The code is the following. I apologise in advance if ive done something silly. I have imported time as i want to have a delay in my final code

from pymodbus.version import version
from pymodbus.server.sync import StartSerialServer

from pymodbus.device import ModbusDeviceIdentification
from pymodbus.datastore import ModbusSequentialDataBlock, ModbusSparseDataBlock
from pymodbus.datastore import ModbusSlaveContext, ModbusServerContext

from pymodbus.transaction import ModbusRtuFramer, ModbusBinaryFramer
import time
#-----------------------------------------------------------------------------------------------
import logging

from twisted.names import client

FORMAT = ('%(asctime)-15s %(threadName)-15s'
          ' %(levelname)-8s %(module)-15s:%(lineno)-8s %(message)s')
logging.basicConfig(format=FORMAT)
log = logging.getLogger()
log.setLevel(logging.DEBUG)

#-----------------------------------------------------------------------------------------------
def run_server():

    store = ModbusSlaveContext(
        di=ModbusSequentialDataBlock(0, [17] * 100), #adresse, verdi( di = digital inputs)
        co=ModbusSequentialDataBlock(0, [17] * 100), #--_-- (Coils)
        hr=ModbusSequentialDataBlock(0, [17] * 100), #--_-- (Holding registers)
        ir=ModbusSequentialDataBlock(0, [17] * 100)) #--_-- (input registers)

    context = ModbusServerContext(slaves=store, single=True)
#Dette under mås til og måte være fast(slik jeg forstod det) ellers ville du bare få tomme strings

    identity = ModbusDeviceIdentification()
    identity.VendorName = 'Pymodbus'
    identity.ProductCode = 'PM'
    identity.VendorUrl = 'http://github.com/riptideio/pymodbus/'
    identity.ProductName = 'Pymodbus Server'
    identity.ModelName = 'Pymodbus Server'
    identity.MajorMinorRevision = version.short()

    StartSerialServer(context,
                      framer=ModbusRtuFramer,
                      identity=identity,
                      port='COM1',
                      timeout=1,
                      baudrate=9600)

    #if client.connect():
    #    print("det funker bro, u good homie")


run_server()

As I have no access to a modbus master, it is very difficult for me to know if it will work or not. I will happily be guided.

What I want is the code to connect to a master/client trough RTU and send some messages if possible
