Time-based IO

Time-based IO ensures that signals are output with a precisely defined response time. A
combination of inputs and outputs allows, for example, passing products to be measured
precisely or liquids to be dosed optimally.
As of firmware version V2.0.0, the IO-Link master supports the Time-based IO function. You
configure the connected IO-Link devices with time stamp functionality as normal with the
SIMATIC S7 Port Configuration Tool (S7-PCT). In the "Ports" tab in S7-PCT, set the
necessary parameters in the "Operating mode" section:
● IO-Link_Time_based_IO_IN
● IO-Link_Time_based_IO_OUT
● IO-Link_Time_based_IO_INOUT
The Time-based IO function can be used for IO-Link master with 32 bytes I/O data. Larger
I/O data ranges are not supported by Time-based IO.
Note
Time stamp function
The time stamp function requires defined address assignment (mapping).
If the address area you require is already occupied, you must modify the user data
arrangement of the IO-Link devices in the address space of the IO-Link master.
The "High-precision input/output with Time-based IO" function manual describes how to
move user data in the address space.
