Setting the DeviceNet Address and Bus Values (continued)
DeviceNet Terminators
The DeviceNet
trunk
must be terminated on both ends for proper operation . When using the RM-89 you have two options .
•The RM-89 has an internal terminating resistor that can be turned on or off with the Bus Term switch shown
in figure 2 .1 .
• An external bus termination resistor can be used .
If the RM-89 is the last device on the DeviceNet network, the bus must be terminated at the RM-89 .
•In large applications, the RM-89 will often attach to the DeviceNet trunk through a T-Port tap and a termination
resistor can be installed on the un-used connector of the tap . If this is done, the termination resistor
must not be turned on inside the RM-89 . This configuration allows you to physically remove the RM-89
from the network without disrupting communications between the other devices
• You also have the option to install a terminator on the Bus Out connector of the RM-89 . See TURCK’s full line
of network media connectivity .
Replacing the Plug
Once the bus switches have been set, the plug must be re-installed and securely tighten in order to maintain the IP rating of
the RM-89 . Use care when installing the plug so that the o-ring that seals against the back cover is not damaged .
Connector Pinouts
The diagram below shows the pinouts of the two
eurofast ®
connectors on the RM-89 resolvers for DeviceNet . These units
have a part number that ends in “M12” . It is possible to order RM-89 units without the Bus Out connector . These units have
a plug installed in place of the connector . Unused connectors must be capped for the unit to retain its IP67 rating . Contact
