Overview

1.1
Features
The Series 505 High Speed Counter (HSC) module (PPX:505-7002)
provides two independent high-speed counter channels.
Each channel has the following features.
Four counter modes:
Pulse counter
Quadrature counter modes: 1X, 2X, 4X
A 10 kHz count rate with a minimum pulse width of 25 s.
Four inputs:
two count inputs
reset
inhibit
Two field outputs, each controlled by a separate programmable preset.
LED indicators display the status of the A and B count inputs, and of
Y1 and Y2 outputs.
All inputs may be sinking or sourcing (with external 24 VDC power
supply).
The HSC module operates asynchronously from the controller scan. You
can program the controller to monitor the HSC and/or to provide high-level
control of the HSC’s operation. To support these functions, the HSC
provides reset, inhibit, output and counter status to the controller and
accepts reset and inhibit commands, and preset values from the controller.
! 1-2
The HSC module controls its four outputs. If the controller switches from the Run
mode to the Program mode, the HSC continues to function as programmed, and
outputs may be activated by the HSC. This means that if you switch the controller
to Program mode, any devices controlled by the four outputs of the HSC will
continue to operate as programmed.

Inputs
The HSC module has two independent channels. Each channel has four
inputs.
Reset
Inhibit
Two counter inputs
Each input may be used as either sinking or sourcing (with external 5–24
VDC power supply). The input signals are connected to the field wiring
terminal block on the front bezel.
Counter InputsąEach channel has two counter inputs — Input A and
Input B.
ResetCurrent flow through the reset input sets the channel’s counter to
zero. The counter will be held at zero until the reset input becomes
inactive.
InhibitąCurrent flow through the inhibit input inhibits the channel from
counting. The counter holds at the last value and does not change until the
inhibit input becomes inactive.
NOTE: When in the pulse counter mode, if the A or B input is in a
different state at the beginning and end of an inhibit signal, the count will
change according to the normal counting logic. If both A and B inputs are
in different states, the change may be as much as two counts.
NOTE: There are also software reset and inhibit functions. See Section 3.

Counting Modes
1.5.1
Pulse Counter
Mode
Each channel has two inputs, A and B. In the pulse counter mode, counting
occurs on the rising or falling edge of the incoming pulses. The relationship
of the states of these two inputs determines the direction of the count. See
Table 1-1. Typical devices for counting are high-speed static switches or
incremental encoders.

In the pulse counter mode, the channel senses the edges of the A or the B
input to count up or down. See Figure 1-4. To reliably record this transition
from low to high, the pulse width must be at least 8 s.

1X Quadrature
For quadrature mode, each channel counts according to rising and/or
falling edges. Typical devices for quadrature inputs are optical encoders.
Different quadrature modes are selected based on the resolution required
by the application and the encoder used.
The module counts on the edges of the A input pulses.
When input A leads input B, the HSC counts up on each rising edge of
input A.
When input B leads input A, the HSC counts down on the falling edge
of input A.
Figure 1-5 illustrates the relationship between inputs A and B and the
count value in 1X Quadrature mode.

Handling the
Module
If there is any visible damage to the module, contact your Siemens
Industrial Automation, Inc. distributor for replacement.
Refer to the manuals listed below for instructions on installing,
programming, and troubleshooting your Series 505E controller.

Many integrated circuit (IC) devices are susceptible to damage by the
discharge of static electricity. Follow the suggestions listed below to reduce
the probability of damage to these devices when you are handling a
controller, a base controller, or any of the I/O modules.
Both the module and the person handling the module should be at the
same ground potential. To accomplish this, ensure the following.

Installation
D
The module is transported in an anti-static container or antistatic
material.
D
The work area has a conductive pad with a lead connecting it to a
common ground.

General Wiring
Considerations
The count, inhibit, and unfiltered reset inputs are high-speed inputs which
may respond to noise present on the lines. To avoid problems, follow these
guidelines when installing the HSC module.
D
Use the shortest possible wires.
D
Avoid placing signal wires parallel to high-energy wires. If the two
must meet, cross them at right angles.
D
Avoid bending the wire into sharp angles.
D
Use wireways for wire routing.
D
When using shielded wires, ground them only at the source end for
better noise immunity.
D
Place wires so that they don’t interfere with existing wiring.
D
Label the wires.
In some installations when both the HSC and TI505-49XX series of relay
modules are used, false counts may be induced when switching high
voltage in the relay module, (voltage > 40 Vrms). This is the result of
internal arcing of the relay contacts.
If you encounter this problem, place a snubber consisting of a 47 ohm 1/4
watt resistor and a 0.022 Fd capacitor across the relay contact terminals
on the terminal block. Snubbers were not included in the relay modules in
order to meet the need for lower current leakage in many applications.
: Snubber components must be ULr component recognized
and/or CSA Certified for use across the rated voltage being switched
by the relay module.

Selecting
Counter Mode
The HSC module has two channels. You can configure each channel
to operate in any of four counter modes.
Prior to installing the module into the I/O backplane, configure the module
by setting the jumper for each channel. Figure 2-2 shows the location of the
jumpers on the printed circuit board. The top set of four pins set the
counter mode for Channel 1. The bottom set of four pins set the counter
mode for Channel 2. The default setting for the jumpers is 1X Quadrature
mode for both channels.

Selecting the
Reset Filter
Some applications require faster response on the reset input line than
the standard 3.75-ms filter allows. For faster response, select the optional
0.95-ms filter. (The 0.9-ms filter is more sensitive to noisy signals, as noted
in the Environmental Specifications in Appendix B.)
The reset filter may be selected independently for each input channel by
placing the jumper in the (fast) or (slow) position as shown in
Figure 2-2.

Reset Command. Both channels have a Reset Command bit. A transition
from 0 (off) to 1 (on) of the Reset Command acts as a one-shot (providing a
momentary reset of the channel), setting the count to 0. Even though the
bit remains 1, counting resumes.
Inhibit Command. Both channels have an Inhibit Command bit. When this
bit is set to 1, the channel stops counting.
NOTE: When in the pulse counter mode, if the A or B input is in a
different state at the beginning and end of an inhibit signal, the count
will change according to the normal counting logic. If both A and B
inputs are in different states, the change may be as much as two
counts.

than the preset, the output is off.
Setting the output level bit to 1 turns the output on when the current
count is less than the preset. If the current count is greater than or
equal to the preset, the output is off.
Words WY5 through WY8 specifies preset values for each channel.
You can specify any value between 0 and 65,535.
WY5 specifies the value for Preset 1, Channel 1.
WY6 specifies the value for Preset 2, Channel 1.
WY7 specifies the value for Preset 1, Channel 2.
WY8 specifies the value for Preset 2, Channel 2.
In each scan, the controller reads the module WX words before updating
the WY words. For example, during a scan when the controller resets the
module, the WX word(s) contain counter values existing prior to the reset.

Checking the Operation of the Module
To check the operation of the module, follow these steps.
Module outputs will turn on during this procedure.
1. Using a programming device, force all presets to 0.
2. Reset both counters through the reset signals from your application.
Using the default configuration, the outputs should turn on.
3. Using your programming device, force the presets to any number
greater than 0.
The outputs should turn off.
Before resuming normal operation, clear any words that you have
forced. Otherwise, these words remain forced during operation and could
yield unexpected results.
If you used the setup word to configure the module, then the output follows
your configuration.
To check the output operation look at the counter status word (WX1), the
outputs correspond to the following bits.

Description
A reversible DC motor drives a paint sprayer up and down a vertical
assembly. A quadrature encoder on the drive shaft senses the direction and
relative position of the sprayer. Channel 1 of the HSC will be used to
enable the sprayer during a pre-defined section of travel. (See Figure 5-1.)
The encoder resolution is 500 cycles per revolution. One shaft revolution
equals 1 inch of sprayer travel. When encoder signal A leads, the direction
of travel is up.

Flow Rate Example
5.2.1
Description
5.2.2
Solution
A flow meter outputs 200 pulses per gallon. The program requires
calculation of flow rate in gallons per minute (GPM).
Configure the HSC as WX9–WX11, WY12–WY16. Attach channel 1 to the
flow meter. The HSC accumulates flow meter pulses for the duration of a
1-second fast timer. In the controller, accumulated pulses are scaled to
GPM by the following calculation (using the controller memory locations).
Equation:
GPM = Pulses per Sec Program Locations: (V23,V24) =
(WX10)
60 ? 200
(V20) ? (V19)
Following each calculation, reset the HSC, restart the Timer, and perform
a new calculation 1 second later.

Tank Filling Example
5.3.1
Description
The HSC module measures the volume of liquid and control the filling
valve. (See Figure 5-6.) A flow meter, generating 200 pulses per gallon, is
connected to the HSC channel 2, input A. Output 2 controls the filling
valve. In this example, the HSC operates in the pulse counter mode.
Solution
A count of 100,000 pulses is required to fill the tank to 500 gallons. As this
would overflow the HSC, the following RLL is used to count 10 sets of
10,000 pulses before closing the filling valve. In this program, output 1 is
used to indicate 10,000 pulses. Since the HSC runs asynchronous to the
PLC, the program accumulates overcounts for each loop and adjusts the
final loop to reach the exact count. The program utilizes the fact that the
HSC WX’s are read before the WY’s are written in an I/O cycle.
Several V memory locations are used in the program, their initial values
are:
V200
=
10,000
=
channel 2, preset 1
V201
=
30,000
=
channel 2, preset 2 initial value
V100
=
0
(overcounts will be accumulated here)
