Using high-speed outputs for output cams on D410

Using high-speed outputs for output cams / DOs with D410
Output cams are defined as being the position-dependent output of switching signals. The
TO output cam and TO cam track technology objects control the output of the output cam for
SIMOTION.
The onboard digital outputs of the SIMOTION D410 can be used as an output for the output
cam or a high-speed output with write access to the user program. In order to be able to use
the high-speed outputs, one of the 39x message frames must be created.
Note
If I/O data is transferred using bus message frames, the update of the I/O data is subject to
the set bus cycle. This means an I/O using a 39x message frame can change its status just
once in each bus cycle of the PROFIBUS Integrated.
In the case of SIMOTION D410 onboard outputs, the outputs are controlled using direct write
accesses to the hardware (i.e. bypassing the message frame). This means:
• Write accesses to digital outputs act with a particularly short delay time because the write
• A more accurate output of the cam output is possible
For fast write accesses from the user program, the resulting delay time has the following
form:
• User program delay time -> terminal register: Maximum 75 μs
• Load-dependent output delay time of the hardware for D410:
High-speed outputs of output cams
If you use the output as high-speed output of a cam output, for the configuration of the TO
output cams / TO output cam track, enter the logical hardware address and the bit number of
the used output in the configuration screen form of the TO.

High-speed digital outputs
If you use the output as high-speed digital output, create an I/O variable in SIMOTION
SCOUT. The same addresses should be used for the high-speed digital outputs as those
normally used for the digital outputs.
