I’m using Telegraf (v1.25.0) to get data from a modbus device and store the data simultaneously in Influxdb OSS (influxdb2-2.5.1-windows-amd64) and Influxdb Cloud.
Influxdb Cloud Behavior -
When I use data_type=“UFIXED”, for decimal fixed point representation, the Influxdb Cloud shows the message No Data Returned.
When I use data_type=“UINT16”, for the SAME datapoint, the Influxdb Cloud shows the stored data normally, but this representation doesn’t show the decimal fixed point, it only show the integer part of the original value read from Modbus device.
Influxdb Cloud OSS -
When I use both data types, data_type=“UFIXED” or data_type=“UINT16”, Influxdb OSS shows the stored data normally
Could you please, check if telegraf (v1.25.0) data using datatypes data_type=“UFIXED” and data_type=“FIXED” are working correctly with Influxdb Cloud?
Did someone faced this issue?
see below the MODBUS configuration in telegraf.conf:
# Retrieve data from MODBUS slave devices
[[inputs.modbus]]
name = “XXX_modbus”
slave_id = 1
timeout = “2s”
busy_retries = 0
busy_retries_wait = “100ms”
controller = “tcp://192.168.0.240:502”
configuration_type = “register”
holding_registers = [
{ measurement=“mbms_pile”, address=[1240], name=“communication_status”, byte_order = “AB”, data_type=“UINT16”, scale=1.0 },
{ measurement=“mbms_pile”, address=[800], name=“basic_status”, byte_order = “AB”, data_type=“UINT16”, scale=1.0 },
{ measurement=“mbms_pile”, address=[801], name=“protect_info”, byte_order = “AB”, data_type=“UINT16”, scale=1.0 },
{ measurement=“mbms_pile”, address=[802], name=“alarm_info”, byte_order = “AB”, data_type=“UINT16”, scale=1.0 },
{ measurement=“mbms_pile”, address=[803], name=“bat_volt(V)”, byte_order = “AB”, data_type=“UFIXED”, scale=0.1 },
]
