Description of Master Configuration Screen for CPUs 2010/ 2030

About us
At a Glance
The configuration screen allows configuration of the bus parameters as well as the inputs and outputs.
Inputs
The figure below illustrates the inputs configuration area:
To configure the inputs of the bus slaves, it is necessary to indicate the memory areas to which they will be periodically recopied. To define this zone, you must indicate:
Outputs
The figure below illustrates the outputs configuration area:
The fallback information area contains two radio buttons as well, which defines the behaviour of the device when the CPU is in STOP or in HALT:
To configure the outputs, it is necessary to indicate, as for the inputs, the word and bits tables that will contain the values of the bus slave outputs:
NOTE: The word tables and bit tables are found in the PLC internal memory. Any crossover between two areas of each table is prohibited. The bits area for the inputs cannot overlap the bits area for the outputs. The words area for the inputs cannot overlap the words area for the outputs.
WARNING
UNEXPECTED EQUIPMENT OPERATION
In case of a CANopen bus interruption verify the fallback positions of all devices on the bus are as expected. Consult the relevant equipment's documentation for additional information.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Bus Parameters
The figure below illustrates the bus parameters configuration area:
To configure the bus, it is necessary to indicate:
