6. InTERfACES
6.1 SySTEM InTERfACES
The bus module is connected to the respective system interfaces of the
power controller via X1 to X8 (4-lead, 2x2 twisted, joint screen).
The transmission rate is 38,400 Bd.
The asynchronous signals are transmitted with 8bit, no parity, one stopbit.
The log begins with STX, followed by an identification key, the data and
ends with a check sum. faulty logs are ignored.
6.2 MODBUS InTERfACE
This interface, in accordance with RS485, is designed for a transmission
rate up to 230.4 kbd. The allocation corresponds to the industrial standard.
The length of the data line and the transmission rate are in fixed relation.
The maximum lengths of the bus master given in the manufacturer’s
specifications may not be exceeded.
