OEMAX-NX700-UM009A-KO-P-Serial communication unit

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.
