PLCnext as Time Server

Good morning,
We have a network with an AXC F 1152 and several ILCs. None of them has access to internet.
Is it possible to use the AXC F 1152 as a time server for the ILCs, so all of them have the same time?
Thanks in advance.
Best regards.

The AXC F 1152 runs ntpd, so it should be possible to add entries like this to /etc/ntp.conf:

# Allow LAN machines to synchronize with this ntp server
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
restrict 192.168.2.0 mask 255.255.255.0 nomodify notrap
# You may add as many (or few) CIDR address blocks to allow to synchronize with your machine as you'd like. 

         * This is not specific to PLCnext Control devices, but rather a general ntpd configuration option, so general advice about ntp configuration for any platform should also apply here. Note: it's generally not recommended to manually change system files like this, but you're welcome to try.
         * any changes to this file will be undone by a Type 1 or a Type 2 reset.
         * firmware versions 2025.0 and later will not include ntpd (in case you ever upgrade the firmware).

Hello , I would be interested to understand the reason why FW V > 2025.1 will not include ntpd anymore? Thanks in advance.

Hello. The PLCnext Technology Info Center gives this explanation:
Changes: Miscellaneous PLCnext Technology does not use the std::format due to lacking compiler support and compatibility issues with already present operator << implementations for user-defined types. But PLCnext Technology uses the libfmt code directly, which was now updated to version 10.2.1.

In summary: The functions currently provided by ntpd will be provided by chrony in the future.
