I understand, I have already made the corrections, with respect to the program, I have not yet developed more of the logic hoping to resolve the question about how to read the variables from a Gateway, or with that configuration the PLC remains open to be read from the master, and that's it Is it up to this Master to choose which variables to read from the PLC?

Hello, thank you all for your answers, to describe a little more about my application, through the JZ20-J-R31 PLC (in charge of managing some motors and having some variables with the status of each motor that it commands) together with the card ethernet mj20 et1 I want to connect with a gateway through the Modbus TCP protocol to pass the data of the status variables and monitor the status of the motors online, in the cloud (very similar to a scada but on a smaller scale and more simple without control, only monitoring), so my question is, the PLC would work as a Slave and the gateway as a master, if I want to read the marks from M20-to M50, can I select somewhere this range of variables so that I can do it? read from the gateway, or would it depend on the gateway's configuration to read the variables I need. Thank you I hope I have been clear with my application, I have attached the configuration I have so far.

Ready I understand this, but how can I select which variables I can read, in other software there are tables where the variables I need are added, in u90 ladder I did not see this tool, are the marks that I have using automatically passed? thank you.

Good afternoon, I have a concern, I have some variables that I need to send from an mj20 et1 PLC, I am using the U90 ladder software, the question that is going to monitor all the variables contained in the program, but for this I need to send the states of the variables to a gateway through the Ethernet card,(It should be noted that I have the mj20 et1 module), I wanted to ask if there is a way to make a table with the variables that I want to send or if there is another way, Thank you.
