TRNDV – Real-time trend recording (for vector signals)

Block SymbolLicensing group: STANDARD

Function Description
The TRNDV block is very similar to the TRND block. However, it allows storing more than 4 signals. The signals are passed to the uVec input in the form of a vector. The number of processed signals is then determined by the n parameter. In contrast to the TRND block, it is necessary to set the HLD input to onto stop the execution of the block.

This block does not propagate the signal quality. More information can be found in the 1.4 section.
