7.2.2 Slow Sequence Program Instructions
Use of the slow sequence program instructions should be considered if the
CS225 measurement will exceed the program scan interval of the additional
instruments included in the station. For example, if a CS225 consists of 17 or
more temperature sensors, the time required to poll all sensors and receive data
back can be greater than 5 seconds based on the 300 ms execution time for the
“aR0!” command. For more details on the use of the Slow Sequence program
instructions please reference the related LoggerNet help or relevant datalogger
manual.
7.2.2.1 CR1000 Program to Read the Meta Data of 15 Sensors Daily
In this example a single CS225 is being polled on Control Port 1 of a CR1000
in a slow sequence. The CS225 includes 20 sensors with SDI-12 addresses 1
through 20. Each sensor is polled with the “aR0!” command every 60 seconds,
and stored to a data table on the same interval. Other common station data is
measured every 5 seconds and stored to a daily and hourly data tables.
