Q/I
I
The module’s inputs and outputs can be re-configured for a wide variety
of applications:
▪The high-speed counter inputs can be set up as standard high-
speed inputs, as four type A counters, as two type A counters plus
one A-quad-B counter, or as one type A-quad-B counter with
homing capability.
▪Four of the outputs can be configured as pulse-width modulated
(PWM), pulse train, ramping pulse train, or HSC outputs.
When configured for PWM operation, the frequency of each PWM
output is selectable in the range of 22Hz to 2 KHz. The duty cycle of
each PWM output can be set from 1 to 100% depending on the
frequency of the PWM output. See the Minimum % Duty Cycle vs. PWM
Output Frequency graph in the I/O Modules Manual.
When configured as pulse train or ramping pulse train outputs, the sum
of frequencies may be up to 5,000 pulses per second. Acceleration and
deceleration can be selected from 10 to 1,000,000 p/s2.
Power for module operation comes from the backplane. Output devices
must be powered by external voltage.
LED Indicators
Individual green field-side LEDs show the on/off status of each point.
The green FLD PWR LED indicates the presence of field power for the
DC outputs.
The OK LED indicates module status.
▪On green indicates normal operation.
▪Flashing green indicates boot mode or update
▪On Amber indicates self diagnostic error
▪Off indicates no 3.3V power present.

Thermal Derating
The number of points that can be on at the
same time depends on the surrounding air
temperature, voltage, and the type of carrier
on which the module is installed. To meet
thermal specifications, the module must be
installed on a horizontal DIN rail. There is
no thermal derating at 24VDC for
surrounding temperatures up to 42°C, or at
30VDC for temperatures up to 26°C. For
derating curves at higher temperatures, see

Product Description
Firmware version:
1.22
Firmware
upgrades:
The upgrade kit 44A748026-G04 can be
downloaded free of charge from www.ge-
ip.com/support.
Functional Compatibility
The MDD841 requires the minimum versions listed below.
▪PLC CPU programming software version 1.5 or later.
▪Ethernet NIU EBI001 firmware version 1.0 or later
▪Genius NIU GBI001 firmware version 2.0 or later
▪Profibus NIU PBI001 firmware version 2.0 or later
▪DeviceNet NIU DBI001 firmware version 2.10 or later
The DeviceNet NIU does not support software configuration. Therefore,
analog modules used with the DeviceNet NIU must be auto-configured
and use only their default configuration settings.
Operating Notes/Restrictions
▪If hot insertion of a module is done improperly, the operation of
other modules on the same backplane may be disrupted. See
Installing a Module on a Carrier in the VersaMax Modules Manual,
GFK-1504.
▪If a small span is configured and on/off presets are set close
together, the following minimum limits should be maintained:
For This Count
Frequency:
Minimum Span between On Preset
and Off Preset Should Be:
10KHz
10 counts
5KHz
5 counts
2KHz
2 counts
1KHz
1 count
Less than 1KHz
No gap required
▪If the minimum span per count frequency is not maintained, the
output LED may flicker.
▪Any data placed in %Q or %AQ memory must remain in memory
for at least 20 milliseconds.
▪If the module is configured for Hold Last State and the watchdog
timer in the CPU or NIU that controls it fails, the module Holds Last
State briefly, then switches to default values. This is due to the
module being reset by the CPU or NIU.
▪When using pulse-trains and ramping pulse-trains, the sum of the
frequencies of all simultaneously-executing outputs should not
exceed 5,000 pulses/second. Exceeding this speed limit could
cause the pulse-trains to stop prematurely, or cause the module’s
watchdog timer to expire.

▪The module can perform the “pulse-train with ramp” function on
four output channels. However, no more than two should be used
simultaneously. If more than two ramps are executed at the same
time, one or more of them may terminate before the specified
number of pulses have been generated.
▪When the module’s Output Stop Mode is configured for Hold Last
State, the outputs will only respond in Stop mode if the Enable
HSC/PWM/Pulse Train Output %Q bits are still set. These bits will
remain set when the %Q memory is configured for default only
when the default value for the bits (%Q21-%Q24) is set to 1 on the
“Output Parameters” tab in the modules Hardware configuration.
Alternatively, the %Q memory can also be configured to Hold Last
State on the “Module Parameters” tab in the Hardware
Configuration.

Default Operation
Inputs 1 - 8 are one group of high-speed counter inputs. These inputs
operate as:
▪Four Type A counters.
▪Each counter counts upward.
▪When a counter reaches its upper limit, it wraps around and starts
over.
Inputs 9 - 16 are one group of standard inputs with a common return.
Inputs 17 - 20 are one group of standard inputs with a common return.
Four of the outputs are High-speed Counter outputs. Each High-speed
Counter output is dedicated to a corresponding High-speed Counter
input.
Eight additional outputs are standard outputs.
The counter outputs use a default ON preset of +32,767, and an OFF
preset of 0. If the count reaches the ON preset, the counter’s output is
turned on. If the count reaches the OFF preset, the counter’s output is
turned OFF.
When the system is in Stop mode, the High-speed Counter outputs
continue to respond to the counter inputs and the standard outputs turn
off. The output presets continue to operate as if the CPU/NIU were
present, changing state to reflect the counter Accumulators.
In default mode, the module can temporarily change this basic operation
in response to up to four commands from the CPU or NIU. These
commands can be sent to the module in its regular output data.
▪Each counter output can be turned on or off on command.
▪Each counter can be reset to 0.
▪Each counter’s accumulator (current count) register can be loaded
with any value from -32768 to 32767.
▪Each counter’s lower and upper limits can be changed.
▪Each counter’s accumulator can be incremented by a specific
amount above its present actual value.
▪The count direction can be changed to down (or back to up).
▪The timebase for each counter’s counts-per-timebase, which
measures its rate of counting, can be changed from1000mS to any
value from 10mS to 65530mS.
▪Each counter’s preload value can be changed.
Configurable Features
The default parameters of this module can be used in many applications.
The module can be software-configured when it is installed in a PLC
system, or an I/O Station controlled by a Network Interface Unit that
supports software configuration.
The module is configured at startup. After configuration, the module
begins providing signals from the voltage or current output devices
connected to it to the CPU or NIU.

Data Commands
Data Commands can be used to temporarily change the counter
parameters listed below. There is no limit to the length of time a
command can be present in the output words. The module acts on a
command only when it detects a change in the command words.
However, these changes are lost when the module is powered down
and when a new configuration is stored from the programmer.
Data Commands can be sent to the module as part of its analog (AQ)
data. When the module is installed in a PLC, the PLC CPU can also
send Data Commands using the COMREQ function.
Load Accumulator
Loads any value within a counter’s limits directly into the
Accumulator.
Load High Limit
Sets the High and Low limit to any value in the counter
range.
Load Low Limit
Load Accumulator
Increment
Offsets a counter Accumulator by up to +127 or –128
counts. This can be done at any time, even while the
counter is counting at maximum rate.
Set Counter
Direction
(Type A only) Changes the count direction of a type A
counter.
Load Timebase
Changes the time interval used for the counts/timebase
word data. The range is 10 to 1000mS in 10mS intervals.
Load Home Value
Changes the home value for the Type B2 counter.
Load ON Preset
Sets up the output turn on points within the counter range.
There is one output associated with each counter.
Load OFF Preset
Sets up the output turn off points within the counter range.
Load Preload
Changes the count value loaded into the counter
Accumulator when the Preload input is activated.
Load Stop Mode
(or Resume
Decelerate Mode)
Changes a Pulse Train output’s deceleration to stop the
Ramp immediately when the Output Enable bit goes Off.
The Ramp function must be enabled. The same
command can be used to reset the output to Decelerate
mode.
Load
Acceleration
Changes a Pulse Train output’s acceleration. The Ramp
function must be enabled. Both acceleration and
deceleration can be selected from the range of 10 p/s2to
1,000,000 p/s2. The default for both is 1,000,000.
Load
Deceleration
If the Ramp function is enabled, this command changes a
Pulse Train output’s deceleration.
Load Correction
Sets the change (in microseconds) that should be applied
to the duty cycle of a Pulse Train output. The range is 0 to
200 microseconds.
