Gosai Posts: 61 Rating: (0)	Respected Sir /madam, My client had a SIMADYN with analog drive 6RA 21......it was converted to s7-400 ( FM counter modules) with old analog drives but drives facing problems with encoder feedback from the new PLC. In SIMADYN several CFC blocks were wrote to read ENCODER and convert to suitable form to transfer to drive. BLOCKS are NAV , MUL , DAC ,LIM ,NSW ....................I WANT A DETAIL DESCRIPTION OF THIS CFC blocks so i can use similar blocks in S7.

Hello, I think you will not find for all blocks similar blocks for S7, you will have to write them yourself. NAV - reads in digital encoder, calculates speed and position MUL - multiplier DAC -Digital Analogue Converter: Blockto send value toanalogue output LIM - Limiter (sometimes used as comperator) NSW - Numeric Switch: Block to switch between two values for details look here: http://support.automation.siemens.com/WW/view/en/14952400 http://support.automation.siemens.com/WW/view/en/8777232
