Your explanation is really helpful, especially the part about using pulses from the toothed wheel to synchronize the shift register. It gave me a much clearer picture of how the data can be shifted along with the conveyor movement. I also like the idea of using two registers plus an additional sensor to improve accuracy on longer conveyors — that’s a very practical solution . I’ll probably need to adapt it a bit for Omron PLCs, but the core concept is the same. From what I understand, the key is really the trigger pulse so that the data shift stays consistent with the physical position of the parts on the conveyor. Thanks for sharing your real project experience, it gave me some new insights.

Hi everyone, I’m working on a conveyor system using an Omron CP2E PLC. I have several conveyor lines with products. Normally, each line only carries one type of product, but in some cases, mixed products can appear on the same conveyor line. Because of this, I want to build a system that can track the composition of products on each line. My idea is: if one conveyor line can hold up to 10 pieces, I will use registers D100–D109 to map the products. Each register will represent the sequence and type of product. My questions are: - How can I create a program that scans for the first empty register within a specific range, so I can insert the product type into that position? - If I use a FIFO sequence, when a product leaves the conveyor (for example, from D100), how can I reset that register and automatically shift the remaining registers to the left? That’s all my questions. Thanks a lot, I really appreciate any information or advice you can share.

I'am just starting using omron CP series, and my plan is i wanna integrating 2 plc omron CP1E-N40 (with CP1W-CIF41 eternet port) and a CP2E-N20 for communication using ethernet an fins (PLC-PLC). In additional in this system is the CP2E need to read two barcode sensor, the output barcode sensor is RS 232 normaly, but because some factor i'am add an converter RS 232 to eternet. Because off that my plan is using a switch to connected. To built this system i have a lot of question : 1. is it possible to connecting CP1E-N40 (with CP1W-CIF41 eternet port) and a CP2E-N20 using ethernet an fins (PLC-PLC)? 2. can the CP2E read the barcode sensor with the ethernet port? I am really appriciate any information that related to my case, thanks

Ookay thanks for the information Parky

I’m just starting to set up an N:N network configuration between two FX3G PLCs using RS485. However, the system where this will be applied already has an existing program, and many registers are already in use. My question is : Can I manually initialize (select) which registers will be used for N:N communication, as long as I make sure to choose registers that are not already being used in the original program? ThankYou

Wow, that’s really useful information! Now I at least have a clearer picture and confidence that the system I’m working on has the potential to succeed. Later, when I’m in the middle of the implementation process and if I run into any issues, I’ll reach out again. Thank you, Josue Badilo!

My main consideration is the distance between the sensor and the PLC, as well as the fact that the working area is prone to interference. For this reason, using Ethernet-based communication would be more suitable. In addition, having a PLC equipped with an Ethernet port would also be beneficial for future integration with other systems.

Oh, that’s really helpful information! I’ve read a bit of the manual, but I’m still unsure about a few things. Does this module need any additional extensions to work with the FX3G? If I use this module, can it also handle communication functions (replacing the FX3G-485-BD)? It seems like this module is quite rare and not very common in my country. Also, what about the FX3U-ENET-L? Can the FX3U-ENET-L meet my requirements, since it’s more commonly recognized here..

Hi everyone, I’m a beginner in PLC programming and networking, and I need some advice. Here’s my plan for a project, and I’d like to know if it’s possible or if I need to change something : I will connect two FX3G PLCs using FX3G-485-BD modules for communication (RS-485). On one of these PLCs, I will install an FX3U-ENET-ADP Ethernet module. I want to connect two barcode sensors (Ethernet-based) to this Ethernet module through a switch. My questions: Is this configuration possible? Can the FX3U-ENET-ADP module (and PLC) read data directly from Ethernet barcode sensors? If not, what would be the correct approach to achieve this? Any advice, examples, or documentation references would be very helpful. Thank you!
