Hi Everyone,
I am new to the community and i would just like to first say hi. I will be posting alot of questions as i am newer to PLCs and will run into many issues.
My first issue i have run into is a connection issue between my PLC and HMI. I have a nicely programmed machine that was programmed by an engineer and now i need to make changes to it and am running into issues.
The engineer had the Ip address set to 192.168.0.1 for the plc and 192.168.0.2 for the hmi. In the HMI (PanelView Plus 600) settings it was set to detect the plc at this address. I have since expanded our lab and added multiple PLCs that are now all linked together to one computer for programming on the company network. I have set the AB PLC (Micrologix1400) to a static ip address of 10.20.202.3 and had my IT reserve this on their network. I set the HMI to DHCP and told it to point toward the 10.20.202.3 for the PLC connection.
Now here is the main symptoms. When I start up the machien everything works great. I push the start on my HMI and the machine runs. I can see the numbers returned on screen. I will leave the machine running and return in half an hour and the inputs all change to ERROR and i cant control the equipment through the HMI.
Looking for any and all suggestions. I will be sure to pay it forward if i can. Thanks.
