Select the RK-512 protocol for the S7, while the 3964R protocol for the S5. Also add the

Receive Function Block FB7.

The CP340 is not supported by the latest version of PC software.

Define the communication parameters.

Set the priority to low.

Check the value of the local address LADDR for the configuration of the FB7.

Open OB1, and drag and retrieve the FB7 P_RCV_RK CP341 from the CP 341 folder in the

program elements.

Enter the DB number (DB7) to be used by the FB7 to receive the communication on the

top. Then the corresponding DB is automatically created. Turn the EN_R ON to enable

the communication. R is reset input, and LADDR is the local address value checked in

the previous step.Enter one of DB Nos. to be used. The read/write communication is

available within the assigned DB area only.

1.1.3.3 TOP Setup

(1) TOP Designer Setup

Select the Siemens MPI Direct in the Target PLC type.

Configure the MPI Address of TOP on Station No.,the MPI Address of S7 on PLC Node

(2) TOP Serial Setup

Recommended settings are as follows.

- Serial Baud Rate : 187500 bps

- Serial Data Bit : 8bit(Auto set)

- Serial Stop Bit: 1bit(Auto set)

- Serial Parity Bit : EVEN(Auto set)

- Serial Signal Level : RS-485

- Controllers Station No. at Comm. Diagnosis(0~31) : Not effect.

PLC node and Tops station No must be set differently each other.

We recommend Highest Node 15.

1:n, n:1 and n:m connection is not supported, but 1:1 connection is only

supported.

MPI Direct is supported only XTOP model.

1.1.3.7 TOP Setup

(1) TOP Designer Setup

Select S7-300/400 MPI(LOADER) of Siemens Series in PLC type.

(2) TOP Serial Setup

Recommended settings are as follows.

- Serial Baud Rate : 19200 bps

- Serial Data Bit : 8bit

- Serial Stop Bit: 1bit

- Serial Parity Bit : ODD

- Serial Signal Level : RS-232

- Controllers Station No. at Comm. Diagnosis(0~31) : 1

PLC node and Controllers station No must be set differently each other.

Highest node should not exceed PLC node. For example, If PLC node is set 16

by user, highest node should be set 31 or above.

1.1.4 < S7-300/400 CPU Set up >

1.1.5 Configuration of S7-300/400 CPU >

(1) Hardware Configuration

Assign 187.5Kbps to the Transmission rate in the Network Setting tab of the MPI interface

as shown in the figure below. Change the highest address to 15 for a fast connection in the

communication network.

REF.

(2) Options > Set PG/PC Interface > PC Adapter > MPI

Assign 187.5 Kbps to the Transmission Rate as shown in the figure below. As the Highest

Address is for the PC, the value is different from the MPI address.

Select the Highest Node Address in the TOP Designer in case a PC Adapter is used. (see

Project Information in the Designer)

(3) Options > Set PG/PC Interface > PC Adapter > Local Connection

The Local Connection is the speed at which the PC communicates with the TOP in case a

PC Adapter is used.
