Modbus Master Poll Timeout: Sets the amount of time the F3400/F1000 waits for a response
from the Slave device before moving on to read the next register. It is normally set to the default
of 1. It is adjustable from 1 to 10 seconds.
Modbus Master Poll Interval: Sets the amount of time from when a response is received from
a Slave to when the F3400/F1000 will ask for the next register and is adjustable from 250 to
2000ms. It is normally left at the 250ms default. The interval affects the overall scan rate. If the
F3400/F1000 is configured to read 60 Modbus variables and the poll interval is set to 1000ms
(1second), each Modbus variable will be read approximately once per minute.
Modbus Master Retry Attempts: Determines how many times the F3400/F1000 will request
the same register when there is no response from the Slave before moving on to read the next
register. It is normally left at the default of 1 second and is adjustable from 1 to 99.
