Hi Peter.
Thank you for the reply.
This is the read_server code:
import socket
from pymongo import MongoClient
#import datetime
import sys
# Connection to server (PLC) on port 27017
host = "10.52.124.135"
port = 27017
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
sys.stdout.write(s.recv(1024))
And the write_db code:
from pymongo import MongoClient
import datetime
import socket
import sys
client = MongoClient('mongodb://localhost:27017/')
db = client.test_database
mongodoc = { "data": 'data', "date" : datetime.datetime.utcnow() }
values = db.values
values_id = values.insert_one(mongodoc).inserted_id
So, both these scripts work independently. While, read_server shows the output
of the actual data from PLC, write_db inserts the sample data into the MongoDB.
I am not sure as to how to combine these both and get the desired output.
