The trigger field is optional.
•
If it is not present, the poll is always performed.
•
If it is present, a value of 1 triggers the poll.
•
Once all processing of the message has occurred, the trigger value resets to 0.
From a timing perspective, the poll delay for any triggered messages is
included in the overall loop time (even if the trigger value is not set to 1, that
is, not triggered). When the trigger value is set to 1, after one complete loop
period, the triggered message is sent. Then, after one poll delay period,
non-triggered messages continue.

9.3 Config File Slave N Section
Each slave to which the master communicates requires a slave data block. The block
starts with the command:
[SLAVE ADDRESS <N>]
<N> can be any valid Modbus slave address value (from 1 to 255).
Following this statement is the data map for the slave.
