High-performance CPU Module

The OpenNet Controller CPU module has multiple functions to work as a brain of the control system connected to the
open networks. Optimum control systems can be made possible using the OpenNet Controller.

Powerful Communication Functions

In addition to connection to the open networks, the OpenNet Controller features three more communication functions.

User Communication

Data Link

Computer Link

The OpenNet Controller can be linked to external RS232C devices such as computers,
modems, printers, and barcode readers, using the user communication function.

One OpenNet Controller at the master station can communicate with 31 slave stations
through the RS485 line to exchange data and perform distributed control effectively.

When the OpenNet Controller is connected to a computer, operating status and I/O status
can be monitored on the computer, data in the CPU can be monitored or updated, and user
programs can be downloaded and uploaded. A maximum of 32 OpenNet Controller CPUs can
be connected to one computer in the 1:N computer link system.

ONWORKS

International Safety Standards and Approvals

The OpenNet Controller is certified by UL and CSA.

Special Functions

The OpenNet Controller features various special functions packed in the small housing as described below. For details
about these functions, see the following chapters.

“Keep” or “Clear” Designation of CPU Data

Internal relays, shift register bits, counter current values, and data register values can be designated to be kept or cleared
when the CPU is powered down. All of these data or a specified range of these operands can be designated as keep or clear
types.

Catch Input Function

The catch input function makes sure to receive short input pulses (rising pulse of 40 µsec or falling pulse of 150 µsec min­imum) from sensors without regard to the scan time.

Input Filter Function

The input filter can be adjusted for the pulse widths to accept or reject input signals. This function is useful for eliminating
input noises and chatter in limit switches.

High-speed Counter Function

The OpenNet Controller has a built-in high-speed counter to make it possible to count up to 65,535 (FFFFh) high-speed
pulses which cannot be counted by the normal user program processing. The maximum count input frequency is 10 kHz.
This function can be used for simple positioning control and simple motor control.

Key Matrix Function

A matrix configuration consisting of 16 inputs and 16 outputs enables to read a maximum of 256 input signals.

User Program Read/Write Protection

The user program in the CPU module can be protected against reading and/or writing by including a password in the user
program. This function is effective for security of user programs.

Week Programmer Function

Week programmer instructions can be programmed to compare the preset date and time with the internal realtime calen­dar/clock. When the preset values are reached, designated outputs can be turned on and off as programmed for the week.

RUN/STOP Selection at Startup when “Keep” Data is Broken

When data to be kept such as “keep” designated counter values are broken while the CPU is powered down, the user can
select whether the CPU starts to run or not to prevent undesirable operation at the next startup.

Module ID Registration

Another protection method to run or stop operation is the module ID registration. When disparity is found between the
module ID registration and actual modules in the system setup, the CPU can be made to start to run or not.

User Memory Download from Memory Card

A user program can be transferred using WindLDR from a computer to a miniature memory card. The handy miniature card
can be inserted into the CPU module to download the user program. User programs can be replaced without the need for
connecting to a computer. This feature is available on CPU modules FC3A-CP2KM and FC3A-CP2SM.

Constant Scan Time

The scan time may vary whether basic and advanced instructions are executed or not depending on input conditions to
these instructions. When performing repetitive control, the scan time can be made constant by entering a required scan
time value into a special data register reserved for constant scan time.

Keep Output Status during User Program Download

Outputs can be designated to maintain the current statuses when downloading a user program from WindLDR to the CPU.
This function can be used when the output status change does not occur frequently.

Stop and Reset Inputs

Any input number can be designated as a stop or reset input to control the OpenNet Controller operation.

System Setup

This section describes various system setup configurations for using powerful communication functions of the OpenNet

Controller

Open Network Communication System

The OpenNet Controller can be connected to three open network communication lines — DeviceNet, LONWORKS, and
INTERBUS.

OpenNet interface modules are available for communication through DeviceNet and LONWORKS networks. The OpenNet
interface modules, such as DeviceNet slav e modules and LONWORKS interface modules, serv e as a sla ve station or node in
the network.

A remote I/O system can be set up using a remote I/O master module mounted next to the CPU module and SX5S commu­nication I/O terminals at remote I/O slave stations. When using 32 SX5S modules with 16 input or output points, a total of
512 I/O points can be distributed to 32 remote s lave stations at the maximum. The remote I/O network uses the INTER­BUS protocol for communication. The total cable length can be 12.8 km (7.95 miles) maximum.

Special Data Registers D8030 through D8036 (Protect Transistor Output Error)

Caution

• A prolonged overload or short circuit may damage the output circuit elements of the transistor

protect source output module. Include a protection program in the user program to protect the
output module from damage caused by overheating.

A maximum of seven transistor protect source output modules can be mounted with one CPU module. The protect output
modules are numbered from one through seven in the order of increasing distance from the CPU module. When an over­load or short circuit occurs, special data registers D8030 through D8036 store 1 to indicate the output module where the
overload occurred. D8030 through D8036 correspond to the first through seventh protect transistor modules, respectively.

When an overload or short circuit occurs, the transistor protect source output module detects the overload and shuts down
the output immediately to protect the external load and output circuit elements from permanent damage. Since the over­load detection is based on the heating of the output element, the output circuit is turned on again when the output elements
have cooled down. Consequently, a continued overloaded status causes the output to turn on and off repeatedly, and even­tually leads to deterioration of the output module.

When the cause of the short circuit is removed, the output module restores normal operation. However, once an overload
or short circuit occurs, the condition tends to continue for a long period of time. When the transistor protect source output
module is used, use of a protection program is recommended to turn off all outputs within 60 seconds as described below.

Sample Program 1: Turning All Outputs Off (when using one transistor protect source output module)

M8120 is the initialize pulse special internal relay.
MOV stores 0 to data register D8030.

output modules.
When an overload occurs, D8030 stores 1.
When the D8030 data is 1, M8002 (all outputs off special inter-

nal relay) is turned on to turn off all outputs.

Sample Program 2: Turning All Outputs Off (when using seven transistor protect source output modules)

M8120 is the initialize pulse special internal relay.
MOV stores 0 to seven data registers D8030 through D8036.
Special data registers D8030 through D8036 store protect tran-

sistor output error data when an overload or short-circuit occurs
in the first to seventh protect output modules, respectively.

When an overload occurs, D8030 through D8036 store 1.
M8125 is the in-operation output special internal relay.

Analog Input Module (A/D Converter)

The 12-bit analog input module converts 6 channels of analog signals to digital data of 0 through 4000 which can be pro­cessed using advanced instructions such as the coordinate conversion instruction. The analog input module is a functional
module and the converted digital data is stored to a link register, depending on the analog channel and the mounting slot
number of the analog input module in the system setup. The input mode can be selected using the rotary switch to meet
five different analog signal ranges; 0 to 10V, ±10V, 0 to 5V, ±5V, or 4 to 20 mA.

Example: When converting an analog voltage input (0 to 10V, ±10V, 0 to 5V, or ±5V DC) using channel 4, connect the
signal to terminals 13 and 15. When the analog input module is the second functional module installed in the

to 20 mA), connect terminals +I and +V together, and connect the input across terminals +I and COM as shown in the mid­dle above.

For wiring schematic and precautions, see page 3-8.

Notes:

• Before mounting the analog input module, first set the rotary switch to meet the required analog input range. After setting

the rotary switch, power up the CPU and other modules.

• The COM (–V, –I) terminal of each channel is independent from each other.

• Connect the +V and COM terminals of unused channels together. Connecting these terminals together will reduce the AD

conversion time in the analog input module (by approximately 10% for every unused slot).

Wiring Example:

Suppose that an analog output module is the sixth functional module installed in the

OpenNet Controller system. To gener-

ate a 4V analog output voltage from channel 1 using the 0 to 5V output range, set the rotary switch to 2 and store a digital
value of 3200 to link register L601, which is assigned to channel 1 of the sixth functional module.

Because 5V × 3200/4000 = 4V, digital value 3200 is converted to an analog value of 4V and outputted to terminals 15 and
16 of the analog output module.

For wiring schematic and precautions, see page 3-8.

Notes:

• Before mounting the analog output module, first set the rotary switch to meet the required analog output range. After set-

ting the rotary switch, power up the CPU and other modules.

• The COM (GND) terminals of each channel are connected together internally.

Introduction

This chapter describes the methods and precautions for installing and wiring OpenNet Controller modules.
Before starting installation and wiring, be sure to read “Safety Precautions” in the beginning of this manual and under-

stand precautions described under Warning and Caution.

Warning

Caution

• Turn power off to the

nance, and inspection of the OpenNet Controller. Failure to turn power off may cause electrical
shocks or fire hazard.

• Emergency stop and interlocking circuits must be configured outside the OpenNet Controller. If

such a circuit is configured inside the OpenNet Controller, failure of the OpenNet Controller may
cause disorder of the control system, damage, or accidents.

• Special expertise is required to install, wire, program, and operate the OpenNet Controller. People

without such expertise must not use the OpenNet Controller.

Installation Location

The OpenNet Controller must be installed correctly for optimum performance.
The environment for using the OpenNet Controller is “Pollution degree 2.” Use the OpenNet Controller in environments of

pollution degree 2 (according to IEC 60664-1).
Make sure that the operating temperature does not drop below 0°C or exceed 55°C. If the temperature does exceed 55°C,

use a fan or cooler.
Mount the OpenNet Controller on a vertical plane.
To eliminate excessive temperature build-up, provide ample venti-

lation. Do not install the OpenNet Controller near, and especially
above, any device which generates considerable heat, such as a
heater, transformer , or lar ge capacity resistor. The relative humidity
should be above 30% and below 95%.

The OpenNet Controller should not be exposed to excessive dust,
dirt, salt, direct sunlight, vibrations, or shocks. Do not use the

OpenNet Controller in an area where corrosive chemicals or flam-

mable gases are present. The modules should not be exposed to
chemical, oil, or water splashes.

Caution

• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.

• The allowable power voltage range for the OpenNet Controller is 19 to 30V DC. Do not use the

OpenNet Controller on any other voltage.

• If the power voltage turns on or off very slowly between 5 and 15V DC, the OpenNet Controller

may run and stop repeatedly between these voltages. If failure or disorder of the control system,
damage, or accidents may be caused, provide a measure for prevention using a voltage monitor­ing circuit outside the OpenNet Controller.

• Use an IEC 60127-approved fuse on the power line outside the OpenNet Controller. This is

required when exporting equipment containing OpenNet Controller to Europe.

Power Supply Voltage

The allowable power voltage range for the

OpenNet Controller is 19 to 30V DC.

Power failure detection voltage depends on the quantity of used input and output points. Basically, power failure is
detected when the power voltage drops below 19V DC, stopping operation to prevent malfunction.

A momentary power interruption for 10 msec or less is not recognized as a power failure at the rated voltage of 24V DC.

Inrush Current at Powerup

When the

OpenNet Controller is powered up, an inrush current of 40A or

less flows at the rated voltage of 24V DC.

Power Supply Wiring

Use a stranded wire of UL1015 AWG22 or UL1007 AWG18 for power
supply wiring. Make the power supply wiring as short as possible.

Run the power supply wiring as far away as possible from motor lines.

Keep Designation for Internal Relays, Shift Registers, Counters, and Data Registers

The statuses of internal relays and shift register bits are usually cleared at startup. It is also possible to designate all or a
block of consecutive internal relays or shift register bits as “keep” types. Counter current values and data register values
are usually maintained at powerup. It is also possible to designate all or a block of consecutive counters and data registers
as “clear” types.

When the CPU is stopped, these statuses and values are maintained. When the CPU is reset by turning on a designated
reset input, these statues and values are cleared despite the settings in the Keep dialog box shown below. The keep/clear
settings in this dialog box have effect when restarting the CPU.

Since these settings relate to the user program, the user program must be downloaded to the OpenNet Controller after

Input Filter

The input filter function is used to reject input noises. The catch input function described in the next section is used to
receive short input pulses. On the contrary, the input filter function ignores short input pulses when the OpenNet Controller
is used with input signals containing noises.

Normal inputs require a pulse width of the filter value plus one scan time to receive input signals. Input filter values have
effect on the performance of the catch inputs, key matrix inputs, and digital read instruction.

Since these settings relate to the user program, the user program must be downloaded to the OpenNet Controller after
changing any of these settings.

High-speed Counter

This section describes the high-speed counter function to count many pulse inputs within one scan. Using the built-in 16­bit high-speed counter, the OpenNet Controller counts up to 65535 high-speed pulses from a rotary encoder or proximity
switch without regard to the scan time, compares the current value with a preset value, and turns on the output when the
current value exceeds the preset value. This function can be used for simple motor control or to measure lengths of objects.

The high-speed counter can be used in the rotary encoder mode or dual-pulse reversible counter mode, which can be
selected using the Function Area Settings in WindLDR.

The CPU module has screw terminals 1 through 5 dedicated to the high-speed counter. The high-speed counter counts up
or down input pulses to terminals 2 (phase A or CW) and 3 (phase B or CCW), and turns on the comparison output at ter­minal 5 (comparison output) when the current value exceeds the preset v alue. The comparison output does not go on when
the preset value is reached, but goes on when another input pulse enters after reaching the preset v alue. Use of the compar ­ison output is selected using the Function Area Settings.

When the input to terminal 4 (phase Z or reset-to-zero input) is turned on, the current value is reset to zero.
Three special data registers and seven special internal relays are assigned to control and monitor the high-speed counter

operation. The high-speed counter current value is stored in data register D8045 and is updated every scan. The value
stored in D8046 is used as a reset value, and the value in D8047 is used as a preset v alue to compare with the current v alue.
When a high-speed counter reset input (described later) is turned on, the current value in D8045 is reset to the value stored
in D8046 and the high-speed counter counts subsequent input pulses starting at the reset value.

When comparison output reset special internal relay M8010 is turned on, the comparison output is turned off. While the
high-speed counter is counting up, up/down status special internal relay M8130 remains on. While counting do wn, M8130
remains off. When the current v alue exceeds the preset value, comparison ON status special internal relay M8131 turns on
in the next scan. When the current value is reset (cleared) to zero, current value zero-clear special internal relay M8132
turns on in the next scan. When a current value overflow or underflow occurs while counting up or down, special internal
relay M8133 or M8134 turns on in the next scan, respectively. While the comparison output is on, comparison output sta­tus special internal relay M8135 remains on. While the comparison output is off, M8135 remains off. See page 5-12.

In addition, two inputs can be designated as a high-speed counter gate input and reset input to control the high-speed
counter operation. The gate input and reset input are designated using the Function Area Settings. When a gate input is
designated, counting is enabled while the gate input is on and is disabled while the gate input is off. When a gate input is
not designated, counting is always enabled. When the reset input is turned on, the current value is reset to the reset value.

Example: Counting High-speed Input Pulses from Rotary Encoder

This example demonstrates a program to punch holes in a paper tape at regular intervals.

Description of Operation

A rotary encoder is linked to the tape feed roller directly, and
the output pulses from the rotary encoder are counted by the
high-speed counter in the OpenNet Controller CPU module.
When the high-speed counter current value reaches 3,000, the
comparison output is turned on. When the comparison output is
turned on, the current value is reset to 300 automatically to
continue another cycle of counting. The comparison output
remains on for 0.5 second to punch holes in the tape, and is
turned off until the preset value is reached again.

Key Matrix Input

The key matrix input function can be programmed using the Function Area Settings in WindLDR to form a matrix with 1 to
16 input points and 1 to 16 output points to multiply input capability. A key matrix with 8 inputs and 4 outputs would equal
32 inputs, for example. The maximum, 16 inputs and 16 outputs, would result in 256 input points.

The input information is stored in consecutive internal relays as many as the quantity of input points multiplied by the
quantity of output points, starting at the first internal relay number programmed in the Function Area Settings.

When using the key matrix input function, DC input modules and transistor output modules must be used.
Since these settings relate to the user program, the user program must be downloaded to the OpenNet Controller after

changing any of these settings.

Memory Card

A user program can be stored on a miniature memory card from a computer running WindLDR and downloaded to the

OpenNet Controller CPU module without using a computer. This feature is available on FC3A-CP2KM and FC3A-

CP2SM only.
Using a memory card, the user program in the CPU module can be replaced where WindLDR or a computer cannot be used.
Depending whether a memory card is installed in the OpenNet Controller CPU module or not, a user program stored on

the memory card or in the CPU is executed, respectively.

Memory Card User Program
Installed in the CPU The user program stored on the memory card is executed.
Not installed in the CPU The user program stored in the flash ROM in the CPU module is executed.

Caution

• When the user program is downloaded from the memory card to the CPU, the user program

stored in the flash ROM in the OpenNet Controller CPU module is overwritten.

• Power down the CPU before inserting or removing the memory card.

• Program execution using the memory card must be limited to operation check only. Do not use

the memory card for normal execution of user programs.

Downloading User Program from Memory Card to the CPU

1. Power down the

OpenNet Controller CPU module.

2. Insert a memory card into the CPU module until the card clicks into place as shown at right.

3. Power up the CPU module. The CPU starts to run the user program stored on the memory card.

Constant Scan Time

The scan time may vary whether basic and advanced instructions are executed or not depending on input conditions to
these instructions. The scan time can be made constant by entering a required scan time preset value into special data reg­ister D8022 reserved for constant scan time. When performing accurate repetitive control, make the scan time constant
using this function. The constant scan time preset value can be between 1 and 1,000 msec.

The scan time error is ±1 msec of the preset value normally. When the data link or other communication functions are
used, the scan time error may be increased to several milliseconds.

When the actual scan time is longer than the scan time preset value, the scan time cannot be reduced to the constant value.

Special Data Registers for Scan Time

In addition to D8022, three more special data registers are reserved to indicate current, maximum, and minimum scan time
values.

D8022 Constant Scan Time Preset Value (1 to 1,000 msec)
D8023 Scan Time Current Value (msec)
D8024 Scan Time Maximum Value (msec)
D8025 Scan Time Minimum Value (msec)

Example: Constant Scan Time

This example sets the scan time to a constant value of 500 msec.

M8120 is the initialize pulse special internal relay.
When the CPU starts operation, the MOV (mov e) instruction sets 500 to
special data register D8022.
The scan time is set to a constant value of 500 msec.

Introduction

This chapter describes allocation numbers available for the OpenNet Controller CPU module to program basic and
advanced instructions. Special internal relays and special data registers are also described.

The OpenNet Controller is programmed using operands such as inputs, outputs, internal relays, timers, counters, shift reg­isters, data registers, and link registers.

Inputs (I) are relays to receive input signals through the input terminals.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Internal relays (M) are relays used in the CPU and cannot be outputted to the output terminals.
Special internal relays (M) are internal relays dedicated to specific functions.
Timers (T) are relays used in the user program, available in 1-sec, 100-msec, 10-msec, and 1-msec timers.
Counters (C) are relays used in the user program, available in adding counters and reversible counters.
Shift registers (R) are registers to shift the data bits according to pulse inputs.
Data registers (D) are registers used to store numerical data. Some of the data registers are dedicated to special functions.
Link registers (L) are registers used for inputting and outputting numerical values to and from functional modules.
