We have several dozen PLC5's, some with ethernet cpu's and some with DH+. We have upgraded as convenient the DH+ to ethernet with bridges so they are all on our "Plant PLC" network. We have all the computers on the "Plant Admin" network.
So we are being directed by corp. to install a new piece of equipment and somehow integrate it into the Plant PLC network.
MicroLogix 1100 <--- Ethernet/IP ---> Metler Toledo Scale <--- Admin Network ---> Logging PC
The MicroLogix only has one Ethernet/IP port so we are trying to figure out how to put it on the Plant PLC network so the PLC5's can control flow in/out of the new equipment.
Option 1) MicroLogix1100 <--- Ethernet/IP --> Stratix 5700 Managed Ethernet Switch <-- Plant PLC Network. Then we could plug the Scale controller into the AB Switch and everybody is talking directly.
Option 2) Plant PLC Network --> AB 1761-NET-ENI <---> MicroLogix rs232 port <--- Ethernet/IP ---> Metler Toledo Scale <--- Admin Network ---> Logging PC
I am almost tempted to purchase both options just to guarantee the commission date but wanted to ask and see if anyone has used a switch in this kind of situation.
