In 1993, General Measure was established in Shenzhen, China. For decades, GM has been focusing on the industrial weighing process, adhering to technology promoting development. The company headquarters is in Shenzhen International Innovation Valley Industrial Park. In 2017, a new weighing instrument and equipment production base was set up in Zhuzhou, a manufacturing hub of China. Three domestic sales offices are in Beijing, Wuxi, and Shenzhen. There are 14 strategic partners in Canada, Brazil, Turkey, India, Thailand, Australia, South Africa, etc. Products are sold in 42 countries and regions around the world.
Hello, welcome to the General Measure's Channel. Today's topic is 'weighing indicator GMT-P1(TCP) communication port troubleshooting'. After watching this video, you will know how to find out the Modbus TCP connection problem.
The main causes for TCP connection are two problems; one is hardware problem:
1. Network cable connection problem.
2. The chips or circuits of the indicator are broken.
3. The external devices are broken.
Another is the communication parameter setting problem:
1. The parameter setting error.
2. The IP Address is duplicate.
Troubleshooting demonstration:
First, by connecting GMT-P1 with the network cable and the power supply, we can clearly know the network connection by checking the two indicator lights next to the network port slot.
1. Green light is on, yellow light is flashing, which means the network is connected well.
2. Both green light and yellow light are flashing, which means connection failed. We need to reconnect the cable or power off the indicator and restart it.
3. Neither green light nor yellow light is on, which means connection failed as well. In this case, the chip or circuit of network port may be broken. It is recommended to return to depot.
Then set the IP address and port number in the communication parameters of the GMT-P1; we need to set it as a unique IP that cannot be used in any other indicators. Otherwise, the connection will fail.
Open Modbus-Poll software, click Connection on the menu bar, and set IP and port on the pop-up window. The IP and port should be consistent with those specified on the indicator. Otherwise, modbus communication will fail.
If the communication is successful, it can be seen that the No connection at the top of the address table disappears, and then the data of Tx is constantly changing.
Suppose Modbus-Poll still displays a timeout message after following the above steps. In that case, the network port of the external network device may be broken, or the external network device (switch) is broken. Thus, you can change the external network port or change the external network device.
If the above troubleshooting methods cannot help you solve the problem, we can say it is the indicator hardware's problem. You can contact our technical support for help or return to depot.
General Measure’s ChexGo Series checkweigher CW-15K has been applied in the daily necessities production factory for double-checking the weight after the packing process.
In some countries, following the regulation, the daily necessities manufacture should build checkweigher at the end of the production line to ensure the product integrity. The underweight and overweight packs can be rejected by different types of rejectors, such as push-type, air blow, swing arms or roller conveyor, etc. Suppose there are several products packed overweight or underweight continually. In that case, we can set a maximum number of rejected product alarms, reminding us to check the production line to cut loss and avoid risk from production line damage.
The module design touch screen makes it easy to set up, check, and export the weights data. The stainless steel and hygienic convey belt are perfect for daily goods or food products. With adjustable feet, it can be integrated with different designs of existing production lines. The design of ChexGo serial follows the user-friendly principle.
Currently, GM’s checkweighers are well-running in different applications like food manufacture, pharmaceutic factory, daily necessities manufacture, cosmetics manufacture, logistic industrial and so on.
