￿RS-232 device RS-232

Some RS-232 devices can be connected to the 7000 RS-485 network very easily, just like the PC or PLC introduced in Sec 2.7 and Sec. 2.8. These RS-232 devices must adhere to 3 rules given as follows:

Rule 1: cannot send out the RS-232 signal in normal, operating state.

Rule 2: every device has a unique device address

Rule 3: will not send out a RS-232 signal if the destination address does not match with the device address

The software for RS-232 device networking and PLC networking is very similar. The only difference is the command format. The command format of PLC is always different for different manufacturers. Refer to “NAP000S User Manual” for software details.
