Runtimes
Table 9-14 shows the runtimes which occur when the FB IM308C is called.
These runtimes apply when the FB IM308C can access the IM 308-C master
interface when called. If the FB IM308C does not have access, the runtime is
extended by a maximum of 1 millisecond. This can occur if a function is
repeated at a short interval for a DP slave. If the same function is pending for
another DP slave, the runtime is not increased.
