Prioritized startup
Prioritized startup
Prioritized startup is a PROFINET IO function in a PROFINET IO system with IRT and RT
communication. It reduces the time needed for correspondingly configured IO devices to
return to cyclic user data exchange.
The function accelerates the startup of IO devices in the following cases:
●
After recovery of supply voltage
●
After station recovery
●
After activation of IO devices
Note
Dependency of the startup time
The interface module permits startup times from 0.5 s.
The startup time depends on the number and type of modules.

Submodules
Submodules
The IM 155-6 PN/2 HF interface module supports the division of I/O modules into up to 4
submodules. This allows parts of an I/O module to be separately configured and
parameterized.
A maximum of 256 submodules is supported, whereby 4 submodules are used for the
interface module and one submodule for the server module.
You can assign each of these submodules to different IO controllers.
The following functions are only executed if you have configured submodule 1 during
configuration:
●
Firmware update
●
Write I&M data
●
Calibration
●
