ACC65E and other IO accessory cards

As described in the PPmac documentation you can address the ACC65E and other IO cards using their physical address. See the manual "Power PMAC Suggested IO Pointer Declarations.doc" under thread http://forums.deltatau.com/showthread.php?tid=85 In the PPmac script language, if you prefer to work with structures then you can use them directly in your code and in the terminal of the IDE or you can use #defines to add more meaning to the names. Here is a sample for PPMAC script language with an ACC65E. The first uses the specific ACC65E[] structure. The second uses the general GateIo[] structure. The third uses the IDE's auto assignment feature for Pointer (M-variables). All are essentially equivalent. //---------------------- specific ACC65E[] defintions ---------------- // make bit pointers to the ACC65Es // ACC65E[0].DataReg #define c0MyInputs1_8

Hi Brad, Is there a way to use a local variable to specify the bit to be accessed within a motion program or plc? I tried these statements, neither of which work: gateio[0].datareg[L1].L2.1 gateio[0].datareg[L1].(L2).1 It works to use L1 to specify the data register, but it does not work to use L2 to specify the bit number. Is there a simple way to do this, or do I have to use L2 to create a mask and then read or read-modify-write the entire register? Also, I noticed that accessing the individual bits seems to work fine without the trailing ".1": if you enter gateio[0].datareg[0].0 at the gpascii command line, it returns the value of the input. gateio[0].datareg[0].0.1 works as well. Thanks, Erik

Are you trying to define an M-Variable to this location? If so, no, you cannot dynamically change the assignment of the bit number. The best idea would be to just point to the whole word and dynamically mask to get the bit you desire. Regarding gateio[0].datareg[0].0 vs. gateio[0].datareg[0].0.1, yes, they are equivalent. When you omit the .1 at the end, PMAC assumes you wanted to just look at 1 bit.

I just want to be able to access a particular bit but I won't know which particular bit until run-time. I thought about dynamically masking as you mention. That works fine for reads, but if you only want to write to a single bit, then you have to do a read-modify-write on an entire register to make it work (that's probably how it is done underneath in the PPMAC anyway). So I need to read the register to find the values of the other bits that I don't want to change, change my particular bit, and then write the entire word back to the register, which should only change my particular bit. Thanks, Erik

I understand what you mean. What you could do is actually declare M-Variable pointers to all of the bits you want beforehand, one M-Variable per bit, and then you can access them using array notation by bit number. For example if you predefine [code] #define c0OutBaseIndex 7000 #define BitNumber P7000 #define c0Out01 M7000 #define c0Out02 M7001 #define c0Out03 M7002 #define c0Out04 M7003 #define c0Out05 M7004 #define c0Out06 M7005 #define c0Out07 M7006 #define c0Out08 M7008 c0Out01->GateIo[0].DataReg[3].0.1 ;// output 01 c0Out02->GateIo[0].DataReg[3].1.1 ;// output 02 c0Out03->GateIo[0].DataReg[3].2.1 ;// output 03 c0Out04->GateIo[0].DataReg[3].3.1 ;// output 04 c0Out05->GateIo[0].DataReg[3].4.1 ;// output 05 c0Out06->GateIo[0].DataReg[3].5.1 ;// output 06 c0Out07->GateIo[0].DataReg[3].6.1 ;// output 07 c0Out08->GateIo[0].DataReg[3].7.1 ;// output 08 [/code] Then you can just cycle through them by M-Variable array indexing notation as such: [code] BitNumber = 0; M(c0OutBaseIndex + BitNumber) = 0; // Sets GateIo[0].DataReg[3].0.1 = 0 BitNumber = 5 M(c0OutBaseIndex + BitNumber) = 1; // Sets GateIo[0].DataReg[3].5.1= 1 [/code] That's one way to do it.
