3... INTERFACE MODULES
USING THE OMP-MODL3-48
CAUTION: The switch bank may have different numbering than the circuit
board... insure that the marking on the circuit board is followed... not the
marking on the switch banks.
Hardware Input Configuration Switches:
No hardware input configuration switches are provided on the MLIM-8. All
configuration is done via the HyperNet software (with the exception of the
Module Address setting discussed above).
Software Configuration of the MLIM-8:
The MLIM-8 module is completely configured on a channel by channel basis
from within the HyperNet software. This software configuration and
utilization of the various MLIM-8 channels in a Program Net is covered in
Chapter 7, within the Master Icon Listing in Appendix A, and within this
document.
MLIM-8; EVENT INPUT APPLICATION
The Event function of the MLIM-8 allows for the recording of the state of an ON/OFF
type input. Configured as an Event input, a channel will accept a powered input
signal (ranging from 0 to a maximum of 26VDC) or a contact closure (dry contact)
input.
For powered input signals, the MLIM-8 Event function defines
signals less than 1VDC as a Low level and greater than 4VDC
(26VDC max) as a High level.
For contact closure type inputs, power is automatically supplied
from the MLIM-8 channel circuitry via a 100Kohm pull-up
resistor (R1 in Figure 3... -32).
Channel input impedance is greater than 30K ohm.
A 40mS debounce circuit can be enabled via software which can be used to filter out
`contact bounce’ (Refer to the Master Icon Listing in Appendix A for details).
