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 CS1W-OD261 and CJ1W-OD231 Transistor Output Unit PLC 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 Note: 1. 2. 3. 4. * 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) M7E-WH@11A LE4: Forth digit (example: 1,000's digit) The display colors of the three-color displays must be selected individually. In static mode, ladder programming is required for latch control. 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. 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 Harness connector following special data M7E-WH@11A 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. PC OUTPUT UNIT The B7A with short I/O delay cannot be used. (BCD output) Note: The display colors of the three-color displays must be selected individually. Connected to CS1W-OD211 and CJ1W-OD211 Transistor Output Unit 5 M7E 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.

For details on corresponding models, refer to each applicable model's catalog. 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: B7A switch terminal M7E parallel input A0 A1 A2 A3 First digit (1's digit) A B C D A4 A5 A6 A7 Second digit (10's digit) A B C D A8 A9 A10 A11 Third digit (100's digit) A B C D A12 A13 A14 A15 Fourth digit (1000's digit) A B C D 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. 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. 6 M7E Serial Transmission Control Examples 1. 1234 is displayed. 5. 4.2-1 is displayed.

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 M7EWH@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.

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.

By removing the rear cover of the Display Unit and setting the XJ8A0211 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 Connector. To use zero suppression, CN2 and CN3 must be connected with the M7E-WH@11A Harness Connector.

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.
