Installing the MOVI-PLC® advanced DHE41B control card
Assembly / Installation Notes
3.3.4 Connecting the RS485 interface (terminal X34)
You can connect one of the following units to each of the RS485 interfaces COM1/2
(terminal X34).
• DOP11A operator terminal
• MOVIMOT
®
gearmotor with integrated frequency inverter
3.3.5 Connecting the USB interface (terminal X35)
You can connect an engineering PC (→ Sec. 3.8) to the USB interface (in preparation,
terminal X35)
3.3.6 Connecting the Ethernet 1 system bus (terminal X36)
The Ethernet 1 interface (terminal X36) is reserved as a system bus.
• There must not be any potential displacement between the units connected via the
RS485. Take suitable measures to avoid a potential displacement, e.g. by connect-
ing the unit ground connectors using a separate lead.
• Dynamic terminating resistors are installed. Do not connect any external terminat-
ing resistors.
For more information on how to connect the DOP11A operator terminal, refer to the
sections "Installation" and "Pin assignment" in the "DOP11A Operator Terminals"
manual.
