Example for process data (mapping)
Description of the process data
Further information on the process data (mapping) for any EtherCAT Terminal can be found in the
corresponding documentation. For example, for the EL3062 under:
Commissioning > Process
data and operation modes> Process data.
The EL3062 EtherCAT Terminal mentioned above offers two different process data per analog channel for
transfer. The analog value
Value (16-bit)
and status information
Status (16-bit)
. The total for the two analog
channels is therefore 64 bits or 8 bytes.
There is a choice of two types of process data in the EL3062:
•
Standard:
standard setting, Value (16 bit) and status information (8 or 16 bit) are transmitted per
channel.
•
Compact:
only the Value (16 bit) is transmitted per channel.
To obtain a description of the individual bits, add the EtherCAT Terminal to TwinCAT, irrespective of your
PROFIBUS configuration, or read the corresponding documentation
Fig. 28: Meaning of the individual bits with all subvariables and structure contents for the EL3062.
Status word
The status word (SW) is located in the input process image, and is transmitted from terminal to the controller.
