Product Information _________________________________
Revision:
Firmware version:
Compatibility:
CPU001-BB
1.10
VersaPro software version 1.0
New Features ____________________________________
This version of CPU001 provides:
S Support for intelligent I/O modules.
S Scaling function blocks.
Two new function blocks can be used to scale input data.
One function block is for unipolar (unsigned) input data. The other
function block is for bipolar (signed) input data.
S Drum Sequencer function block.
This new function block works like a mechanical drum sequencer.
It allows a sequence of output combinations to be selected in turn.

Preinstallation Check _____________________________
Carefully inspect all shipping containers for damage. If any equipment
is damaged, notify the delivery service immediately. Save the damaged
shipping container for inspection by the delivery service. After
unpacking the equipment, record all serial numbers. Save the shipping
containers and packing material in case it is necessary to transport or
ship any part of the system.
Module Installation _________________________________

Modules must be mounted on a
horizontal DIN rail.
1. Allow sufficient finger clearance
for opening CPU door.
2. Allow adequate clearance for
serial port cables.
3. Allow adequate space for power
wiring.
The CPU with power supply attached
fits into a 70mm deep enclosure.
Rated thermal specifications for the
CPU module is based on a clearance
of 2” above and below the equipment
and 1” to the left of the CPU module.
Installing the CPU on the DIN Rail
The CPU and connecting carriers must be
installed on the same section of 35mm x
7.5mm DIN rail. The rail must have a
conductive (unpainted) finish for proper
grounding. For best stability, the DIN rail
should be installed on a panel using
screws spaced approximately 6 inches
(5.24cm) apart.
The CPU snaps easily onto the DIN rail.
No tools are required for mounting or
grounding to the DIN rail.
Before joining module carriers to the CPU, remove the connector cover on
the righthand side of the CPU. Do not discard this cover, you will need to
install it on the last carrier, to protect the connector pins from contamination
and damage during use.
Panel-Mounting __________________________________
If excessive vibration is a factor the CPU should also be screwed down to
the mounting panel.
Note 1. Tolerances are +/- 0.13mm (0.005in) non-cumulative.
Note 2. 1.1-1.4Nm (10-12 in/lbs) of torque should be applied to M3.5 (#6-
32) steel screw threaded into material containing internal threads
and having a minimum thickness of 2.4mm (0.093in).

Removing the CPU from the DIN Rail ___________________
1. Turn off power to the power supply.
2. (If the CPU is attached to the panel with a screw) remove the power
supply module. Remove the panel-mount screw.
3. Slide the CPU away from the other modules until the connector on the
right side disengages from the next carrier.
4. With a small flathead screwdriver, pull the DIN rail latch outward while
tilting the other end of the module down to disengage it from the DIN
rail.

The Drum Sequencer Function _____________________
Please add the following information about the Drum Sequencer
function to your copy of the PLC User’s Manual.
Description of the Drum Sequencer Function
The Drum Sequencer function is a special program instruction that
operates like a mechanical drum sequencer.
The Drum Sequencer steps through a set of potential output bit
patterns and selects one based on inputs to the function block. The
selected value is copied to a group of 16 discrete output references.
Enable
Step
Reset
Pattern
Dwell Time
www.DataSheeFta4uUlt.Tciommeout
DRUM
Control Block
Length
OK
Out
Drum Coil
Dwell Timeout
Timeout Fault
First Follower
Power flow to the Enable input causes the Drum Sequencer to copy the
content of the selected reference pattern to the Out reference.
Power flow to the Reset input or to the Step input selects the reference
to be copied.
The Control Block input is the beginning reference for the Drum
Sequencer function’s parameter block, which includes various
information necessary to use the function block.
Parameters of the DRUM SEQ Function
Input/ Choices
Output
Description
Enable Flow The Enable input controls execution of the function.
Step Flow The Step input can be used to go one step forward in the
sequence. When the Enable input receives power flow and
the Step input makes an off to on transition, the drum
sequencer moves one step. . When Reset is active, the
function ignores the step input.
Reset
Flow The Reset input can be used to select a specific step in the
sequence. When Enable and Reset both receive power flow,
the function copies the Preset Step value in the Control
Block to the Active Step reference, also in the Control Block.
Then the function block copies the value in the Preset Step
reference to the Out reference bits. When Reset is active,
the function ignores the Step input.
Pattern
R, AI, AQ
The starting address of an array of words, each representing
one step of the Drum Sequencer. The value of each word
represents the desired combination of outputs for a particular
value of ACTIVE STEP. The number or elements in the
array is equal to the Length input.
Dwell
Time
R, AI, AQ,
none
This optional input array of words has one element for each
element in the Pattern array. Each value in the array
represents the dwell time for the corresponding step of the
drum sequencer in .1 second units. When the dwell time
expires for a given step the Dwell Timeout bit will be set.
If a Dwell Time is specified the drum can not sequence into
its next step until the Dwell Time has expired.
Fault
Timeout
R, AI, AQ,
none
This optional input array of words has one element for each
element in the Pattern array. Each value in the array
represents the fault timeout for the corresponding step of the
drum sequencer in .1 second units. When the fault timeout
has expired the fault timeout bit will be set.
Input/ Choices
Output
Description
Control
Block
Length
R
CONST
The beginning reference address of the function's parameter
block. The length of the Control Block is five words. A more
complete description of what is contained within this block is
listed below.
Value between 1 and 128 denoting the number of steps.
OK Flow, none OK is energized if Enable is On and no error condition is
detected. If Enable is Off this output will always be off.
OUT I,Q,M,T,G, A word of memory containing the element of the Pattern
R,AI,AQ Array that corresponds to the current ACTIVE STEP.
Drum
Coil
I,Q,M,T,G, This optional bit reference is set whenever the function block
none is enabled and ACTIVE STEP is not equal to PRESET
STEP.
Dwell I,Q,M,T,G, This optional bit reference is set if the dwell time for the
Timeout none current step has expired.
Timeout I,Q,M,T,G, This optional bit reference will be set if the if the drum has
Fault none been in a particular step longer than the step's specified
FAULT TIMEOUT
First
Follower
I,Q,M,T,G,
none
This optional array of bits has one element for each step of
the Drum Sequencer. No more than one bit in the array will
be ON at any time and that bit will correspond to the value of
ACTIVE STEP.
Parameter Block for the DRUM SEQ Function
The parameter block (control block) for the Drum Sequencer function
contains various information needed to operate the drum sequencer.
Active Step
Address
Preset Step
Address + 1
Step Control
Address + 2
Timer Control
Address + 3, Address + 4
Active Step
The active step value specifies the element of the
PATTERN array to copy to the OUT output memory location. This is used
as the array index into the Pattern, Dwell Time, Fault Timeout, and First
Follower arrays.
Preset Step
A word input which is copied to the ACTIVE STEP
output when the RESET is ON.
Step Control
A word that is used to detect OFF to ON transitions on
both the STEP input and the ENABLE input. The Step Control word is
reserved for use by the function block, and must not be written to.
Timer Control Two words of data that hold values needed to run the
timer. These values are reserved for use by the function block, and must
not be written to.
Notes on Using the Drum Sequencer Function ________
1. The Dwell Timeout Output Bit is cleared the first time the drum is in a
new step. This is true:
S Whether the drum is introduced to a new step by changing the
Active Step or by using the Step Input.
S Regardless of the Dwell Time Array value associated with the
step (even if it is 0).
S During the first sweep the Active Step is initialized.
2. The Active and Preset Step of the Drum Sequencer's control block
must be initialized for the Drum Sequencer to work or to pass power
flow. Even if the Active Step is in the correct range(between 1 and
length of the pattern array) and the Preset Step is not used, the drum
will not function if the Preset Step is not in the proper range.
