SECTION 2.4
Interfacing and Using the MForce MicroDrive I/O
The MForce MicroDrive Digital I/O
The MForce MicroDrive product line is available with two digital I/O configurations, Standard and Enhanced.
The digital I/O may be defined as either active HIGH or active LOW. When the I/O is configured as active HIGH,
the level is +5 to +24 VDC and the state will be read/set as a “1”. If the level is 0 VDC, then the state will be read/set
as “0”. Inversely, if configured as active LOW, then the state of the I/O will be read/set as a “1” when the level is LOW,
and “0” when the level is HIGH. The active HIGH/LOW state is configured by the third parameter of the I/O Setup
(S1-4, S9-12) variable. The goal of this I/O configuration scheme is to maximize compatibility between the MForce
MicroDrive and standard sensors and switches.

Standard I/O Set
The MForce MicroDrive comes standard with a set of four I/O — (4) sinking or sourcing 0 to +24 VDC inputs or (4)
sinking 0 to +24 VDC outputs, which may be programmed individually as either general purpose or dedicated inputs or
outputs, or collectively as a group.
Enhanced I/O Set - MForce MicroDrive Plus2 Version
The MForce MicroDrive Plus2 Version is equipped with a set of eight I/O — (8) sinking or sourcing 0 to +24 VDC
inputs or (8) sinking or so12 to +24 VDC outputs, which may be programmed individually as either general
purpose or dedicated inputs or outputs, or collectively as a group. The eight I/O consist of two separate banks of four
points: Bank 1: IO1 - IO4, Bank 2: IO9 - IO12.
Uses of the Digital I/O
The I/O may be utilized to receive input from external
devices such as sensors, switches or PLC outputs. When
configured as outputs, devices such as relays, solenoids,
LEDs and PLC inputs may be controlled from the MForce
MicroDrive.
Each I/O point may be individually programmed to any one
of 9 dedicated input functions, 4 dedicated output func-
tions, or as general purpose inputs or outputs. The I/O may
be addressed individually, or as a group. The active state of
the line or group may also be set. All of these possible func-
tions are accomplished with the I/O Setup Variable (S1-4,
S9-12)
When the level is HIGH. The active HIGH/LOW state is

add the functionality of I/

the user to use all the
outputs, both Standard
and Enhanced, as
Sinking or Sourcing.

has the remote encoder
option, the additional
points become dedicated
to encoder functions!
