Hi Leonardo, I haven’t, but we might be able to help with the installation of the WS EMS on a PLCnext Control, if that is what you are having problems with. If so:

                                             * Which PLC are you using?
                                             * Which package have you tried to install? My first guess is that, for an AXC F 1152 or AXC F 2152, you should try the arm-hwfpu version _without_ the ssl packages, since SSL is already included with the PLCnext firmware.
                                             * Does the wsems run after installation?
                                             * If not, what is the result of the "file" command on the wsems executable?

Hi Martin, Thanks to return, see bellow our considerations:

                                             * Which PLC are you using? 
                                               * AXC F 2152
                                             * Which package have you tried to install? My first guess is that, for an AXC F 1152 or AXC F 2152, you should try the arm-hwfpu version  _without_ the ssl packages, since SSL is already included with the PLCnext firmware. 
                                               * That´s right, but the package avaliable is with SSL, see attached file.
                                             * Does the wsems run after installation? 
                                               * NO.
                                             * If not, what is the result of the "file" command on the wsems executable? 
                                               * "cannot execute binary file"

Hi Leonardo,

Which package have you tried to install? My first guess is that, for an AXC F 1152 or AXC F 2152, you should try the arm-hwfpu version without the ssl packages, since SSL is already included with the PLCnext firmware.
That´s right, but the package avaliable is with SSL, see attached file.

OK, you might have problems using SSL. The OpenSSL version on the AXC F 2152 is 1.1.1d, which might not be compatible with that version of WS EMS. Also, the documentation says that OpenSSL will not work on Linux platforms. 2020 07 21 8 05 22

If not, what is the result of the “file” command on the wsems executable?
“cannot execute binary file”

I am interested in what happens when you pass the name of the wsems executable to the “file” command on the PLC. For example, here is the result when an executable called “2048” is passed to the “file” command: 2020 07 21 8 03 20 You might also consider running WS EMS in a container. The AXC F 2152 includes Balena Engine, which could be used to run docker images that include WS EMS. ~ Martin.
