has anyone developed a flow that can count the running hours of a machine using a bit coming from Siemens PLC and emailing the hours in an excel or CSV file on specific time

hi alee, I would recommend to calculate the running hours on the PLC and provide the value to Nodered afterwards. Otherwise you are risking to lose information when connection is disturbed or nodered crashes. I created a flow to collect the running hours from our machines and mail them to people …

Hi nico25, thanks a lot for the suggestion. I have a PC onboard the machine on which I can install Node-Red. PLC is connected with the PC over ethernet so the chances of losing connections with PLC are very low. additionally, if i create an hour meter on PLC the there are two problems; the progra…

alee Perhaps this will work for you. You can convert the ms to whatever time format you desire for the CSV. // NOTE: The time calculations herein are in milliseconds var now = new Date().getTime(); var run_indicator = msg.payload; // Assuming msg.payload input is of type number and 1 means "ON"…

Maybe we should start with your connection problem. what kind of plc do you have and how do you want to connect?

I have s7-400 on old equipment and s7-300 on new equipment connected to PC using Industrial Ethernet

it's working great. but how to continue the counter from the last stopped value? I have used hourglass it works perfectly. the only problem that I have with it is that I want the time from the hourglass in hours and it shows in dd:hh:mm:ss:ms additionally I am want to save the hours in a CSV or Exce…

@nico25 thanks a lot I have tried this but i am getting the fault message "no connection"
