Default: 10
Time for which the V25 pauses in rapid-blinking mode, if all modules are not in the
system.
Standby CPU
Interval (x131ms)
Default: 2
Time delay in which the V25 of a standby CPU waits until the "Life data ack." is
sent. Required in standby-systems for differentiation of the CPUs.
Module check
Default: 0 (deactivated)
Time in which the V25 sends test telegrams to the modules, in order to check them.
