Example of Device Inhibit Control
The 1747-BSN Scanner inhibits (sets to 1) the bits in M0:e.8 through
M0:e.11 (by default) wherever there are no configured devices
present. The illustration below compares the configured devices
(G file word 2) to the groups that the scanner automatically inhibits.
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 to 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 does 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 below.
Default: The SLC processor resets all bits in this field to 0 when it
enters Run or Test mode.
