Detailed Description
Description:
Main technical parameters:
isolation voltage: 1000VDC
have transient voltage suppression, RS485 port can withstand the power of up to 500W transient overvoltage and lightning impulse, RS232 port and a power supply circuit are equipped with surge protection protection circuit, the product can be any live insertion
baud rate: 0 ~ 115.2kbps adaptive
maximum communication distance: 2 km (baud rate is 9600bps), 1 kilometers (baud rate is 115.2Kbps)
with power indicator and data receiving, indicating lamp
working temperature: -40 ~ 85
dimensions: 103 x 50 x 26, total cable length of 4.5 meters
Product structure:
Product use:
1, PLC and computer connection for PPI or free port communication, programming:
Only the 3CB30 RS485 cable plug S7-200PLC programming, RS232 plug is inserted into a computer RS232 port, and in the programming software is chosen to correspond to the COM 10bit, 11bit slogan, select switch to 11bit position and.
The 3CB30 cable baud rate is 0 ~ 115.2kbps adapted to automatically, without setting.
2, PLC and computer long distance communication:
When the long distance communication 3CB30 extra power, and in the RS485 plug, between 8 and 3 with 120 ohm termination resistor to eliminate signal reflection, as shown below:
3, PLC through the telephone line with the computer remote communication:
3CB30 RS232 end of the MODEM when connected with a DCE/DTE crossover adapter, and according to the 10 or 11 bits MODEM cable on the switch to a corresponding position.
10 MODEM means: 1 start bit, 8 bits of data, no parity bit, 1 stop bit (or 7 data bits, 1 parity bit), which is in the market on the more common MODEM.
11 MODEM means: 1 start bit, 8 data bits, 1 parity bit (my school), 1 stop bit MODEM.
