module layer determined above. The switch bank should have only ONE switch ON and the other four switches OFF.

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-2. All configuration is done via the HyperNet software (with the exception of the Module Address setting discussed above).

Software Configuration of the MLIM-2:

The MLIM-2 module is completely configured on a channel by channel basis from within the HyperNet software. This software configuration and utilization of the various MLIM-2 channels in a Program Net is covered in Chapter 7 and within the Master Icon Listing in Appendix A.

MLIM-2; EVENT INPUT APPLICATION

The Event function of the MLIM-2 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 15VDC) or a contact closure (dry contact) input.

♦For powered input signals, the MLIM-2 Event function defines signals less than 1VDC as a Low level and greater than 4VDC (15VDC max) as a High level.

♦For contact closure type inputs, power is automatically supplied from the MLIM-2 channel circuitry via a 100Kohm pull-up resistor (R1 in

♦Figure 3... -22).

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).

MLIM-2; COUNTER INPUT APPLICATION

The Counter function of the MLIM-2 provides an accumulating total of signal transitions received at its input.

Configured as a Counter type input, a channel will accept a powered input signal ranging from 0 to a maximum of 15VDC or a contact closure (dry contact) input.

♦For powered input signals, the MLIM-2 Counter function defines signals less than 1VDC as a Low level and greater than 4VDC (15VDC max) as a High level.

♦For contact closure type inputs, power is automatically supplied from the MLIM-2 channel circuitry.

In Counter mode, 16,777,216 transitions can be received before the counter will roll- over to 0 and begin counting up again. This may be a consideration during the
