Functional test:
– The LED “PS” is illuminated green when the power supply is correctly presented.
– The LEDs “X1” and “X2” illuminate green if a device is connected and the I-Port
communication is ready to function (
è
Chap. 8).
Note
Malfunction due to impermissible cabling
To connect the bus node to the CP string, only use the special CP cables from
Festo (

Basic setting for fieldbus communication
7.1 Removal of the DIL switch cover
To set the DIL switches, the cover must be removed:
1. Switch supply power off.
2. Unscrew the two mounting screws of the transparent cover and remove the
cover.
7.2 Setting the DIL switches
The bus node has two DIL switch groups, each with 6 DIL switches.
When delivered, all DIL switches are set to OFF (
è
Fig. 2).

The maximum address volume of a CP string is 4 bytes for inputs and
4 bytes for outputs (32 inputs and 32 outputs).
7.3 Mounting of the DIL switch cover
1. Place the cover carefully on the bus node. Make sure that the seal is positioned
correctly!
2. Tighten the mounting screws with max. 0.4 Nm using a Torx screwdriver (size
T10) or a corresponding slotted head screwdriver.
The assignment of bus addresses to physical outputs/valves of the con
nected devices can be found in the respective product documentation.

Status display/diagnostics
8.1 Status display via LEDs
PS (power system)
LED
display
Status and significance
LED illuminated green:
– Operating voltage present (within the permissible range).
– Load voltage present (within the permissible range).
LED flashing green:
– Load voltage not present or below the required voltage level.
LED is off:
– Operating voltage not present or below the required voltage level.

X1 – Internal communication between bus node and device 1
LED
display
Status and significance
LED illuminated green:
– Normal operating status
– Device is correctly connected to the bus node.
LED flashing green:
– Connected device reports diagnostics status.
LED illuminated red:
– Device is connected correctly to the bus node, but internal communication is
faulty.
LED flashing red:
– Error in bus module
LED is off:
– No device connected to the bus node.

display
Status and significance
LED illuminated green:
– Normal operating status
– Device is correctly connected to the bus node.
LED flashing green:
– Connected device reports diagnostics status.
LED illuminated red:
– Device is connected correctly to the bus node, but internal communication is
faulty.
LED is off:
– No device connected to the bus node.

display
Status and significance
LED illuminated green:
– Normal operating status, bus connection OK.
LED flashing green:
– Module is not initialised.
– No address volume set (address volume = 0). I.e. DIL switch group 1, DIL switch 1
… 6 and DIL switch group 2, DIL switches 1 and 2 set to OFF.
LED is off:
– No bus connection

8.2 Error diagnostics via CP bus
The bus node supports the 2-byte diagnostics of the CP system.
The bus node does not support switching cycle counters.
