My problem is, there are 6 machine on one production line.... All 6 machines are on same I.P & subnet network i.e 10.1.xx.xx For example, the IP of - 1st Machine PLC OPC server is at is 10.1.31.11 2nd Machine PLC OPC server is at 10.1.32.11 3rd Machine PLC OPC server is at is 10.1.33.11 4th Machine PLC OPC server is at is 10.1.34.11 5th Machine PLC OPC server is at is 10.1.35.11 6th Machine PLC OPC server is at is 10.1.36.11 Now in order to communicate with them, i modify my Laptop's I.P to 10.1.99.xx and with this i successfully communicate will all of them but one by one... I want to know if there is any way to use only 1 IOT device to communicate with OPC servers all above-mentioned PLCs in order to sample all OPC servers at the very same timestamp? If yes, then how?
