Implementation of I&M4

Post

Is the implementation of the I&M4 data record optional? The signatures/CRC in I&M4 are usable only for the safety parameterization or also for the complete device parameter set (also non safety parametersets)?

Supporting of IuM4 is optional by a device. If a device supports PROFIsafe profile it has to support IuM4 as defined by the profile.
The utilization is of IuM4 is not restricted to PROFIsafe.
