(actual value). 0,01 %
NOTE
In order for the PLC to be able to write data from the “Rotodynamic Pump,
Output” area to the frequency inverter, it must be ensured that “Remote Request
Access” is set. This bit can remain permanently set. The data can only be written
when “Bit 0 - Access Mode” is confirmed at the PLC. This bit is flank-controlled and
must therefore be set again after, for example, a power failure. This likewise
applies to the bytes “Byte 1 - Control Mode” and “Byte 2 - Operation Mode”.
1.7.3 Definition of the feedback module available in the cyclic data exchange
The feedback module is required for transmitting an actual value for the closed-loop
control of PumpDrive 2 via field bus. In this case process control is effected by
PumpDrive 2.
