 (Xtra Drive). I wanted to try using version 1.03 but I can not find it. Regards, Budianto Scanner NT3S.pzm

Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!

hi everyone, im new here. I have a question, how to connect PLC Omron to Node-red (for IIoT)? if PLC Siemens, it has Siemens IOT2020 to connect PLC Siemens to Node-red. Do Omron haveit own iot gateway like Siemens?

Greetings everyone. I'm new here. Hoping to get help to operate the Omron V400-R2 barcode to the Mitsubishi QJ71C24N so that they can communicate the two devices with the correct method. PLC: Mitsubishi: Q03UDVCPU; barcode: Omron V400-R2; serial communication module: QJ71C24N. I use RS 232 communication cable, I have tried using predefined protocol and non protocol procedures but still can't communicate the two devices. I really appreciate your help.

Hi all, I'm looking to try and send data from the SD Card on my OMRON PLC to a flash drive on my Delta HMI - DOP107WV using FTP. So essentially I need to use the HMI as a FTP host. Is this possible? And if not, is there another way of doing this? Thanks, Ibrahim

Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling Tom

Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks

Servo amp R88D-1S wall mount quick disconnect for motors
scotty134 posted a topic in NJ Series / Sysmac Studio
Hello to everyone! Our company is trying to make a quick disconnect for motors that connect tp servo amplifier R88ND-1S. As I know Omron doesn't have any options to do it or make an extension cable. Does anyone tried to cut the cable and make custom connector? If yes, could you share your experience? I'm afraid of having issue with encoder count. Thank you in advance! Scotty. -

Ok so I recently got the Factory i/o software to practice plc programming more in depth. I got it working easily enough with the siemens TIA software and I am now trying to get it to work with the Omron Sysmac Studio software. I am not sure if it is possible or not. I have access to the hardware but I was really hoping to use the simulation like I can in TIA. Any insight would be appreciated on the subject.

Hi all is it possible to use the internal date of a plc in a function block without setting it as an input for the function block? for instance i have some logic to do something inbetween lets say 10:00 and 16:00 o'clock am i able to use those internals bits of the plc where the time is stored without inputting them to the function block and using them internally? thanks

Hello. I'm currently working on a LD-105CT. Is it possible to change the location of the goal, when the robot failed going the specific goal? And is it possible to perform a new task when the robot received an error message/failed going to the goal? Ex: Pick up cart at location A, drives to location B(Location already has a cart in place) and then change goal to location C(which is available) and then release the cart at location C?

Hello there, I am new to OMRON so need some help to communicate two PLC over FINS. Here are the description of the system... (IO Table image is attached) PLC1- CJ2M-CPU33 IP- 10.113.218.34 SUBNET-255.254.0.0 UNIT NO - 00 (set the dial available on the CPU in HEX) NODE - 22 (set the 2 dials available on the CPU in HEX) PLC2- CJ2M-CPU33 IP- 10.113.218.35 SUBNET-255.254.0.0 UNIT NO - 01 (set the dial available on the CPU in HEX) NODE - 23 (set the 2 dials available on the CPU in HEX) Now, what i have to do is to transfer the D100 to D110 from PLC1 to PLC2's D200 to D210 and Transfer the D100 to D110 from PLC2 to PLC1's D200 to 210. I have tried RECV and ECHRD blocks but didn't succeed yet. Two CPU are connected over ethernet via a industrial switch. Can you help me to achieve data transmission please...

Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8 = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000 any help will be greatly appreciated.
