Various questions about SlimLine and RNDIS

[Arkadiusz]

a) Is there a possibility LogicLab FORCE I O, and if you do start and stop the program. For me, these functions are disabled.

b) I have a problem with copying files from PC to SlimLine to the SD card.  I did format the SD card. He used FileZilla FTP client and Total Commander. In both cases, I can copy files from SlimLine  to  PC. I can create and delete files, but I can not copy files from the PC to SlimLine. How to configure FTP client to address it. I found some information on the forum, but it did not help.

c) I have a problem with the installation of the driver RNDIS. When you connect the USB to the SlimLine and PC system (Windows 7 x64 Ultimate) detects the device, but it does not install automatically divera RNDIS. I get the message that the device is damaged and the driver installation is not possible. Finally, in device manager installed as unknown USB device. Attempting to install a new network card and driver from the folder “RndisSetup” not jam up.  Attempting to manually install the driver RNDIS microsoft failed because  in “Microsoft Corporation” I can not find the driver RNDIS.  How to install RNDIS DRIVER in the system. At the moment I can not connect to the USB Slimline, I’m using Ethernet.

The Force I/O bar it’s not managed it’s always disabled, the real I/Os can be forced by copying them to the watch bar. To force them, they must not be managed by the program. This suggestion is valid for all the variables, is not possible to force a variable that is managed by the program. You force it but the program set it’s value according to the logic, overwriting your forcing (View screenshot).

The PLC run time status bar, is enabled on the devices starting from Device ID “Mps046_XTarget_10_0”. All the compact modules are of this type. You probably use a CPU ARM7 module version A, Device ID “Mps046_XTarget_8_0”, on these devices the bar is not enabled. Anyway this bar is not so useful, it allows only to stop and start the PLC running and display the tasks loop times. The tasks loop times is visible by inserting in the watch window the related variables, you can load them from the SystemVariables.wls watch list file. (View screenshot).

It seems that you connect to a CPU ARM7 module by using Ethernet and try to access to it by FTP is it true ? By reading your report it seems that you are able to operate on the SlimLine files only in reading. The problem could be in the file name, it must be long up to 16 characters (Name plus extension).So filenames like MyFile.txt is ok, but ThisIsMyFile.report is not accepted. Another problem could be in the SDCard formatting, when you format the SDCard you define how many files can be stored on it, if you reach the number of defined files, no more files can be stored.

About the RNDIS we have a lot of installations of it on a Windows 7 (32 and 64 bits) and no customer complain problems. I cannot understand why you report problem on it. Have your Windows system up to date ? Have you tried to change the USB cable ? Can you try to connect it on another PC ?

I have forgot to highlight in the previous post that the USB RNDIS driver works only on devices equipped with the firmware SFW184**00. All the compact CPUs and the CPU ARM7 release B are equipped with this firmware. The RNDIS doesn’t work on ARM7 CPU release A.

All CPU modules can be programmed with LogicLab by using a serial connection, so you can programming them even if the RNDIS doesn’t work. It’s obvious that to operate with FTP and to access to the web server it’s necessary to have a TCP/IP connection, so it’s possible only if you use a CPU module with ethernet or if you install the RNDIS driver on USB connection.

The problem with copying files due to a long file names. Files with short names can be copied in both directions with no problem.
