PMAC2A PC104 Hardware Reference Manual

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:

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:$C080. Jumpers E5 and E6 should be configured on position 2-3 only when two Acc-1Ps are used. In this case, the I/O lines can be accessed at address Y:$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.
