jake4eng posted a topic in Allen BradleyHello All! I am having difficulties mapping register values. In the TURCK register there are 24 unique register bytes corresponding to different value registers (8bit x 24). These 24(8bit) bytes were mapped into RSLOGIX 5000 as 12(16bit) INT words ....INT .. This means there are 2 bytes (2 unique register values) inside each INT word. WHAT I NEED TO ACHIEVE: 1. (BLUE outline in drawing) Write/Map a value of "32" into byte 7 of the TURCK register so effectively starting at INT.8 in RSLOGIX Drawing1-Model.pdf This will enable the value of CNT1 (encoder count) to be registered in bytes 8-11... 2. (PINK outline in drawing) READ/MAP the values registered in bytes8,9,10 and 11(4x8bits) into a SINGLE 32bit INT value which will tell me the CNT1 value of my encoder. I am having problems when ever I try to COP a value of 32 (no matter what kind of array it's sourced from) into INT.8 & I haven't tried to map/read the values of bytes 8-11 CAN SOMEONE PLEASE HELP EXPLAIN HOW TO ACHIEVE THIS?! Thanks for your input EVERYONE! :D Drawing1-Model.pdf
jake4eng posted a topic in Allen BradleyI am having problems expressing an ANALOG OUTPUT 16bit INT word (0-10V Proportional Valve Voltage) as a REAL decimal number. From my understanding the word is divided into 2 (8bit) bytes...one representing the whole number value and the second the decimal value. We're using BL20 I/O Module (german therefore LSB first I believe). I need to MOV/COP (read) the value, CONVERT it into a REAL number, Manipulate the REAL VALUE, then CONVERT the MANIPULATED REAL Value back into a 16bit INTEGER & WRITE the NEW Integer Value into Proportional Valve Voltage Location. I also have a similar situation regarding our Incremental Encoder. In this scenario the pulse count is obviously a whole number (no decimals) where 4 (16bit) bytes represent the REAL Count Value.. I have read other posts on similar conversion topics and understand the general premise, but I'm having problems specifying write parameters.. - i.e. writing bits 0-7 from an INT into SINT (HIGH BYTE representing the whole # value? ) and writing bits 8-15 into SINT (LOW BYTE representing the decimal value) THEN CONVERTING into REAL # (Voltage fed to Proportional Valve) ...manual section... page 282&283 http://pdb2.turck.de/repo/media/_us/Anlagen/d300717.pdf - i.e. writing bits 0-15 from INT , INT , INT and INT into a LINT (not sure if correct) THEN CONVERTING into REAL # (Encoder Count) ...manual section... page 17 (current count value) http://pdb2.turck.de/repo/media/_en/Anlagen/D301224.pdf ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED... project file if interested.. https://sites.google.com/site/lyncedrgb/eva/untitledpost-2/StellaPLC.ACD
