PMAC2A-PC/104 Software Setup 25

Using Flag I/O as General-Purpose I/O

Either the user flags or other not assigned axes flag on the base board can be used as general-purpose I/O

for up to 20 inputs and 4 outputs at 5-24Vdc levels. The indicated suggested M-variables definitions,

which are defined in the PMAC2 Software reference, allows accessing each particular line according to

the following table:

Channel Number

Flag Type

#1 #2 #3 #4

Note

When using these lines as regular I/O points the appropriate setting of the Ix25

variable must be used to enable or disable the safety flags feature.

General-Purpose Digital Inputs and Outputs

If one ACC-1P is present on the PMAC2A-PC/104 stack configuration then its jumpers E5 and E6 should

be set at the default position 1-2. In this case the lines on its J7 general-purpose I/O connector will be

mapped into PMAC's address space in register Y:$C080. Jumpers E5 and E6 should be configured on

position 2-3 only when two ACC-1P are used. In this case, the I/O lines can be accessed at address

Y:$C0C0.

If no ACC-1P is present on the PMAC2A-PC/104 stack configuration, and only ACC-2P is used, then

jumper E5 on the ACC-2P board should connect pins 1 and 2. In this case the lines on its JOPT general-

purpose I/O connector will be mapped into PMAC's address space in register Y:$C080.

If both ACC-1P and ACC-2P are used then jumper E5 on the ACC-2P board should connect pins 2 and 3

and its I/O lines can be accessed at address Y:$C0C0.

Typically, these I/O lines are accessed individually with M-variables. Following is a suggested set of M-

variable definitions to use these data lines.
