Glossary
A
Analog potentiometer
It can be used to preset a value for an analog timer. All Modular controllers and
Compact 10 and 16 I/O controllers have one analog potentiometer. The Compact 24
I/O controller has two:
Analog Voltage Input Connector
Connects an analog voltage source of 0 through 10 VDC. The analog voltage is converted to a discrete value and is stored in a system word.
C
CAN
Cartridge Connector
A connector to attach an optional memory cartridge or an RTC.
Catch Input
Controller Area Network : field bus originally developed for automobile applications which is now used in many sectors, from industrial to tertiary.
Verify that you are receiving short input pulses (rising pulse of 40 μ s or falling pulse of 150 μ s minimum) from sensors without regard to the scan time.

233
Glossary
CiA
CAN in Automation : international organization of users and manufacturers of CAN products.
COB
Communication OBject : transport unit on CAN bus. A COB is identified by a unique identifier, which is coded on 11 bits, [0, 2047]. A COB contains a maximum of 8 data bytes. The priority of a COB transmission is shown by its identifier - the weaker the identifier, the more priority the associated COB has.
Communication Adapter
An optional cartridge that can be attached to any Compact controller or Operator
Display Expansion Module to provide an optional Serial Port 2.
Communication Expansion Module
An optional module that can be attached to any Modular controllers communications expansion bus to provide an optional Serial Port 2.
Controller status output
A special function. This function is used in circuits, external to the controller, to control the power supply to the output devices or the controller power supply.
E
EDS
Electronic Data Sheet : description file for each CAN device (provided by the manufacturers).
ERR LED
An LED that illuminates when a detected error is detected in the controller.
Expansion connector
A connector to attach expansion I/O modules.
Expansion Connector Cover
A cover to protect the expansion connector.
234 35011387 06/2011
Glossary
Expansion I/O Module
Either a discrete or analog module that adds additional I/O to the base controller.
F
Fast Counting
A special function, it is available as a single up counter and single down counter.
These functions enable up counting or down counting of pulses (rising edges)on a discrete I/O. Compact controllers can be equipped with three fast counters. Modular controllers can have two fast counters.
Free Wire
I
The end of a discrete I/O cable whose wires do not have a connector. This scheme provides connectivity from Modular I/O to discrete I/O points.
I/O
Input/Output.
I/O terminals
Terminals on all Modular controllers and expansion I/O modules used to connect input and output signals. The input terminals accept both sink and source DC input signals. The output terminals are either transistor source or sink or relay contacts.
IN LED
An LED that illuminates when a corresponding input is on. All modules have IN
LEDs.
Input Filter
A special function that rejects input noises. This function is useful for addressing input noises and chatter in limit switches. All inputs provide a level of input filtering using the hardware. Additional filtering using the software is also configurable through TwidoSuite.
35011387 06/2011
235
Glossary
Input Simulators
An optional accessory for Compact controllers that is used for debugging. It can simulate input sensors to test application logic.
Input terminals
Terminals on the top of all Compact controllers used to connect input signals from input devices such as sensors, push buttons, and limit switches. The input terminals accept both sink and source DC input signals.
L
Latching input
A special function. This function is used to memorize any pulse with a duration less than the controller scan time. When a pulse is shorter than one scan and has a value greater than or equal to 100 μ s, the controller latches the pulse, which is then updated in the next scan.
M
Memory Cartridge
An optional cartridge available in two sizes: 32 KB and 64 KB (64 KB not available on Compact). It can be added to any controller for removable backup of applications or to load an application, if certain conditions exist. The 64 KB cartridge is also used to increase program memory.
Modbus Master Mode
Allows the controller to initiate a Modbus query transmission, with a response expected from a Modbus slave.
Modbus Slave Mode
Allows the controller to respond to Modbus queries from a Modbus master and is the default communications mode if no communication is configured.
236 35011387 06/2011
Glossary
O
Operator display expansion module
An optional module that can be attached to any Modular controller to display program information.
Operator display module
An optional module that can be attached to any Compact controller to display program information.
OUT LED
An LED that illuminates when a corresponding output is on. All modules have OUT
LEDs.
Output terminals
Terminals on the bottom of all Compact controllers used to connect output signals from output devices such as electromechanical relays and solenoid valves. The internal output relay contact is rated up to 240 VAC/2A or 30 VDC/2A.
P
PLS
Power Supply Terminals
The power supply is connected to these terminals to provide power to the controller.
The power voltage for a Compact controller is 100-240 VAC and 24 VDC for a
Modular controller.
PWM
A special function. This user-defined function block generates a signal on output
%Q0.0.0 or %Q0.0.1. This signal has a variable period but has a constant duty cycle, or on to off ratio of 50% of the period.
A special function. This user-defined function block generates a signal on output
%Q0.0.0 or %Q0.0.1. This signal has a constant period with the possibility of varying the duty cycle, or on to off ratio.

Glossary
PWR LED
An LED that illuminates when power is supplied to the controller.
R
Removable Cover
A cover on all Compact controllers that can be removed to install an optional
Operator Display.
RTC
Real Time Clock.
RTD
Temperature detector of type PT100, PT1000 etc. Resistor Temperature Detector.
RUN LED
An LED that illuminates when the controller is executing a program.
S
Sensor power terminals
Supplies power to the sensors (24 VDC, 400 mA for -40DRF compact controllers and 250 mA for all other controllers). Output terminals are only intended for input devices and not be used as a source for driving external loads.
Serial Port 1
An EIA RS-485 connector used to download and monitor the controller operation using TwidoSuite.
Serial port 2
An optional port that can be configured as either EIA RS-232 or EIA RS-485.
STAT LED
An LED that blinks on and off to indicate a specific status of the user program.

Glossary
T
Terminal cover
A cover on all Compact controllers to protect the input and output terminals.
V
Very Fast Counting
A special function available as an up/down counter, an up/down 2-phase counter, a single up counter, a single down counter, and frequency meter. The counter functions enable counting of pulses from 0 to 65,535 in single-word mode and from
0 to 4,294,967,295 in double-word mode. The frequency meter function measures the frequency of a periodic signal in Hz.
