Compactlogix 1768-L45

4 posts in this topic

I have been using the 1769-L35E, but have a project with different network requirements. I need two separate ethernet networks and a devicenet network. After looking over the AB site, I am planning on going with a 1768-L45 with 2 1768-ENBT's on the 1768 bus and then a 1769-SDN on the 1769 bus. Does anyone see any issues with this configuration?

My Allen Bradley rep told me to start using the EN2T. It's cheaper and has more CIP connections according to him. Oops... I just saw Compact Logix. I'm not sure what's available for those.

What you have selected is acceptable. You could save some money by selecting the L43. The L45 can have four comms modules on the 1768 bus, while the L43 can have two comms modules on the 1768 bus. If you have no plas for adding a motion controller in the future, then go with the L43.

Thanks for the replies, I selected the L45 because I need more than 16 IO Cards.
