10.  Outputs refresh rates 
There are the following refresh rates for binary and analog outputs. 
Analog Output on a controller 
Binary Output on a controller 
100ms @ minimum puls length 20ms 
On demand if there is a „fast“ protection configured on 
this output 
Analog Output on an external 
module 
80ms times available modules for configuration (i.e. 4 
modules available in standard FW results in 320ms 
period) 
Binary Output on an external 
module 
On demand when there is a change in binary state 
with period 100ms times available modules for 
configuration if there are no changes in binary states 
(i.e. 12 modules available in standard FW results in 
1200ms if there are no changes) 
Once per voltage period (20ms@50Hz) 
Once per voltage period (20ms@50Hz)
