SIMOCODE pro V: Prevention of Pump Blockages by Changing the Direction of Rotation
https://support.industry.siemens.com/cs/document/109478058/simocode-pro-v%3A-prevention-of-pump-blockages-by-changing-the-direction-of-rotation
In many cases, blockages in the conveying flow of wastewater pumps can be cleared by short-term reversal of the conveying direction – if necessary numeroase times. SIMOCODE pro V motor control devices detect imminent blockages and clear them by automatically changing the direction of rotation multiple times.
Blockages of pumps, sieves or screens caused by solids are a major problem in conveying wastewater. In the worst-case scenario, this can result in flooded tanks, unwanted water leakage or motor failures. What is at least required is unscheduled work to manually clear the blockages.
Using a connected current/voltage measuring module, the SIMOCODE pro V motor management and control devices can detect irregularities in the conveying flow in the form of overload or underload of the drive by evaluating the motor current imax and the power factor cos φ.
The basic parameterization of the SIMOCODE device corresponds to a reversing starter. By means of appropriate interconnections of the SIMOCODE pro V’s logic blocks, automatic reversals are performed when there is a fault in the conveying flow. These brief travels in the opposite direction are suitable for clearing imminent blockages so that an irreversible or complete blockage of the conveying flow does not occur.

Block library to read data records from SIMOCODE pro V PN for TIA Portal
https://support.industry.siemens.com/cs/document/109745043/block-library-to-read-data-records-from-simocode-pro-v-pn-for-tia-portal
By means of the block library "LSDR" (Library SIMOCODE Data Records) block library, you can read data records without much programming work and store the data in structured PLC data types for easy Access.
You can read the following data records with the block library:
Device diagnostics
Measurements
Service / statistical data
On request using the "RDREC” instruction, the "LSDR_ReadRec" function block reads one of the data records "Device diagnostics", "Measurements" or "Statistics". To allow easy access to the data, the function block stores the received serial data stream with slice access and shift operations in a structured way. For this purpose, the block library "LSDR" provides various PLC data types.
