Using DeviceLogix Appendix G
Bit Inputs
Available bit inputs to the DeviceLogix program include:
The function of the expansion port inputs depends on the card installed in the
given port. Ta b le 72
shows how the bit inputs are mapped for each card type:
Bit Outputs
Bit Outputs are used to connect to real-world output devices (pilot lights,
relays, etc.) that are wired to an auxiliary relay in the controller. Available bit
outputs are shown in Table 73
.
