“Operating mode” parameter
The “Operation mode” parameter defines the function of the
respective IO-Link port (C/Q, L+ and L- connections). The
parameter does not influence the function of the additional
digital input (DI connection).
Disabled (default)
The supply voltage at L+ and communication via C/Q are
disabled.
DO
The C/Q connection works as a digital output. The length of
the process output data for this IO-Link port is 1 byte.
DI
The C/Q connection works as a digital input. The length of
the process input data for this IO-Link port is 1 byte.
IO-Link
The IO-Link port uses the C/Q connection for IO-Link com-
munication. The length of the process data is determined by
the “Process data IN length” and “Process data OUT length”
parameters.
“Port cycle” parameter
The “Port cycle” parameter defines how the cycle time of the
IO-Link port is determined.
Free running (default)
The cycle time of the IO-Link port is automatically set to
match the IO-Link device connected.
Fixed cycle
The cycle time of the IO-Link port is set to the value which is
defined by the “Port cycle time (n*0.1 ms)” parameter.
The real cycle time of the IO-Link port depends on
the IO-Link device connected. If you set a cycle
time which is shorter than the minimum cycle
time of the IO-Link device, the smallest possible
cycle time is automatically set.
The web view is not updated.
Message sync
All IO-Link ports with this parameter setting start simultane-
ously with message transmission. The IO-Link device with
the longest cycle time at these IO-Link ports determines the
cycle time.
