PLC interfaces
The IL function block provides a standard interface for access to PLUS functions of the tightening system
for the customer system PLC by means of Profinet I/O signals. The I/O signals are assigned to the
Profinet field bus interface via the PLC table or the
Data IL
function.
Profinet interface - Overview
For communication with the customer system PLC, the Profinet interface with a total of 64 bytes of input
and 64 bytes of output data is used. The various data ranges are configured in the
Set Profinet IO
interface
group.
Make the following settings on the
I/O and data
index card:
•
Number of I points
: 256E (32 bytes)
•
Number of O points:
448A (56 bytes)
•
Receive data:
0
•
Send data
: 0
•
