Hello, 4mA = 0 (dec) = W#16#0000 (hex) 20mA = 27648 (dec) = W#16#6C00 (hex) |
Best regards, |

Hi Cpt_KirK, I am not sure I can understand your question. Let me try to explain, 1] you can use FC106 in your step7 for analog output of 4-20mA. 2] in FC106 the "IN" value is the value that you input to give the result of 4-20mA output. 3] in FC106 the "HI_LIM" is the upper range valueand "LO_LIM" is the lower range values 4] in FC106 the "Bipolor" to be simple is the positive or negative range setting [see attach for better explaination]
5] if you set "HI_LIM" to 40.0 and"LO_LIM" to 0.0, once the "IN" value is 40.0, the "OUT" for example PQW320 will give you 27648 when you monitor from VAT table. At this time if you measure your AO card output with your meter, you will get 20.00mA. I hope this is what you are looking for. with regards, how come AttachmentUnscaling Values_ FC106_.pdf (236 Downloads) |
