EtherCAT
As with EtherNet/IP, the process data width is fixed and is 445 bytes for input process data and 273 bytes
for output process data, regardless of the actual number of ejectors, DI modules or IO-Link masters of the
compact terminal.
IO-Link Process Data
The IO-Link process data of an IO-Link master port is forwarded to the Ethernet bus system unchanged,
i.e. the endianness (byte order) and structure remain unchanged. The start byte in the overall Ethernet
process data for the respective IO-Link master port is listed in table 5.2.1 as “Master x Port x Input” and
5.2.2 as “Master x Port x Output”.
5.2.2 Input Process Data
The input data provides cyclical reporting of a range of information relating to the SCTSi, the individual
ejectors and the additional modules:
•
Device status of the SCTSi in the form of a status traffic light (refer to the “Device status” parame-
ter)
•
The switching values H1 and H2 of the connected ejectors and their hysteresis h1 and h2
•
Error messages of the bus module
•
Condition monitoring events from the bus module and the individual ejectors
•
Total air consumption
•
Process data of IO-Link devices connected to the IO-Link master ports or the status of the inputs if
the IO-Link master ports are defined as inputs
•
Status of the DI modules
The length of the input process data depends on the design of the compact terminal with respect to the
protocol and number of actual components of the compact terminal (see 5.2 “Process Data”).
