Chapter 3 Using the Serial Interface 3.1 1 Workflow for Using the Serial Interface The flow chart below shows the procedure to set RS-232 or RS-422/RS-485 communication. The procedure differs between RS-232 and RS-422/RS-485.
3.2 Connecting the MV Connecting a Cable Connect a cable to the serial port on the MV rear panel. RS-232 Connection Procedure Connect a cable to the 9-pin D-sub RS-232 connector. Connector Pin Arrangement and Signal Names 1 2 3 4 5 (Rear panel) 6 7 8 9 Pin assignments are shown in the table below. The table shows the signal names as defined by the RS-232 , JIS, and ITU-T standards along with their description.
3.2 Connecting the MV 1 • Connection example • OFF-OFF/XON-XON PC 3 2 7 8 5 SD RD RS CS SG • CS-RS (CTS-RTS) PC MV MV SD RD RS CS SG SD RD RS CS SG 3 2 7 8 5 SD RD RS CS SG 2 • XON-RS (XON-RTS) PC 3 2 7 8 5 MV SD RD RS CS SG 3 You do not need to wire RS on the PC to CS on the MV. However, we recommend it so that the cable can be used in either direction.
3.2 Connecting the MV • XON-XON • Data transmission control Software handshaking is performed between the MV and the PC. When an “X-OFF” code is received while sending data to the PC, the MV stops the data transmission. When the next “X-ON” code is received, the MV resumes transmission. The MV ignores the CS signal that is received from the PC. • Data reception control Software handshaking is performed between the MV and the PC.
3.2 Connecting the MV 1 RS-422/485 Connection Procedure Terminal Arrangement and Signal Names Connect a cable to the clamp terminal. 2 (Rear panel) FG SG SDB RDB SDA RDA 3 Using the Serial Interface Terminal assignments are shown in the table below. Signal Name FG (Frame Ground) SG (Signal Ground) SDB (Send Data B) SDA (Send Data A) RDB (Received Data B) RDA (Received Data A) Signal Description The MV case ground. Signal ground. Send data B (+). Send data A (–). Receive data B (+).
3.2 Connecting the MV Example of a Connection to the Host Device The MV can connect to a host device that has an RS-232, RS422, or RS-485 port. If the host device has an RS-232 port, use a converter. See the examples below for typical converter terminals. For details, see the converter manual.
3.2 Connecting the MV Note • • The way to eliminate noise varies depending on the situation. In the connection example, the cable shield is connected only to the MV’s ground (one-sided grounding). This is effective when there is a difference in the electric potential between the PC’s ground and the MV’s ground, which may be the case with long distance communications.
3.3 Configuring the Serial Interface ◊ Press MENU and then select Menu tab > Basic setting mode > Menu tab > Communication (Serial) > Basic settings For RS-232 • Baud rate Select 0, 1200, 2400, 4800, 9600, 19200, or 38400 (bps). • Data length Select 7 or 8 (bits). To output the data in binary format, select 8. • Parity Set the parity to Odd, Even, or None. • Handshaking Select Off:Off, XON:XON, XON:RS, or CS:RS. • Address Enter a value in the range of 1 to 99 for the Modbus protocol.
3.4 Reading/Writing the MV Data from Another Device via Modbus 1 2 The MV is a Modbus slave. For Modbus specifications, see section 7.3. Configuring the Serial Interface 3 Set Protocol to Modbus under Serial basic settings. See section 3.3 for details. Another device (master device) sends commands to the MV to read data from the MV or write data to the MV. For the function codes that the MV supports and the MV registers that the master device can access, see “Modbus Server Function” in section 7.3.
3.5 Reading/Writing Data on Another Device from the MV via Modbus The MV is a Modbus master. For Modbus specifications, see section 7.3. Configuring the Serial Interface Set Protocol to Master-M under Serial basic settings. See section 3.3 for details.
