M7E
CSM_M7E(80_120_200mm)_DS_E_10_2
Digital Display with Wire-saving Serial
Transmission Function (B7A Output)
• Single-color (red or green) and three-color (red, green, or
orange selectable) displays with a character height of 80, 120,
or 200 mm are available for a variety of applications and
locations.
• Thin design with a 39.5-mm depth for the 120-mm model is
perfect for saving space in equipment and devices.
• Decimal display including negative sign (−) display with signal
codes is possible.

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.

PLC Connections
Refer to your PLC operation manual before connecting the PLC.
Static Control
Connected to C500-OD213 Transistor Output Unit

A to D,
DP, BI
Connect the PLC's output to the A to D (BCD
output), DP, and BI terminals individually.
Note: Use separate output terminals for DP
or BI control.
Dynamic Control
Connected to C200H-OD215 (Static Mode) Transistor Output Unit
PLC
A to D,
DP, LE
• 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)
Harness connector
LE3: Third digit (example: 100's digit)
[email protected]
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.

OUTPUT UNIT
(BCD output)
• 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 [email protected] 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

■ 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.

Transmission Path
Signal Allocation
Errors
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 power 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.
B7A-M7E Corresponding Pin List
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
external noise interference or because the
transmission path is longer than the
permissible transmission path.
Minimum Input Time
Use an input time of 80 ms min. to the Input
Unit for the B7A.
The B7A's switch terminals correspond to the
M7E's parallel input signals as follows:

■ A Variety of Control Operations with Short-circuit Sockets
By removing the rear cover of the Display Unit and setting the XJ8A-0211 Short-circuit Socket, the following control operations are possible.
1. DP (J5)
2. RBI (J9)
TER (J11)
Decimal Control
• Short-circuit the DP (J5) terminals with a short-circuit socket so that the decimal point will be
always lit.
• 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
Short-circuit
socket
Zero Suppression Control
• When the zero suppression function is not used, the RBI (J9) terminals must be open. The TER
(J11) terminals can be either short-circuited or open.
• When zero suppression is 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 Display Units must 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 short-circuited.
Example of Zero Suppression Setting for Four Digits on the M7E (120/
200-mm Model)
Note: To use zero suppression, CN2 and CN3 must be connected with an [email protected] 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.

■ Zero Suppression
To use zero suppression, first connect the CN3 and CN2 connectors on the M7E to the [email protected] Harness Connector.
Then, set the DIP switch 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
Zero Suppression for 120/200-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, 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.

Safety Precautions
■ Precautions for Correct Use
Environment
• Use the switches in locations that are not subject to organic
solvents (thinner, benzene, etc.), strong alkali, strong acid, sunlight,
corrosive gases, water, and oil.
• Use the units in areas not subject to vibration or shock 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.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
In the interest of product improvement, specifications are subject to change without notice.
