Q Analog Module

[Steve Cheung 0]

Dear all, Anybody have experience in Q analog module? I saw the spec at the manual for Analog Input Q64AD manual (page 3-2). I/O OCCUPIED POINT: 16 POINT. Is it wrong spelling? I found at AnS series analog manual, A1S64AD, it was 32 point. Thanks & best regards

Nope, it's correct. The Q64AD registers as a 16 bit intelligent module. Many of the Q cards are more memory efficient than their predecessors.

Hi Crossbow, Is it mean 16 bit also in the i/o addressing? How to assign the addressing below? Slot #1 QX40 ........ X0-XF Slot #2 QY10 ........Y10-Y1F Slot #3 Q64AD ........X20-X2F? Slot #4 Q68DAI .......X30-X3F? Slot #5 QY10 ........Y40-Y4F? Thanks & best regards

that's true, you can use 32-bit for each card if you want to, this is sometimes done to reserve enough I/O for bigger card in the future. nowdays this is not the big problem because addresses don't need to be in sequence (this is not true for older PLCs). Slot #1 QX40 .......... X0-XF Slot #2 QY10 ..........Y10-Y1F Slot #3 Q64AD ........X20-X2F and Y20-Y2F ;inputs and outputs cover same range Slot #4 Q68DAI .......X30-X3F and Y30-Y3F ; Slot #5 QY10 ..........Y40-Y4F so if you have Q or QnA CPU, you can do things like: Slot #1 QX40 ......... X4C0-X4CF Slot #2 QY10 .........Y510-Y51F Slot #3 Q64AD .......X120-X12F and Y120-Y12F ;inputs and outputs cover same range Slot #4 Q68DAI ......X000-X00F and Y000-Y00F ; Slot #5 QY10 .........Y040-Y04F

Hi Panic, How about if I assign 32 bit? Is it work? Slot #1 QX40 .......... X0-XF Slot #2 QY10 ..........Y10-Y1F Slot #3 Q64AD ........X20-X3F Slot #4 Q68DAI .......X40-X5F Slot #5 QY10 ..........Y60-Y6F Thanks & best regards

you can, the idea is to prevent overlapping but you can have gaps. try not to waste too much (you never know when you are going to need it).

Hi Panic, I am rather confuse, cause we need to make the marker of the whole i/o address. If it have gap, then it would never reach the exactly i/o address, isn't it? Also, if the ladder addressing diff with hardware marker should be problem. Question for your previous example. Slot #3 addressing X120-X12F, should it X520-X52F? ------------------------------------------------------------------- so if you have Q or QnA CPU, you can do things like: Slot #1 QX40 ......... X4C0-X4CF Slot #2 QY10 .........Y510-Y51F Slot #3 Q64AD .......X120-X12F and Y120-Y12F ;inputs and outputs cover same range ...? Slot #4 Q68DAI ......X000-X00F and Y000-Y00F ;.......? Slot #5 QY10 .........Y040-Y04F ....? -------------------------------------------------------------------

Hi Steve, You can check the manual for GX Developer for more details, but I suggest to try things out, not just reed. Here is a screenshot of sample program (not your case, this is just an example). I forced one of the cards to start at different address (in this example that is 400). Since this card is 16-point output card, it will occupy range Y400-Y40F.
