i_am_mrp (Customer) asked a question.
Do more designer requires connection to PLC to do HTTPCMD? Why is this a restriction? For example you have the SNTP client which seems to run from the Do-more/Sim. If there is some config to enable let me know, else it would be great feature.
There is no requirement for the PLC to be connected to Do-more Designer. Check your PLC IP setup and make sure that you have a gateway set in the PLC.
