1. 24 VDC, 18 W at the 15 pole Sub-D connector for the transmitter itself;
2. 24 VDC nominal, <2 W range (+11 … +25 V) at the DeviceNet micro style
connector for the DeviceNet transceiver.

dark Device is not online.
•The device has not completed the Duplicate
MAC_ID test yet.
•The device may not be powered, look at Module

connected flashing green Device is online but has no connections in the estab- lished state.
•The device has passed the Dup_MAC_ID test, is
online, but has no established connections to other
nodes.
•The device is not allocated to a master.

failure red Failed communication device. The device has detected an error that has rendered it incapable of communicat-
ing on the network (Duplicate MAC ID, or Bus–off).
The status of the dual filament hot cathode is indicated by a LED on top of the
transmitter.

During device initialization, the node address switches are read by the device firm-
ware. If the switches specify a valid DeviceNet MAC ID, i.e. a value from 0 … 63,
this value is used as the device MAC ID. If the specified MAC ID differs from the
value stored in the device’s non-volatile RAM (NVRAM), the new MAC ID will be
saved in NVRAM. If the switches specify an invalid DeviceNet MAC ID, i.e. a value
greater than 63, the current value stored in the device’s NVRAM is used as the
device MAC ID.
A single, rotary switch is provided for configuring the data rate of the device. The
switch has three valid positions for the DeviceNet data rates, 125, 250, and
500 kBaud, where the position 1 is equal to 125 kBaud, 2 equal 250 kBaud and 5
equal 500 kBaud. All remaining switch positions specify software selection of the
data rate.
The device has two setpoint relays (Setpoint A and Setpoint B). The setpoints of
these relays are adjustable only by two potentiometers (marked SETPOINT A and
SETPOINT B).
The relay contacts are available at the 15-pin D-Sub connector.

2 Object Structure
2.1 Connection Object
Class Code 05h= 05d
The connection class allocates and manages the internal resources associated
with both I/O and explicit messaging connections. The specific instance generated
by the connection class is referred to as a connection instance or a connection
object.
The following instances of the connection object are supported:
•Instance 1: Explicit Messaging
•Instance 2: I/O-Polling
Please refer to the DeviceNet specification for further information.
2.1.1 Vendor-Specific Object Extension on Instance 2 Poll
Connection
For the selection of the active input assembly the following vendor specific attribute
can be used.
Vendor specific extension:

100 Optional Get/

USINT Contains the In-
stance number of
the assembly used
by this connection
to send data
1, 2, 4, 5,
8, 9, 10,
12, 13
This vendor-specific attribute facilitates the configuration of the data assembly, sent
by the ITR 200 SD to the DeviceNet Master as Poll response. It offers the possibi-
lity to select a (predefined) data assembly via a configuration tool and the EDS file
→[5]. Attribute 100 allows the user to configure the Poll I/O Data Assembly via
EDS even when the Poll Connection of the ITR 200 SD is in the established state.
The Assembly Number is stored non volatile. Modifications of the Poll Produce
Assembly Instance will take effect only after a reset of the ITR 200 SD.
Thus, definition of the ITR 200 SD data assembly can be done in two ways:
1. Standard methode (without using attribute 100):
The DeviceNet Master configures the "Produced Connection Path” Attribute of
the Poll connection (Connection Instance 2) when establishing communication
to the ITR 200 SD. This requires a Master to support expanded explicit mes-
saging capabilities.
2. Directly setting Attribute 100 e.g. by a configuration tool
(e.g. RS Networks) + Device Reset.
