M0 File - RIO Device Reset Control
M0 Words 16 through 19 – you use these words to command a
reset (0) of RIO device outputs when the SLC processor is in Run or
Test mode. This allows you to selectively reset logical device
outputs based on a previous condition(s) that you defined. Bits 0 – 3
correspond to the logical I/O group locations within logical racks 0,
1, 2, and 3.
To command an RIO device to a reset (0) condition (from Run or
Test mode), set the bit corresponding to the starting logical address
of the device to 1. Setting bits that do not correspond to a device
starting address will not force a reset. To remove the reset condition,
reset the bit (corresponding to the device logical starting address) to
0. Refer to the mode table on page 4–20.
