If there is an existing connection between WAGO devices, the time between
the received packets is measured. If there is a significant timeout, warnings or
error messages are sent (see Table 8). The typical time response is signifi-
cantly more high performance than the upper limits given here for warnings
and errors.

If the time limits cannot be adhered to, warnings or error messages are issued
via acyclic diagnosis functions (LED displays, see Section 2.1.1.3) or cycli-
cally through the status byte of the process image (see Section 2.1.1.8.1.1).
For optimal time response, a valid piconet configuration must exist. If the
master cannot establish a connection to all slaves, the attempt to reintegrate
these devices leads to interruptions in data communication (see also "SetRe-
connectionTimePeriod", Appendix 6.3.5.34). To prevent this, you can tempo-
rarily remove defective devices from the piconet. No change in configuration
is required for removing the devices; simply set the affected devices to "not
linked" in the "real-time" communication profile. The master then no longer
integrates these devices during this time.
With the next change in operating mode or restart, the master will again try to
connect to all devices.
Note
Only connections to WAGO devices can be configured in the real-time pro-
file.
