Hi,

I connect CR1000X and open ComC5 port as RS485 for incoming data of modbus device:

I didnt send any command to this modbus device, it will issue the data every 15min as see in the terminal of logger as below:

Can you recommend the CR1000X instruction for capture these data in the datalogger variable, there are 3 sensors are 2-2, 3-3 and 4-4

Thanks for advise:

 First of all, that data does not look like the Modbus protocol. It appears to be a manufacturer specific ASCII data format.

The first step is reading in a line of data. I recommend SerialInRecord() to get all bytes between line feed from the end of the previous line of data and carriage return at the current line of data.

Public NBytesReturned As Long
Public DataString As String * 64

SerialInRecord (ComC5,DataString,10,0,13,NBytesReturned,11)

 Then, use InStr() to search for your sensor identifier in the beginning of the data string. If it is not the string you are looking for, InStr() returns 0.

The data string will need to be split into separate values. The split option 0(numeric) will probably work. Do take into account that the 32 and numbers from the sensor identifier will appear in the first values of the split results in the array.

Thank you, it wotk out fine.
