5 Define the communication parameters. Set the priority to low. Check the value of the local address LADDR for the configuration of the FB7.

6 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.

13 REF. PLC node and Controller s 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 < S7-300/400 CPU Set up > 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.

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

15 (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. Assign or to the Local Connection depending on the switch value specified on the side of the PC Adapter. (4) TOP Menu Assign or to the Baud Rate depending on the switch value specified on the PC Adapter. Other values, including Data Bit, are automatically configured.

As the real number area increases by 4, enter 0, 4, 8, 32 bit Word Swap is selected only for the 32 bit positive number, not for the real number. The decimal place of an address in real number shall be constant in all screens. Once the number tag is registered, the decimal place shall be the same in every screen. It is not applicable if the address is different. *1 : Data Register DB Word Address: ~ 65534(even number) Data Block (DB) No.: 001 ~ 256 * Add two digits to the end in Bit. DB Bit Address: 00 ~ 07 Generate the tag in BCD for a timer and counter. < Note >

19 If the word array is allocated in the DB34, 0 and 1 are allocated in the first area, 2 and 3 are in the second area, and 4 and 5 are in the third area. If you use a number tag or a key tag to read the second area in word value, set the device address to 2 in the TOP (DB ). If you need to access bits, for example, lamp tag or touch tag, set the address to 2 for the high byte, while set the address to 3 for the low byte. To access to 00 bit high byte in the second area: DB To access to 00 bit low byte in the second area: DB The last two digits 00 indicate the location of bit, which is definable from 00 to 07. Turning the DB ON reads 256 in number tag (word). Select 32 Bit and 32 Bit Word Swap to indicate the 32 bit positive number.
