What is the 1785-L40B/E？

The Allen-Bradley 1785-L40B/E is a discontinued PLC-5/40 programmable logic controller (PLC) processor module, combining the features of the L40B (no Ethernet) and L40E (with Ethernet) models.

What is the main difference between the 1785-L40B and 1785-L40E?

The primary difference is the communication ports. The 1785-L40B does not have an integrated Ethernet port, while the 1785-L40E (and thus the combined B/E part number) includes one built-in Ethernet port in addition to other channels.

How do I troubleshoot communication with the 1785-L40E?

You can establish communication using software like RSLinx Classic Light via the RS-232 port. Use the auto-configure feature to set the correct communication parameters. For Ethernet troubleshooting, configure a static IP address in RSLogix 5 software and use the command prompt to ping the address.
