8.2. 2 Submodule circuit protectors
Each circuit protector has up to two channels. The input and output data are always transmitted for both possible channels.
Depending on the number of the configured circuit protectors, in this submodule, 10 bytes input data will be exchanged with the
status of the channel, the load current and the load voltage as well as 2 bytes output data for controlling the circuit protector. It
the circuit protector used has only one channel, the status of the second channel is marked as not available (0xFF) and the load
current and the load voltage are set to 0.
Input data circuit protectors:
Design of the input bytes per circuit protector is as follows:
byte type range description
Status channel 0 byte 0 ... 255 0xFF (255) =^ no device available or wrong configuration
bit 0 = load output ON
bit 1 = short circuit
bit 2 = overload
bit 3 = low voltage
bit 4 = reserve
bit 5 = reserve
bit 6 = limit value current
bit 7 = event / or button pressed
»True« means the status is active.
Load current
channel 1 1 HighByte
2 LowByte UInt16 0 ... 65535 A standardised 16-bit-value with a resolution of 10 mA is made
available.
Example for calculation of the measuring value:
value (150)/100 =^1.50 Amps
Load voltage
way 1 3 HighByte
4 LowByte UInt16 0 ... 65535 A standardised 16-bit-value with a resolution of 10 mV is made
available.
Example for calculation of the measuring value:
value (2512)/100 =^25.12 Volt
Status channel 2 5 byte 0 ... 255 0xFF (255) =^ no device available, wrong configuraiton or 1-chan-
nel device used
bit 0 = load output ON
bit 1 = short circuit
bit 2 = overload
bit 3 = low voltage
bit 4 = reserve
bit 5 = reserve
bit 6 = limit value current
bit 7 = event / or button pressed
»True« means the status is active.
Load current
channel 2 6 HighByte
7 LowByte UInt16 0 ... 65535 A standardised 16-bit-value with a resolution of 10 mA is made
available.
Example for calculation of the measuring value:
value (150)/100 =^1.50 Amps
Load voltage
way 2 8 HighByte
9 LowByte UInt16 0 ... 65535 A standardised 16-bit-value with a resolution of 10 mV is made
available.
Example for calculation of the measuring value:
value (2512)/100 =^25.12 Volt
