Can communicate with devices such as barcode readers (RS232C) and network inverters (RS485) using RS232C and RS485
Row data input and output, ASCII and HEX (binary) communication can be achieved through radar programs.
OEMAX-NX700-UM009A-KO-P-Serial communication unit
Unit is equipped with dual channels (optional RS232C, RS485).
2. Data input/output can be completed with simple sequence commands.
When reading data from SCU, use PLC application command [READ], and when writing data to SCU, use application command
Execute with [WRT]. Post processing is run by shared memory between CPU UNIT and SCU, so complex programs
No need to create.
3. SCU Units have added RS-485 network functionality to the previously used N series SDU modules,
Expanded its usefulness.
4. The network can be constructed using RS232C communication and RS485 communication.
Can input/output data with RS232 devices:
Can be connected to IDX displays, instruments, barcode readers, printers, etc. for data input/output
Data can be input/output through the network with h RS485 device:
Connect to temperature controller, network frequency converter, and network servo through the network
5. Can be installed indefinitely in the PLC slot, transmitting 500 bytes at a time.
6. The available transmission codes can also be ASCII or HEX (Binary).
7. During communication, the terminal code can be freely set to PLC Ryder commands.
