4.4.5Discrete Output Point Object – Class ID 9 (09hex)

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 510.

The Discrete Output Point Object is implemented with 7 instances described in Table 3.129, 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.

4.4.6Analog Input Point Object – Class ID 10 (0Ahex)

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 511.

The Analog Input Point Object is implemented with 2 instances described in Table 3.133, 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.

4.4.7Analog Output Point Object – Class ID 11 (0Bhex)

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 512.

The Analog Output Point Object is implemented with 1 instance described in Table 3.137, 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

33

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.
