Note from the detail above the table CIO words (n+1) to (n+7) means card address '0' is 2001 to 2007, card address '1' is 2011 to 2017, card address '2' is 2021 to 2027 etc. That is only an assumption and may be incorrect as I do not know the FB - you will have to experiment with that. That would mean that the value 1000 would be scaled to 4500 and the value 2500 would be scaled to 21300. The output of those numbers then would be scaled to real (floating point) by flt_Scaled_Min and flt_Scaled_Max to whatever you input there - say 4500/21300.
CX PROGRAMMER MEMORY CIO A T C FULL
If you only want to scale 1000 to 2500 and not the full range you would probably set the min/max at those values. Guessing that the input int_Raw_Min and int_Raw_Max are what you want to scale.
I am feeling my way here as I have never used the FB and do not know what it really does. The output will be real (floating point) (Scl_Real).
If yo wish to use the whole range of the input for scaling use 0 for minimum and 32768 for maximum - are you sure the range is not 0-4000? Non-isolated devices can cause problems - have been there before. All inputs can be 4-20ma but I would suggest you use isolated sources and not non-isolated loop powered devices. I would use the straight address 2001 as the input. For card address '0' you would use 2001 etc.
Those addresses are for special I/O card address '1'. So i need to be explained wy 0-10V = 0- FA0Ĥ) PID o/p will be also 0 to FFF - What does this mean ? By setting bits 08-11 = 4, will give me 12 bits input range, and bits 00-03 = 4 will give me 12 bits output range.Ģ) In simatic i never used Hex numbers.
CX PROGRAMMER MEMORY CIO A T C MANUAL
I found in the manual that the C+6 parameter controlls the input and output range. Please click following link to get manualġ) I doent understand what you mean by input reage( 12bit) o/p range. Like input reage( 12bit) o/p range to (12 Bit)Ģ) so analog 0-10V = 0-FA0 will in fall in 12 bit rangeĦ) If you want set analog o/p, again scale 0 to 100% to 0 to FA0Īpart from this you should go through CJ1M Programming Manual I have some questions about what MILIND DHAKE wrote earlier also :)ġ) PID consumes 36 DM, so set first parameter of PID I have found the PIDAT block but I cant find any information about the parameters. I would then used a PID self tuner for then to unscale it back to 0-10v. In simatic I would scale the 0-10V input signal into 0-100 %. I am trying to make a program where I regulate the airflow. My biggest problem is handling analog signals. How do I do this in CX-Programming ? I’ve found that workbits is from 16.00 – 89.15. If the value is INT or REAl I use MW1 ( M0.0 – M1.7) or MD1 (M0.0 – M3.7). When programming in simatic I often use memory’s, for example M0.0. The digital output address in simatic is for example Q 128.0. In simatic digital inputs address is for example I 128.0. I have read many guides but I still have trouble understanding the addresses. All my PLC knowledge is based on Simatic Step7 and FBD programming. These include 3 multi-investigator groups that operate principally in the TB/HIV space, 2 extramural research units of the South African Medical Research Council and a number of other research entities, 6 Research Chairs awarded under the National Research Foundation's South African Research Chairs Initiative (SARChI), and further areas of research foci led by individual Members.Īs a collective, the research groups include over 300 research officers and laboratory, clinical, field site and administrative support staff, 230 Masters and PhD students registered in any year, and 80 or more Postdoctoral Fellows.I am having trouble understanding how CX-PROGRAMMER works. Overall, there are more than 30 research groups. The Members may also collaborate with Affiliate or Adjunct Members. Research in the IDM is led by the Full and Associate Members, either working independently with their own research groups or in larger groups led by more than one Member. The Institute comprises 33 Full and 14 Associate Members, with 16 Affiliate Members from departments within the University of Cape Town, and 17 Adjunct Members based nationally or internationally.
