Gavazzi EM24 Meters
Purpose
The purpose of this plugin is to collect data from Carlo Gavazzi EM24_E1 Meters.
Usage
This plugin reads the data from Carlo Gavazzi EM24_E1 Meters via serial or TCP (See: https://gavazziautomation.com/images/PIM/MANUALS/ENG/EM24_E1_IM_USE.pdf). Meter data will be collected to the meter
table. By default, it will collect data every 5 minutes, but can collect at a minimum rate of about 0.3 seconds
via TCP. The plugin will make 1
attempt (by default) to read the meter. This plugin relies on the Modbus Ardexa
plugin. The following data will be collected:
Arguments
Arguments are as follows:
endpoint
. This is either a serial device like/dev/ttyS0
or an IP or DNS like192.168.1.15
bus_addresses
. A Modbus address in the range 2-255. This can be a hyphenated list like3-10
or a list like2,5,7,9
--port
. This is an optional parameter used in an Ethernet gateway, and is the TCP port used for the gateway. Default is502
--attempts
. This is an optional parameter, and determines how many times to times to attempt to read an inverter value. Default is1
--delay
. This is the delay in seconds between inverter send and receive commands, AND ifattempts
> 1. Fractions like0.3
can be used. Default is0.05
--stop_on_any_command_fail
. If this is specified, then any Modbus commands that fail will stop all further queries for all bus addresses and attempts.--serial_lock
. If this is set, the program can only be run one at a time (so as not to overload a Modbus device). If the device being queried is a serial device, this will automatically be set to "on". For IP addresses it is optional.--sampling_rate
. If this is defined, and the sampling rate is greater than 1, then all values listed above will be collected as an average. In other words; it will take a sample at the nominated frequency. After X samples defined bysampling_rate
, a record will be written and sent to the cloud.
