Yes, in your case this is normal. You have created two connections manually, so 2 connections are already occupied. Now you have also connect to 2 Modbus devices using drag & drop. With Drag & Drop, own connections created by the software are used. Are 2 connections again, so a total of 4. The maximum number you can read in the manual, see attachment.

The manually created connections are designed so that you can also map inputs and outputs via them. |

Then I'm probably missing something obvious... I'm using this example to read holding registers, convert float to int, etc. In the example memory variable is used to feed F/I function block with the input data. Now I want to use the same connection to the same Modbus server for my Network Input and Output. For now I can easily use the same connection to read DI and write Coil [from the Logo], but for reading the HR (like in example) I always get a separate connection. Please advise. |
