8-2 PDO Mapping
This section gives general information on PDO mapping and specific information on how PDO mapping
is used in Sysmac Studio.
PDO mapping is required to be able to use connected hardware.
Mapping creates a connection between software parts (PDO) and the hardware.
Mapping Inputs and Outputs from the connected hardware makes these Inputs/Outputs usable in the
GRT1-ECT. Mapped Inputs and Outputs can be used as Process Data Objects (PDO) in the
configuration software.
There are six types of I/O that can be connected to the GRT1-ECT:
Digital Outputs (DO), Analog Outputs (AO), Counter Outputs (CO), Digital Inputs (DI), Analog Inputs
(AI) and Counter Inputs (CI).
The GRT1-ECT
can handle up to 512 digital inputs, 512 digital outputs, 64 analog inputs, 64 analog
outputs and 10 counters.
The combination of type and sequence number creates unique PDO names:
The total connected hardware determines the total number of required PDO names.
E.g. For two SmartSlices with each 4 Digital Inputs it is required to map DI001 to DI008.
Additional information
Requirements for mapping:
- Mapping for each type of hardware should start with the first avaible PDOname of that type.
- The mapping should be sequential. It is not allowed to skip PDOnames.
