Digital Inputs
ACE-SXC module comes with 3 digital inputs. If the limit/alarm function is disabled, up
to 8 inputs can be used as general purpose inputs
Read digital input status using the
DI command. See description below:
Digital input values can also be referenced one bit at a time by the
DI[1-8]
commands.
Note that the indexes are 1-based for the bit references (i.e. DI1 refers to bit 0, not bit 1)

Table 6.2
Digital output values can also be referenced one bit at a time by the
DO[1-2] commands.
Note that the indexes are 1-based for the bit references (i.e. DO1 refers to bit 0, not bit 1)
The initial state of both digital outputs can be defined by setting the
DOBOOT register to
the desired initial digital output value. The value is stored to flash memory once the
STORE
command is issued.
Digital outputs are active low.
