Chapter 2 2.1 Using the Serial Interface DX Features 1 Serial communication can be performed using RS-232 or RS-422/485. Explains the serial communication functions. • The DX can connect to a Modbus slave device and read or write to the internal register. The read data can be used as communication input data of the computation function* on a computation channel. The data can also be handled on the external input channel.
2.1 DX Features Modbus Slave • A Modbus master device can carry out the following operations on the DX that is operating as a Modbus slave device.
2.2 Flow of Operation When Using the Serial Interface 1 The flow chart below shows the procedure to set the communication using RS-232 or RS-422/RS-485. The procedure varies for RS-232 and RS-422/RS-485.
2.3 Connecting the DX Connecting the cable Connect a cable to the serial port on the DX rear panel. RS-232 Connection Procedure Connect a cable to the 9-pin D-sub RS-232 connector. Connector pin arrangement and signal names 2 1 3 4 5 (Rear panel) 6 7 8 9 Each pin corresponds to the signal indicated below. The following table shows the signal name, RS-232 standard, JIS, and ITU-T standard signals.
2.3 Connecting the DX 1 • Connection example • OFF-OFF/XON-XON PC PC SD RD RS CS SG SD RD RS CS SG 3 2 7 8 5 DX SD RD RS CS SG 2 • XON-RS(XON-RTS) PC SD RD RS CS SG 3 2 7 8 5 DX SD RD RS CS SG Using the Serial Interface 3 2 7 8 5 SD RD RS CS SG • CS-RS(CTS-RTS) DX 3 The connection of RS on the PC and CS on the DX is not necessary. However, we recommend that you wire them so that the cable can be used in either direction.
2.3 Connecting the DX • XON-XON • Data transmission control Software handshaking is performed between the DX and the PC. When an “X-OFF” code is received while sending data to the PC, the DX stops the data transmission. When the DX receives the next “X-ON” code, the DX resumes the data transmission. The CS signal received from the PC is ignored. • Data reception control Software handshaking is performed between the DX and the PC.
2.3 Connecting the DX 1 RS-422/485 Connection Procedure Terminal arrangement and signal names Connect a cable to the clamp terminal. 2 Using the Serial Interface (rear panel) FG SG SDB RDB SDA RDA 3 Each terminal corresponds to the signal indicated below. Signal Name FG SG SDB SDA RDB RDA Meaning Frame ground of the DX. Signal ground. Send data B (+). Send data A (–). Receive data B (+). Receive data A (–).
2.3 Connecting the DX Connection example to the host device A connection can be made with a host device having a RS-232, RS422, or RS-485 port. In the case of RS-232, a converter is used. See the connection examples below for a typical converter terminal. For details, see the manual that comes with the converter.
2.3 Connecting the DX Note • 1 2 Using the Serial Interface • The method used to eliminate noise varies depending on the situation. In the connection example, the shield of the cable is connected only to the DX’s ground (one-sided grounding). This is effective when there is a difference in the electric potential between the computer’s ground and the DX’s ground. This may be the case for long distance communications.
