multi-module synchronization system, the user will be able to intelligently set the control tables of

different modules, as well as the division of the reference frequency for the required input-output

processes.

Note that for the slave L-502 there is a frequency limitation on the input

CONV_IN - no more than 1.5 MHz. Thus, two or more L-502 slave modules

can be synchronized only at a reference frequency of 1.5 MHz from the master.

Stopping the primary synchronization scheme is done only programmatically and

asynchronously.

The functionality of the secondary synchronization is embedded in the project,

but is not currently implemented. You can find out about the availability of this

functionality
