“Operating mode” parameter
The “Operation mode” parameter denes the function of the
respective IO-Link port (C/Q, L+ and L- connections). The
parameter does not inuence 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 denes 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
dened 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.
