CONFIGURATION
One of the many advantages of Fieldbus is that device configuration is independent of the
configuration tool. The
DC302 may be configured by a third party terminal or operator console.
The DC302 has several Function Blocks built in, such as Flip-Flop and Edge Trigger, Analog Alarm,
Timer and Logic, Discrete Input, Discrete Output, Multiple Discrete Input, Multiple, Discrete Output,
Arithmetic, Input Select, PID controller, PID Step and Flexible Function Block.
Function Blocks are not covered in this manual. For explanation and details of function blocks, see
the
Function Blocks Manual.
The DC302 can share its Function Blocks with other connected devices using the SYSCON.
For explanation and details for using SYSCON, please see the SYSCON Manual.
NOTE
(1) Do not use DIs together with MDIs and DOs together with MDO blocks.
(2) Do not instantiate FFB block together with MDI, this causes channel conflict.
(3) From the serial number 2000 the DC302 comes with 8 DI blocks and 8 DO blocks already instantiated.
The firmware version of the equipment must be used with the corresponding version of
DD/CFF.

Connecting physical signals to Digital Input Block
The DI block takes the discrete input data, selected by channel number, and makes it available to
other function blocks at its output.
For details, please see the Function Block Manual.
