Operation Examples of Zero Suppression

Zero suppression operates when the display is 0, RBI is low, and the decimal

point is not lit. Then low is output to RBO.

Example 1: Zero suppression is not required and the RBI input and RBO

output of each digit are open.

Example 2: Zeros are suppressed only for the digits on the left of the digit

where the decimal is lit when both zero suppression and a

decimal point are being used.

Note: Use RBO output for the connection with RBI input only.

Note: Use separate output terminals for DP

or BI control.

Dynamic Control

Connected to C200H-OD215 (Static Mode) Transistor Output Unit

•Connect the PLC's output to the A to D (BCD

output) terminals of the rightmost digit.

•Latch control is set with the LE1 to LE4 terminals of

the rightmost Unit.

The terminals correspond as follows:

LE1: Rightmost digit (example: 1's digit)

LE2: Second digit (example: 10's digit)

LE3: Third digit (example: 100's digit)

LE4: Forth digit (example: 1,000's digit)

Note: 1. The display colors of the three-color displays must be selected individually.

2. In static mode, ladder programming is required for latch control.

3. If the cycle time of the PLC is too short, its relationship with the ON/OFF

response time of the M7E may not work well. Set a minimum cycle time or

otherwise adjust the cycle time accordingly.

4. The reception of orders for C200H-OD215 was discontinued at the end of

March 2017.The recommended replacements are the CS1W-OD231 and

CJ1W-OD231, but they not Dynamic Output Units. Therefore, ladder

programming will be required to use them as replacements.

B7A Link Terminal •By supplying power to a single display, all the displays will be

supplied with power.

•The B7A's serial output must be connected to the SI terminal of

the rightmost TB1.

•Use OMRON's M7E-WH@11A Harness Connectors or

equivalent to connect all Units.

•The DP and BI terminals can be controlled by transmitting the

following special data

Hexadecimal C data: Turns ON the decimal point of the relevant

digit.

Hexadecimal D data: Turns OFF the decimal point of the

relevant digit.

Hexadecimal F data: Deletes the display (BI control) of the

relevant digit.

•Use the B7A Link Terminal with a normal I/O delay of 19.2 ms.

The B7A with short I/O delay cannot be used.

Note: The display colors of the three-color displays must be selected individually.

■Serial Transmission with B7A Link Terminal

A series of models incorporating a communications (serial transmission) function is available.

By using the B7A Link Terminal (PLC connector model), the Units can be connected to the PLC with ease. The 16-point B7A Link Terminal allows

the control of a maximum of four digits over two wires.

Available Link Terminal Models

Transmission Path

Transmission distance:

A maximum transmission distance of 500 m is

possible by using the VCTF 0.75 x 2C Cable if

power is supplied independently to the Input and

Output Link Terminals.

A maximum transmission distance of 100 m is

possible by using the VCTF 0.75 x 3C Cable if a

single pow er supply is connected to the Input or

Output Link Terminal, in which case the current

flow on the power lines (positive and negative

lines) is 1.8 A maximum.

Transmission delay:

A maximum of 50 ms for data display after the

B7A's input signal becomes definite.

Minimum Input Time

Use an input time of 80 ms min. to the Input

Unit for the B7A.

Signal Allocation

B7A-M7E Corresponding Pin List

The B7A's switch terminals correspond to the

M7E's parallel input signals as follows:

Note: A maximum of two Display Units can be

connected when the 10-point B7A Link

Terminal is used and a maximum of four

Display Units can be connected when the

16-point B7A Link Terminal is used.

Errors

1. No signal transmission is available due to the

disconnection of the transmission path (the SI

or GND wire).

2. The waveform is greatly distorted due to

ex ternal noise interference or because the

transmission path is longer than the

permissible transmission path.

Error Indication

When an error results, “-” will be displayed and

the display will flash. After the condition returns to

normal, reception data will be displayed.

Display after Error

Correction

After the condition returns to normal, the display

will be reset automatically and reception data will

be displayed.

•The short-circuit socket is short circuited at the factory (i.e., normally lit). Open the short-circuit

socket if external control or lighting are not required

Zero Suppression Control

•When the z ero suppre ssio n funct ion is not u se d, the RB I (J9 ) terminals mu st b e o pen. The TER

(J11) terminals can be either short-circuited or open.

•When zero suppre ssio n i s not used, the RBI (J9) terminals of the M7E Digital Display Unit for

the leftmost digit must be short-circuited, those of all the other M7E Digital Displa y Units m ust be

open, the TER (J11) terminals of the M7E Digital Display Unit for the rightmost digit must be

open, and those of all the other M7E Digital Display Units must be shor t-circuited.

Example of Zero Supp r ession Setting for Four Digits on the M7E (120/

200-mm Model)

Note: To use zero suppression, CN2 and CN3 must be connected with an M7E-

WH@11A Harness Connector.

In static mode, ladder programming is required for latch control. If latch control

is not used, cut the data I/O lines (pins 1 to 4) on the Harness Connector.

Display Color Contr ol (Three-color Model Only)

•Short-circuit the R (J8) terminals with a short-circuit socket so that the display will be lit in red.

•Short-circuit the G (J10) terminals with a short-circuit socket so that the display will be lit in

green.

•Short-circuit the R (J8) as well as G (J10) terminals with two short-circuit so ckets so that the

display will be lit in orange.

Note: When the R (J8) as well as G (J10) terminals are open, the display will be OFF if the CN1

Input Connector has not been connected yet.

Note: 1. All the terminals are short-circuited before shipping. Short-circuit or open the terminals according

to the application.

2. Single-color (red or green) models do not incorporate the R (J8) and G (J10) terminals.

3. These terminals must be open when controlling the DP (J5), R (J8), and G (J10) terminals

externally by inputting signals from the CN1. (The short-circuit socket will take precedence.)

4. All the terminals J5 to J11 are connected to GND.

5. The 80-mm Model uses DIP switches. ON: Short-circuited OFF: Open

(SEL1 and SEL2 are switches to adjust brightness.)

80-mm Model

M7E

■Zero Suppression

To use zero suppression, first connect the CN3 and CN2 connectors on the M7E to the M7E-WH@11A Harness Connector.

Then, set the DIP s witch on the M7E-08@ (80-mm model) or short the required pins with short-circuit sockets on the M7E-12@ (80-mm model) or

M7E-20@(200-mm model).

Zero Suppression for 80-mm Models

To use zero suppression, turn ON the RBI and TER pins on the DIP

switch on the M7E for the most-significant digit, turn OFF the RBI

and TER pins on the DIP switch on the M7E for the least-significant

digit, and then turn the RBI pin OFF and the TER pin ON on the DIP

switches on the M7E for the other digits.

To use zero suppression, CN2 and CN3 must be connected with the

M7E-WH@11A Harness Connector.

In static mode, ladder programming is required for latch control. If latch

control is not used, cut the data I/O lines (pins 1 to 4) on the Harness

Connector.

Example of Zero Suppression Setting for Four Digits on

the M7E (80-mm Model)

Zero Suppression for 120/200-mm Models

To use zero suppression, short-circuit the RBI and TER pins with the

short-circuit sockets on the M7E for the most-significant digit, and

leave these pins open on the M7E for the least-significant digit. For

the M7E for other digits, leave the RBI pin open and short-circuit the

TER pin.

By removing the rear cover of the Display Unit and setting the XJ8A-

0211 Short-circuit Socket, the following control operations are

possible.

To use zero suppression, CN2 and CN3 must be connected with the

M7E-WH@11A Harness Connector.

In static mode, ladder programming is required for latch control. If latch

control is not used, cut the data I/O lines (pins 1 to 4) on the Harness

Safety Precautions

■Precautions for Correct Use

Environment

•Use the switches in locations that are not subject to organic

solvents (thinner , benz ene, etc.), strong alkali, strong acid, sunlight,

corrosive gases, water, and oil.

•Use the units in areas not subject to vibration or shoc k in excess of

specifications.

Wiring

•When wiring with terminals or a connector, remove the rear cover

of the M7E and connect the M7E to the terminals or connector

properly, and be sure not to leave any wire cuttings inside the

Display Unit.

•Make sure that no wire is more than five meters long when wiring

the B7A link terminal.

Mounting

When mounting Display Units to a box, make slits on the rear part

and the top of the box for ventilation. If there is no proper ventilation,

the life of each Display Unit may be shortened.

Connecting Cable

When connecting an XG4M-2030 or XG4M-2030-T G79 Cable to a

Digital Display with 80-mm-high Characters, an XG4Z-0002 Lock

Lever can be used.
