    2.8 How to select 7520 / 7520R The 7520R is exactly the same as 7520 except for the isolation site. The isolation site of the 7520 is located in the RS-232 interface circuit, but the isolation site of the 7520R is located in the RS-485 interface circuit.
  • Page 21 Note: the power ground of 7000 common RS-485 is ground. This is the same for Adam 4000, Nudam 6000 and DATAFORTH 9B series modules. In most applications, the 7520 are used to convert the RS-232 signal to RS-485 network. Normally the 7520 does not use the same DC power ground as the Host PC/PLC, and the isolation site is in the RS-232 section.
  • Page 22 Host PC/PLC will be isolated from RS-485 network in all conditions. The power adapter PWR-24 is designed for single 7000 series modules only. The 24V DC output of the PWR-24 is isolated from its AC input. If the 7520 or 7520R is connected to the PWR-24, this PWR-24 cannot connect to the other module.
  • Page 23 The 7520R is designed for PLC networking. During normal conditions, the PLC system will have a stable DC-24V power source. The user may use this power source to 7520R(configuration A). When using 7520, the user must use another power source, PWR-24 (configuration B).

  • Page 68 For example, the 7510, 7510 are used to isolate local modules from RS-485 network. If there is high energy transient on RS-485 network, all the local modules will be safe. Isolation Configuration (Strongly Recommended): If the RS-485 network is not over 100 meters, the terminated resistors are not needed.
  • Page 69 It is recommended to use the “trial and error” rule. The trial and error rules are given as follows: If the length of RS-485 is about 1.2 Km, try 330Ω first Run TEST.EXE of DCON_DOS Select function_5, run continuously for at least 8 hours to make sure communication is OK.

    PLC Networking Applications These PLCs can be used at different baud rates & different configurations. For example, PLC-1=1 start + 7 data + 1 stop=9-bit/byte, baud rate=1200 PLC-n=1 start + 8 data + 1 parity + 1 stop=11-bit/byte, baud rate=9600 PLC-m=1 start + 8 data + 1 parity + 2 stop=12-bit/byte, baud rate=115200 OMRON CQM1 = 1 start + 7 data + 1 even parity + 2 stop =11-bit/byte...

    7000 series. We call it a “slave-PC address”. The module address of the 7000 series is limited to 256, but the slave-PC address is unlimited. The user can connect thousands of PCs in one RS-485 network by using a repeater, the 7510.

    RS-232 Devices Network (For this application, we recommend to use i-7520U to replace the i-7520) Some RS-232 devices can be connected to the 7000 RS-485 network very easily, just like the PC or PLC introduced in Sec 6.2 and Sec. 6.3.
