Limitorque MX DeviceNet Field Unit FCD LMENIM2328-00 – 11/05
32
NOTE 1: At boot time of the DeviceNet Limitorque Interface the values stored in non-volatile memory
are used. The SMT Main Board could at any time send new values via SPI.
The other instance attributes do not have any external interfaces, these values are managed in the
protocol stack of the DeviceNet Slave Software.
The further optional attribute Quick Connect (Attribute ID 10) is not supported by DeviceNet Limitorque
Interface.
4.4.4 Discrete Input Point Object – Class ID 8 (08
hex
)
The Discrete Input Point Object is used to provide an interface to a subset of the discrete inputs of the
MX.The Discrete Input Point Object is implemented with 15 instances described in Table 3.1-25, so that
each of the selected discrete inputs of the MX is connected to one instance.
The purpose of this object is to have a SINGLE-BIT access to the discrete inputs from user and to
monitor the state of relay discrete outputs of the MX via the DeviceNet network for test and diagnostic
purposes.
The Discrete Input Point Object is just another representation of the selected discrete input data in the
Channel Interface Object Instance Attribute 7 (DI_Disc_User_Input_Chan) and Attribute 8 (DI_Read_
Disc_Output_Chan) see Chapter 3.2.1.2.
