4.4.5 Discrete Output Point Object – Class ID 9 (09
hex
)
The Discrete Output Point Object is used to provide an interface to a subset of the discrete outputs of
the MX. The implementation of this object follows the guidelines of [1] Chapter 5-10.
The Discrete Output Point Object is implemented with 7 instances described in Table 3.1-29, so that
each of the selected discrete outputs of the MX is connected to one instance.
The purpose of this object is to have a SINGLE-BIT access to the relays of the MX via the DeviceNet
network for test and diagnostic purposes.
The Discrete Output Point Object is just another representation of the selected discrete output data in
the Channel Interface Object Instance Attribute 11 (DO_Relay_Chan) see Chapter 3.2.1.2.

5 Instance Attribute 11, Bit 4 DO_Relay_Chan User Output AR-1
6 Instance Attribute 11, Bit 5 DO_Relay_Chan User Output AR-2
7 Instance Attribute 11, Bit 6 DO_Relay_Chan User Output AR-3
4.4.6 Analog Input Point Object – Class ID 10 (0A
hex
)
The Analog Input Point Object is used to provide an interface to a subset of the analog inputs of the MX.
The implementation of this object follows the guidelines of [1] Chapter 5-11.
The Analog Input Point Object is implemented with 2 instances described in Table 3.1-33, so that each
of the selected analog inputs of the MX is connected to one instance.
The purpose of this object is to have a SINGLE access to the generic analog inputs of the MX via the
DeviceNet network for test and diagnostic purposes.
The Analog Input Point Object is just another representation of the selected analog input data in
the Channel Interface Object Instance Attribute 13 (AI_Analog_Input_1_Chan ) and Attribute 14
(AI_Analog_Input_1_Chan) see Chapter 3.2.1.2.

1 Instance Attribute 13 AI_ANALOG_INPUT_1_CHAN
2 Instance Attribute 14 AI_ANALOG_INPUT_2_CHAN
4.4.7 Analog Output Point Object – Class ID 11 (0B
hex
)
The Analog Output Point Object is used to provide an interface to a subset of the analog outputs of the
MX. The implementation of this object follows the guidelines of [1] Chapter 5-12.
The Analog Output Point Object is implemented with 1 instance described in Table 3.1-37, so that each
of the selected analog outputs of the MX is connected to one instance.
The purpose of this object is to have a SINGLE access to the generic analog outputs of the MX via the
DeviceNet network for test and diagnostic purposes.
The Analog Output Point Object is just another representation of the selected analog output data in the
Channel Interface Object Instance Attribute 19 (AO_Analog_Output_Chan) see Chapter 3.2.1.2.
