CX1010-N030/40 connections
The CX1010-N030 system interface features two RS232 interfaces, COM1 and COM2 (9 pin Sub-D plug connector). If there is need for more than two serial interfaces two further RS232 interfaces, COM3 and COM4 (9 pin Sub-D plug connector) can be added to the system via the system interface CX1010-N40. The maximum baud rate on all channels is 115 kBit. The pin assignment for all interfaces is equal and described below. The interface parameter can be set in the operating system or in the PLC program.
RS232 COM interface (connector):
PIN | Signal | Type | Description |
---|---|---|---|
1 | DCD | Signal in | Data Carrier Detected |
2 | RxD | Signal in | Receive Data |
3 | TxD | Signal out | Transmit Data |
4 | DTR | Signal out | Data Terminal Ready |
5 | GND | Ground | Ground |
6 | DSR | Signal in | Dataset Ready |
7 | RTS | Signal out | Request to Send |
8 | CTS | Signal in | Clear to Send |
9 | RI | Signal in | Ring Indicator |
The system interface CX1010-N30 can only be used instead and not simultaneously with system interface CX1010-N031. The system interface CX1010-N40 can only be used instead and not simultaneously with system interface CX1010-N041. |
