Multi function switch type A: S7-1200/S7-300PN plus smart touch screen adapter

A product function:

1, can connect S7-1200PLC and SIEMENS SMART wonderful series touch screen.

2, you can connect S7-300 PN and SIEMENS SMART wonderful series touch screen.

3, you can connect S7-300 CP343 Ethernet module and SIEMENS SMART wonderful series touch screen.

4, you can connect S7-400 PN or CP443 Ethernet module and SIEMENS SMART wonderful series touch screen.

5, S7-1200PLC and SIEMENS WinCC can be directly connected (using S7-300 TCP/IP protocol) without OPC transfer.

6, S7-200 SMART and SIEMENS WinCC can be directly connected (S7-300 TCP/IP protocol) without OPC transfer.

the number of A products connected to PLC and HMI (Smart touch screen or WinCC host computer).

1, each multifunctional switch can connect 3 PLC (S7-300 PN/CP343-1/ETH-MPI/S7-1200/S7-200 Smart) at the same time.

2, each PLC can communicate with 3 HMI (Smart touch screen or WinCC host computer) through multi-function switch.

the expansion and interconnection of multi-function switch ports

1, when the port of the multifunction switch is not used enough, it can be enough to buy a TP-LINK 8 switch and connect the two switches at any port with the network line, and the port expansion can be realized.

2. When more than two multifunction switches are used, a network line can be used to connect any port of the two switches to realize the interconnectivity of the switch ports, but do not form a ring connection.

Working principle of A product

1, there are 3 continuous IP addresses inside the multifunction switch, and each IP address is bound to one of the IP addresses of a PLC, that is, each internal IP corresponds to a PLC (IP address).

2, for example, Smart access a IP inside the multifunction switch, which is actually accessing the PLC (IP address) bound to it.

3, the specific process of Smart communication is:

The A, PBX's internal processor receives access to the Smart's access data to the internal IP address, and then converts it to the format required by the PLC, and sends the IP address to the binding PLC.

After processing B and PLC, the returned data is sent to the internal IP address of the multifunction switch. The processor converts it into the format required by Smart and sends it back to Smart.

4, the process of WinCC is completely similar to that of Smart, but the format of data transformation is different.

the setting of multifunction switch:

1, the backdoor IP address of a multifunction switch is xxx.xxx.xxx.222: (for example, 192.168.1.222, 192.168.0.222); a computer and a multifunction switch are connected through a network line

2, typing the backdoor IP address in the IE browser of the computer can enter the main menu of the multi-function switch; of course, it can also enter directly with the actual initial IP address.
