Can I increase the pmon\'s heartbeat monitoring interval?

[RudiKreiner]

Because of some admittidly poor software architecture, we have an api Manager that periodically blocks for about 45 seconds, as can be seen here:

WCCILpmon (1), 2017.08.11 04:10:30.472, SYS, WARNING, 36/pmon, Blocking Manager WCCOAMDrdh(2) detected. No heartbeat since 30 seconds.
WCCILpmon (1), 2017.08.11 04:10:44.703, SYS, WARNING, 39/pmon, Manager WCCOAMDrdh(2) is no longer blocking.
WCCILpmon (1), 2017.08.11 04:20:30.659, SYS, WARNING, 36/pmon, Blocking Manager WCCOAMDrdh(2) detected. No heartbeat since 30 seconds.
WCCILpmon (1), 2017.08.11 04:20:43.381, SYS, WARNING, 39/pmon, Manager WCCOAMDrdh(2) is no longer blocking.

The blocking always ends again after about 13 + 30 seconds.

Since this behaviour is predictable and not a problem for us, we would like to increase the time for the above error message from 30 to 50 seconds,
to avoid filling our log viewer with unnecessary messages.
In the WinCC Help I could only find the config entry heartbeatTime (default 1 second) but I could not find anything that would have any effect on the above message.

I would appreciate any tips on this.

change the config entry aliveSeconds in the pmon section
