How to reduce the program download time

[Anonimo]

Please we need your help with Slimline CPU if you don’t mind. We are using ethernet communication and the downloading time from LogicLab to the CPU is too long, even when we had a small project in the beggining whith only one or two function, and now with the program getting bigger we have to wait between 3 to 4 minute to download, and it’s very frustrating because each time we had to add something or modify a function we are forced to wait that long, in your opinion is it normal or there is something we’re missing ?

The download time you reported is absolutely too long, I can suggest to you some tricks to reduce the download time.

First of all you must disable the source code download, or if you would that the source code resides on the SlimLine target you can choose to download it only when the LogicLab is disconnected from the SlimLine. To do this please refer to the Project -> Options menu (See screenshot). In the Download tab you can choose when to download the source code.

On PLC application download: Probably is your actual choice, with this choice all times you download the PLC program, you download also the source code and so you waste a lot of time in download it.

Before disconnection: This is the choice to enable if you want to download on the target the source code. With this choice every time you make a modification on the PLC program, you download only it on the target. The source code will be downloaded only when you disconnect the LogicLab from the SlimLine.

Never: With this choice the source code will not be ever downloaded on the SlimLine target.

Another suggestion, to reduce the source code and so the required time to download it on the target (If you choose to download it) is to include in your project only the library objects you use in your program and not all the library. So for example if you use the BLINK FB from the ePLCUtyLib you can import only it from the library insted of attach all the library to the project (See screenshot).
