S7 miner IP
As shown in the figure, 
the reset button is located on the right side of the network port, next to the red and green lights
after the machine is powered on, wait 2 minutes for the miner to start up, press and hold the reset button for 10 seconds (gently poke in with a pen or toothpick, and the hand can't reach the position), release the power, and then power on after 1 minute
the IP address of S7 mining machine is reset
PLC NC him and even the keyboard have their own fixed address
because of different system models and different addresses, 840D and 802D keyboard addresses are different
if you only ask how to set the PLC address, if it is in the system, you can set it when selecting PLC. In the first framework, if you are outside the system, it is the PLC itself There is a small comb band switch. What's the address in your system? Just set the system switch outside the system with your finger. Finally, the combination of the switch number can meet your address number
The default factory IP is generally 0.0.0.0
the IP address is generally set in the system ring programming
in the hardware configuration, the Ethernet mole is set
if the IP address of the touch screen is 192.168.2.1
PLC, it is necessary to set 192.168.2.2
notebook network port to 192.168.2.100
if it doesn't work, check the setting and whether the network port supports two-way communication
extended data:
all SIMATIC s7-1200 hardware has built-in buckle, which can be easily installed on the standard 35 mm DIN rail. These built-in buckles can also be clamped into the expanded position, and can provide mounting holes when the panel needs to be installed
SIMATIC s7-1200 hardware can be installed in horizontal or vertical position, providing other installation options. These integrated features provide users with maximum flexibility in the installation process, and enable SIMATIC s7-1200 to provide practical solutions for various applications
1. Double click to open STEP7 5.5 programming software
{rrrrrrr}
to modify the IP address of PLC through Ethernet. This method is suitable for any version of step 7 software and S7-300 / S7-400 PLC
that is, after setting the IP address of the offline CPU, in the download window, check "show all accessible devices", select the corresponding CPU to download, and change the IP address to the set IP address
2: for a new CPU that has not set an IP address, you can set the IP address directly
open the basic software - online access - open the connection network card - double click "update accessible device" - find the CPU - "online and diagnosis" - assign the IP address to the CPU - the first three octets of the IP address are consistent with the computer, and the fourth octet should be separated from the IP area of the computer; The subnet mask should be consistent with the computer
3: another is "reset IP address"
open basic software online access find the CPU online and diagnose reset to factory settings select reset IP address. In this way, the IP address of the CPU including the program is cleared, that is, the factory status is restored
01 is PG, 02 is op, 03 is S7 unilateral (server mode), 10 (HEX) and above is S7 bilateral communication. The second byte is the access point, which may be the CPU slot number, CP slot number, etc.
1. Double click to open STEP7 5.5 programming software
PLC through the connection programming computer, open the botu software, click to access the device, interface type select pN / ie, pg / PC select your network card, motor search will come out
1. Open the setp7 smart software, find the system block on the left, and double-click
the PLC needs to set 192.168.2.2
the laptop network port can be set to 192.168.2.100
if it is not available, check the setting problem and whether the network port supports two-way communication.
