• ibs.outgoing 1: outgoing remote bus is routed (ORB indicator lights up on the
display)

display)
After setting the value with Set Fieldbus Param, the current settings appear under
View.

11.2.1.2 Returning outgoing remote bus configuration using terminating bridge
Alternatively, the ID 40-specific Interbus terminating bridge can be used to
"terminate" the IBS at the last SLK. See Chapter 14 "Overview for ordering ID 40
modules" for terminating bridge ordering information.
The bridge is in the form of an M12 plug and is screwed onto the "Bus Out" contact
(X72). This bridges the outgoing remote bus to the incoming remote bus to close the
IBS loop. This renders configuring via RS232 ineffective and unnecessary.
11.2.2

Configuring the maximum PDU size of the PCP channel

The PDU size determines the number of bytes that can be provided in the PCP
channel. The size configured here is applied with the CMD software for PCP
communication while configuring the Interbus. See also Chapter 8.3.1 "PCP
communication".
The value can be configured from a range of 51 to 242 on the "Fieldbus Settings"
page (see Chapter 11.2.1.1 "Outgoing remote bus configuration using browser").
Enter the value in the Value field. The default value is 240 bytes.
The SLK has to be restarted and the Interbus reconfigured with the CMD tool in
order to apply the new PDU size.
The new settings are retained even after SLK voltage recovery.
