10
Command
bit
"switching
status"
Byte 2
"1" = The required switching statuses of the
output channels (Byte 1) are accepted.
"0" = The required switching statuses of the
output channels (Byte 1) are ignored.
11
Command
bit
"protocol
length"
"1" = The extended 89-bit protocol is being
used; the circuit breaker is transferring
additional user data.*
"0" = The short 17-bit protocol is being used.
12
Command
bit "current
value"
"1" = The momentary input voltage and the
nominal currents set at the current selection
switch are being transferred.*
"0" = The momentary input voltage and the
momentary output currents are being
transferred.**

* This function is supports starting with Firmware 2.10 for the 787-1662 and
787-1662/0106-0000 and with Firmware 2.00 for the 787-1662/0006-1000.
** This function is supported starting with Firmware 2.10 for the 787-1662/0006-1000.
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.
