Inversed ModulesAn analyze of sectors that have been changed (the function COS - CHANGE OF STATE) is done in inverse order:

bit 0 LSB - modules 0..7,
bit 1 - modules 8..15, ...

AHOST
Alternative Path Host(s) 1, 2The configuration of so-called alternative communication path.
It is IP address, hostname or several IP addresses/hosts separated by commas or semicolon. The total number of alternate communication paths entered under these parameters is 12.
Empty value means than an alternative path is not used.

Alternative Path Use TimeoutAfter the elapse of the defined time since the start of using alternative communication path, the viability of communication through standard path is tested again according to the communication line configuration.
Value 0 turns off the testing (communication uses an alternative path while it works).
Note: The parameter value also changes the order of trying the alternative communication paths in case of their malfunction. If the value is nonzero, the standard communication path is always tried after an alternate communication path. If the value is zero, then all alternative communication paths are tried first and only then the standard communication path.

The value reading of the modules. It optimizes the reading of the configured (configured only!) adjacent modules en bloc until completing of MODULE_CNT by one datagram.
