The CBP optional board (PROFIBUS communications board) is for linking drives to higher-level automation systems via PROFIBUS.

The optional board has three LEDs (green, yellow, red) for providing information on the current operating status.

Voltage is supplied from the basic unit.

The bus system enables very fast transfer of data between higher-level systems (e.g. SIMATIC, SIMADYN D, PC/PGs) and the drives. Access to the drives is made in the bus system according to the master-slaves method. The drives are always the slaves and each slave is clearly defined by its address.

In the PKW area, all data intended for reading or writing parameter values and for reading parameter characteristics are transferred.

In the PZD area, all information necessary for guiding a variable-speed drive is transferred. Control information (control words) and setpoints are given to the slaves by the PROFIBUS DP master. Information on the status of the slaves

(status words) and actual values are transferred in the reverse direction.

The length of the PKW and PZD data portions in the telegram is determined by the master. The master also specifies the baud rate. Only the bus address and,if necessary, the telegram failure time are set on the slave.

If the inverters/converters are ordered with optional functions, the optional boards are already installed in the units when they are delivered.

It is possible to retrofit optional boards and this can be carried out by the user.

For this purpose, there are either three or up to six slots on the basic unit depending on the type of construction for mounting the optional boards.

An exact description of installation is included with the relevant basic unit. As the unit has to be removed and opened in order to install optional boards, attention must be paid to the ESD measures. Please refer to the operating instructions of the basic unit in this regard.
