Yes, there are different ways to create Modbus connections. Your version in the LSC file will be the better one in my opinion, but this depends on the understanding of the user. If you need more signals, then you can transfer them in one block. You also need no network inputs NIx to set outputs Qx, just use the right coil number for the outputs. But then you don't have to connect the left side of the output in the diagram. If you need local and remote change, then use an OR block with e.g. a button and a network input to switch an output. See attachment for a Modbus chart of the Logo. Depend on your PC you need the numbers beginning with 0 or 1. You can set it in the Excel sheet. If possible for your PC programmer it would be better to use the Logo as server=slave and the PC as client=master. Then in the Logo program is nothing else to do as to activate the slave. In the Logo program use for digital signals Vx.y or Mx and for analog signal VWx or AMx. These signals are selectable for the PC client very easy.

You has to activate the Modbus server in the Logo and if you want, additional the IP address of your PC to restrict access only with this PC and no other network partner for more safety. See example in attachment with some comments. Regards, Scorp AttachmentModbusServer.zip (169 Downloads) |
