    I don't know the drive (variator) that you are working with but typically you could select set speeds by digital inputs (PLC outputs). This would not be incremental / decremental but may get you want you want depending on how many speeds you need.

    Alternatively, to do what I think you are looking for, you would need an analog signal. The analog output module you require would depend on the type of analog input the drive has available.

    In the previous post I attached an example of what I had thought of doing but I don't understand why the plc outputs are either the ones you see on the cpu or the ones on the first output card.

    Both the CQM1-CPU41 and the CJ1M do not have built-in Outputs. So, the output module Word on the CQM1 will be 100. For example, if you are using output 4, the address will be 100.04. The CJ1M will be addressed differently.

    I leave the network I made to see how the counts of pieces per minute and total pieces are done

    I didn't look at the file you provided but I must ask, are these values accurate? Do you have the dimensions of the product? Can you multiply the length * width then multiply by the number of pieces?

    The CIF41 will communicate via FINS. Use the link above for an example. This will work since the CJ2M supports FINS protocol.

    The EIP61will communicate via FINS or EtherNet/IP (Industrial Protocol). This will also work since the CJ2M supports EtherNet/IP but it is not necessary. This would be useful to communicate with a non-Omron PLC that does not support FINS.

    Hello everyone.

    I have a CJ2M and CP1H networked. I need to exchange information between them. Could anyone help me. 

    CJ2M is 192.168.250.1

    CP1H is 192.168.250.2

    I tried via NetConfigurator, but it doesn't recognize the CP1H.

    Network Configurator would be used for EtherNet/IP. The CP1H would need the CP1W-EIP61 installed to communicate EtherNet/IP. 

    Omron's native Ethernet protocol is FINS. This is possible with any of Omron's Ethernet ports.

    Hi, has anyone tried to get a Mitsubishi iQ-R to communicate with the Keyence IV3 series cameras over Ethernet/IP? 

    I have not but I will offer some advice since the forum participation has been quite low lately. I have implemented the IV3 via Omron and Keyence PLCs. I don't have the files with me this weekend. I'll look these up next when I'm at my work PC.

    There are videos about how to use the IV3 with Allen-Bradley (Rockwell) PLCs but Rockwell's implementation of EIP is completely different from Mitsubishi's implementation.

    EtherNet/IP is a standard that is the same for all manufacturers. Break it down to its simplest form and the examples can help you.

    The instruction videos for Allen-Bradley uses the I/O tree to create tags and pre-made AOI's to create the logic to do all of the communication work in the PLC code, which is a process that I am familiar with. However, none of that is relevant to the Mitsubishi PLCs.

    The AOI is synonymous to a Function Block. You do not need this to make the cyclic connection. It will map the Input and Output Bytes to data types that are easy to understand and use. A lot of manufacturers will provide these for Rockwell PLCs since they are the leader in the market. It helps them sell more products.

    I am using an existing system with the RJ71EIP91, I have the IV3 EDS file added to the Ethernet/IP Configuration Toll for RJ71EIP91 software, I know I need to add the IV3, set the IP address and connection number. But how do I access the data, and send the trigger for the IV3?

    I'm sorry I haven't used Mitsubishi software for EIP connections and I haven't used the PLC programming software in a long time. You should be able to find the settings that match the examples they have for KV and Rockwell PLCs. Somewhere in the configuration it may refer to Tag Sets. The Tag Sets may contain an address that you provide. The addresses you use will be the Input and Output data that you access. Referencing the Field Network manual, it will be similar to the KV settings section, step 4. The commenting in the KV series is somewhat automatic for obvious reasons. 

    The most important thing about getting any EIP device connected, is getting the Input and Output data sizes correct for the specified Assembly Instance. Referencing the screenshot below, if your Input is D100 then your input data will be D100 through D196. They maybe start at D200 for Output (D200 through D205).

    That is not an Omron product and I haven't used one of those in quite some time. Assuming you want to connect to an Omron PLC (C series, CP/CJ) then you'll need to see if the HMI supports Omron FINS protocol for an Ethernet connection. Connecting multiple HMIs shouldn't be problem as long as each device has a unique IP address. FINS node will be the last octet in the IP address. No PLC setup should be necessary. You'll just need to know the IP / FINS node.

    Note, you may see a Host Link protocol available. This is for RS232C/RS422 connections.

    In my opinion, Keyence has always struggled with field bus and are usually late to the game. I will also note that Keyence measurement products perform exceptionally well.... just the fieldbus can be a pain.

    in EtherCat network, nodes are daisy chained. branches are possible but there are limitations and this requires hardware that supports this.

    In Sysmac Studio the EtherCat configuration screen shows a diagram of all this very clearly, including the couplers and its branches. This is one of my favorite features in the software. In all of our distribution and configuration with today's technology, Omron makes EtherCat very simple. Getting compliant ESI files has been my only struggle.

    Your suspicions are correct concerning the right-side end cover. This is required to terminate the I/O bus. I don't believe the missing modules are an issue since the CQM1H does not have an I/O table. 

    When you turned on DIP SW 5, the serial port settings change to Omron default (9600, 7, E, 2). If you double click the settings in the project tree, look under the Host Link Port tab. You'll see they are probably different. When you downloaded the program you changed the serial settings and lost connection. If you need (or wish) to use the downloaded settings with DIP SW 5 OFF, then double click the PLC in the project tree, click Settings under Network Type, Driver tab, then change this to match the new settings.

    Perform a cross reference or search for DM6645 in the program to make sure it is not being written to in the program. This was the method of setting up the ports before CX Programmer come along. All DM memory is retentive so something is writing to it. Maybe the switch is defective?

    The correct procedure using CX Programmer is to make the change in the Settings dialog, then cycle power to the PLC.

    OK, I tried this and it does ask for a serial number. I would call tech support and see if they can get you a download. 

    Alternatively, the manual shows you can program it with the panel keyboard.

    Ultimately, I would search out a newer panel. What is it connected to?
