The watchdog condition can also be activate, where after the communication loss detection for
the slave device with the master, the equipment can change to a fail-safe condition.
The
DC303
also has the Empty module for application where is not necessary all function blocks.
There is an order for cyclic communication as follow:
DO_1, DO_2,…DO_8, DI_, DI_2, …DI_16.
For example, where is necessary to work only with DOs blocks, we have:
DO_1, DO_2, DO_3, DO_4, DO_5, DO6, DO_7, DO_8, EMPTY_MODULE, EMPTY_MODULE,
EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE,
EMPTY_MODULE.
Suppose now the application will work with DOs blocks and only DI2:
DO_1,
DO_2,
DO_3,
DO_4,
DO_5,
DO6,
DO_7,
DO_8, EMPTY_MODULE, DI_2,
EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE,
EMPTY_MODULE.
If the DO blocks are in AUTO, then the device will receive the value and status of the discrete
setpoint of the class 1 master and the user will also be able to write in this value via class 2 master.
In this case, the setpoint status should always be equal to 0x80 (“good") and the following
configurations can be chosen:
• SP_D
• SP_D+RB_D
• SP_D+RB_D+CB_D
If the DO blocks are in RCAS, then the device will receive the value and status of the discrete
setpoint only via class 1 master. In this case, the setpoint status should always be equal to 0xc4
(“IA"). The following configurations can be chosen:
• SP_D
• SP_D+RB_D
• SP_D+RB_D+CB_D
• RIN_D+ROUT_D
• RIN_D+CB_D
• SP_D+RB_D+RIN_D+CB_D
