LOGO! CMR2040:

Time synchronization via GPS: Affects all systems connected with a LOGO! CMR2040 update the assembly time via GPS. Due to the overflow of a counter in the GPS receiver (GPS rollover), there will be incorrect GPS time synchronization from 2 November 2019 at 23:59:42 UTC with older firmware versions. Upgrading to FW V2.1.7 is strongly recommended for this application.

The CMR2020 is not affected.

Communication via VPN: The data throughput via the VPN connection of the LOGO! CMR2040 has been increased.

SMS transmission: The sporadic behavior that after upgrading the FW from V1.x to V2.x no SMS could be sent has been fixed.

LOGO! CMR2020 and LOGO! CMR 2040:

SMS user group: The behavior that SMS messages were incorrectly sent to user groups 1 and 2 instead of user groups 9 and 10 has been fixed.

Name resolution (DNS): The name resolution for time synchronization via NTP, DynDNS and e-mail has been improved.
