STOP bit (1.5 pulse cycles) 
For 17-bit protocol: Bit 18 
For 89-bit protocol: Bit 90 

*   This function is supports starting with Firmware 2.10 for the 787-1668 and 

787-1668/0106-0000 and with Firmware 2.00 for the 787-1668/0006-1000. 

**   This function is supported starting with Firmware 2.10 for the 787-1668/0006-1000. 

 
Depending on the valence of bit 12 (byte 2), either the set nominal currents or the 
momentary output currents are transferred in addition to the momentary input 
voltage (see Table 22). 

Electronic circuit breakers without active current limitation supply only the 
momentary input voltage and the set nominal currents. Output currents are not 
transferred.
