Inputs and Outputs
For the I/O Geo MACRO drive, use the 24-bit node register of the activated node. Using the I/O is
accomplished by writing to a node register to activate the desired outputs and reading the same node register to
read the status of the inputs. In other words, the one 24-bit node register is used for both inputs and outputs.
This is efficient because it allows the 48-bits of information to be processed using one 24-bit word and
minimizes the number of nodes needed for the IO data transfers for each MACRO device. The only drawback
to this technique is that the user will have to keep track of the status of the outputs (see example).
Example: If node 2 is activated at both the Master and MACRO Device, make the following definitions
to read and write to the inputs and outputs.
M3000->X:$78420,0,24 ;Actual Input/Output Word
M980->Y:$10F0,0,24 ;Input Image Word1, free user memory space
M982->Y:$10F1,0,24 ;Output Image Word1, free user memory space
M3012->X:$78420,8,4 ;four inputs
M3013->X:$78420,12,4 ;four outputs
Open PLC1 Clear
M980=M3000 ; Input Image Word equals Actual Input Word
Process Inputs and Build image output word (M982) – User code
M3000=M982 ; Set Actual Output Word equal to Output Image Word1
