IEC 101 Slave: Master Connected and startup request
Hi,
I have a zenon logic project containing IEC60870S2 Slave profile.
I created a variable (TID=0, IOA=1) permits to understand if a Master is connected to the slave.
Problems are:
1)
when Master-Slave connection is up, value of the variable changes to 1.
when Master-Slave connection fails, value doesn't change to 0, it remains 1 also if Master is not connected: only closing and rebooting straton project, value of the variable change to 0.
I thought variable value returns to 0 when the connection ends.
2)
This is not a problem but a question.
In zenon logic, is it possible to delay IEC101 slave driver starting??
I use zenon logic like a gateway, I have a 61850 driver reads data from the field and gives it to 60870 slave. At the startup, 60870 Master receives invalid values because zenon logic didn't yet read 61850 values.
Thanks
