TLSConnections
This setting controls the number of concurrent TLS (secure or encrypted)
client socket connections that the datalogger will be capable of
handling at any given time. This will affect FTPS and HTTPS services.
This count will be increased by the number of DNP() instructions in the
datalogger's program.
This setting will control the amount of RAM that the datalogger will use
for TLS connections. For every connection, approximately 20KBytes of
RAM will be required. This will affect the amount of memory available
for program and data storage. Changing this setting will force the
datalogger to recompile its program so that it can reallocate memory
