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.

Hi everyone! I got this machine with a CP1H PLC and NS8-TV00B-V2 as PT. I was told that they were working fine, but suddenly, It appeared a communication issue: black screen and "connecting..." at right bottom. I dont know if It is a configuration problem or some hardware damage. These are the configuration in the PT and the PLC. The communication is through RS232 Serial. I tried to communicate another PT screen with the same communication settings and IT WORKED!. ' I've been thinking that, perhaps, the serial port A is damaged, I have tried to set port b, but I havent could. How can I configurate PORT B?? THANKS...

Behavior of variables read by Prosoft MVI56-MNETR in case of network failure
marcelosb posted a topic in Allen Bradley / Rockwell Automation
Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help! -

ControlLogix L71 controller and Citect SCADA 7.10 Communication
DeeEngr posted a topic in HMI & SCADA
Hi All, Hope you all doing well in this pandemic life. I would need your expertise with an issue I have been struggling with for past few days and thought to reach out here. I am working on a migration project with GE PLC and Citect SCADA 7.10. The GE PLC is migrated to ControlLogix L74 Rev24.10 while Citect SCADA is retained. For testing I only have L71 and L82 and could not managed to organise L74. When the code the loaded in L71 and connected to Citect, I cannot see tags in Graphic page but I see the subscription.txt in Debug folder shows all tags good . The same code when loaded in L82, the Citect works instantly. Does anyone know this behaviour of PLC and SCADA? Regards, DeeEngr -
Weintek HMI Modbus Communication With Siemens Energy Meter PAC3200
Junaid Abbas posted a topic in HMI & SCADA
i am trying to communication my weintek HMI with Siemens Energy Meter PAC3200. I am using MODBUS TCP/IP Protocol but i am unable to read the data register of my energy meter. Somehow i got to read the 32bit data register but still unable to read the 64bit data register of my total KWHr Energy consumption. I have also attached the manual of my energy meter. Please guide how to read all the data registers of that energy meter. Please see the page 40 onwards for reference. The manual the about 7MB so i cannot attach the file. https://support.industry.siemens.com/cs/attachments/26504150/A5E01168664B-04_EN-US_122016_201612221316360495.pdf -

Hi everyone, first time posting here. I've got a problem with the Modbus MTCP-CP1L-Server fonction block. it worked fine for a good amount of time until i try to change an ethernet switch (not managed) on my network. at this moment the fonction block started to give me an error code (2211 ''unit is busy, can't execute''). So i put the old switch back again and I called Omron and they tell me to download Etherway and try to send some data to it but they can't do more. I did and BAM, it worked again. everything was fine for about a week and i was like, okay if etherway can ''solve my problem with the fonction block, i can put the new switch again, No I can't. It give me the same error, I try'd so many thing( put the old switch, everything that was possible in Etherway, change IP address, ethernet setting, reboot everything, connecting the unit direct to my PC. nothing can erase that error. Unit is an CP1L-EM with built-in Ethernet port did someone had have the same problem, or have any idea that can help me ? thank. Sorry for my poor English, its not my first language.

I requested support on getting my DVP to talk to Factory IO for some cost-effective programming experience but the DVP is really poorly documented. The below wording and 2 pictures were all the support I got as I am not a business. The M codes are not listed in the ISPSoft help file and hard to track down, combined with things like "After the reception of the command is complete, bit8 in D1395 is ON" and then if I am reading input registers and holding coils but saving to a D word register how the heck do I convert the data into a useable boolean format for logic use??!! I have no been able to even get the DVP to read or write ANYTHING but I can use a modbus program to turn on the DVP's bits no problem so I know communication works. eg: F05 H500 will toggle coil Y0. The issue is when I try and use the DVP as the modbus client. From my laptop I can use these commands to modify Factory IO which is running as modbus server Slave ID 1: F02 H0000 H0009 (Read inputs 0 to 9) Tx: 00 02 00 00 00 06 01 02 00 00 00 0A, Rx: 00 02 00 00 00 05 01 02 02 C0 00 (In put 6 & 7 are on) F15 H0000 H0009 (force coils 0 to 9) Tx: 00 0F 00 00 00 09 01 0F 00 00 00 0A 02 00 00, Rx: 00 0F 00 00 00 06 01 0F 00 00 00 0A But how the heck do I format the LD program to actually do those commands?

I am using OMRON CJ2M-CPU15 with SCU41-V1 communication module I want to establish communication (rs485 modbus) between omron and Schneider device for reading out electrical parameters. How I can do this? I could not find any manuals and this is becoming very hard for me. I want simply to read few registers from Schneider. Where do I set unit number, starting register, ending register, number of data? I was recently using Siemens and Unitronix and started working with Omron recenlty. Do you have any examples or manuals for this? Thanks in advance
