Planned restart is also not possible. This feature has routers for several dollars. It collapses in such detail as that it fills the SIM card with the received SMS and stops receiving further sms. I do not recommend you to use problems only. FrantaM

We suspect that if the public IP is changed, it will not be routed to DynDNS. Does anyone else know the problem or a solution? Best regards Dani

The bigger problem is to delete received SMS which module will not overfill and will be stored on the card and it will fill up time and stops accepting new SMS. Frantam

The problem with SMS is really unthinkable firmware. Shoring the number of saved SMS on the card is really an error! for a company such as Siemens is really surprising. I have quite a lot of installation problems with it. Frantam

We have discussed the issue internaly with the product management and this is the result: Productmanagement The described issue sounds like a topic, which should be solved meanwhile with the FW-Update V2.1. LOGO! CMR could be updated easily be every customer and for free. Please check this Document published within the Product Support pages: Firmware update V2.1 for LOGO! CMR2020 (6GK7142-7BX00-0AX0) and LOGO! CMR2040 (6GK7142-7EX00-0AX0) Your feedback would be very welcome. Best regards, Jen_Moderator
