You have a table of registers from the manufacturer Logo! Status of inputs and outputs. Plus, the other registers you create yourself in the program Logo! Please see the following capture form the PLC programming application. The trouble starts if I try and send command 1 which is to enable Q1 nothing happens, if I send command 2 it will enable Q2 not problem. The next issue I also cannot enable the network input NI1, send command 3 and nothing happens. Any assistance would be great!

Q1 may not be enabled due to overwriting in the program. Now there is no Logo at hand! Soft Comfort to understand. As for the lack of response to the NI1 input, a possible problem is that the Communicator sends to the double device,and the input user variables you have are word. The formula for rearranging the bytes before sending the command. In response, the device says that it has included the network variable NI1, so most likely at the program level it is not included.

According to the communication line log, the device understands your command. Nothing happens because of a device logic. You should check that you specify the correct address and value of the commands. Does the manufacturer provide an utility application that can send the required commands to compare data packages? I am not aware of any utilities, I did find another manual that goes into more detail about network connections using modbus.

You may contact the Logo support, provide them communication log and ask for explanation about the device behaviour. Would you mind collaborating with me via email so i can learn how you configured your software please? Can you please share some screenshots of your PLC setup Network project and settings, as well as your rapid scada settings? It would be much appreciated! I will send a compilation of screenshots of all my settings, on the scada and on the PLC.

Will send them in the morning.Note: You are seeing this text-only version of our site because you are using an older browser that is not standards-compliant. How to upgrade to a FREE standards-compliant browser.

I am setting up a sinlge logo at the moment for a startert. The intention, later, is to make a comple switchboard with multiple LOGO's in eacht starter. Now comes the difficult part. I have connected the LOGO to a switch into a small network with my laptop. I have succesfully put a analog value on a flag using VM and was able to read the vaule.

Modbus setting was port not as already mentioned here in the forum. Slave adress does not seem to matter. I can change at random, read is still present. I found the LOGO modbus mapping not quite correct. Output coils start at for correct mapping.

Also the holding register seems to be off. QModMaster is a client and communicates with slaves, but the Logo network connection also is a client, this will not work. Maybe i can send you an example later. Look to the attachment for a Modbus implemenation table as Excel file. You can select the registers with offset 0 or 1 depend on needs.

If you want to set an output Q1 directly, than don't connect the input of Q1 and use the right mapping number of the excel file. By the way the Modbus port normally is and works fine, if the connections are made in the right way. See attachment for a selfmade client on Windows PC and a little servr example for a Logo.

Unpack the zip anywhere in a directory, inside you will find micro client. Micro Server. If the program seems to hang after first start, then wait several seconds, it is okay. Then change ip-address settings to your Logo and start address to for Q1 or for M1.

With the switch you select low or high signal, with the button you send the settings. Q1 or M1 will remain in the last state, until you send an other signal or after shutdown of the Logo.
