TRICONEX-3201 Siemens S7-200PLC do server configuration routines

Ethernet module configuration I was originally to assist a system integrator (hereinafter referred to as the “host computer”) to do Ethernet communication. Our TRICONEX-3201 two cabinets are used as sub-stations (servers) in the system, and the IP address and number of computers to be accessed are not requested by the customer in advance, and the system integrator is also obtained at that time. After arriving at the site, I first re-configure one CPU224 by “Ethernet Wizard” according to the customer’s requirements. The specific operations are as follows:

First of all, open your own program through STEP 7 MicroWIN software, as shown in Figure 1.

Fig RICONEX-3201Open the “Ethernet Wizard” in the menu “Tools” and click “Next” in the pop-up dialog box to appear the module specified in Figure 2

In the address dialog box, click “Read Module” to search for the module with CP243-1 installed, and double-click the searched module to specify the location of the module in the CPU. Click “Next”, the IP address dialog box of the module in Figure 3 will pop up, where you can set the required IP

TRICONEX-3201 Address, subnet mask, gateway. Click “Next” to pop up as shown in Figure 4. The option of “module command word” can be used by default.

“Peer connection” here can specify the number of computers to be accessed, up to 8 supported, generally set it a maximum of “8” free after the customer and find you “trouble”. When the setting is complete, “Next” pops up the Configuration connection dialog box, as shown in Figure 5 for each connection channel

TRICONEX-3201 Configure the communication mode. The PLC here serves as a server, that is, for remote computer (client) access, and the PLC does not need to write any communication program. So all channels are configured as servers and “accept all connection requests,” meaning there is no need to specify the IP address of the remote client. Otherwise, you need to specify the IP address of the remote computer to access. Pay special attention to the “Local Properties TSAP 10.01” for each connection channel. It is different, and some upper computer software needs this port number to communicate. The rest of the steps are
