S7 access to the ore pool

1. If you want to set up such an excuse, it is relatively easy. You can link the two devices directly through the setting center, and then you can use them normally.

2. Android mobile phone reset access point method: Set - (connect) - more network - Mobile Network - access point name - menu key - reset to default settings.

3. Samsung S7 mobile phone reset access point method: Set - (connect) - more network - Mobile Network - access point name - menu key - reset to default settings.

4. Are you sure the output is pulse signal, not current signal

if the output of electromagnetic flowmeter is 4 ~ 20mA signal, it can be directly accepted and stored by PLC. Siemens PLC has a special 4 ~ 20mA input point, so it only needs to control the PLC program well

if it is pulse, it needs to be connected to a special high-speed input point< Since there is no corresponding algorithm to calculate the frequency in PLC, it is necessary to program the following three parts in step 7 micro / win to measure the instantaneous flow of the flowmeter with pulse output signal:
(1) define the high-speed counter to count the output pulse of the flowmeter
(2) timing interrupt is used to collect high-speed pulse input in cycle time
(3) calculate the high-speed input pulse frequency and use the flow conversion formula: instantaneous flow (ml / s) = pulse frequency (pulse / s) ÷ The instantaneous flow was calculated by pulse / ml
for specific programming, I have posted in Siemens community. You can just go and have a look, OK< br /> http://bbs.gongkong.com/proct/SiemensPLC.htm

5.

The wiring diagram of

PLC and proximity switch is as follows:

when the input sensor is proximity switch, as long as the output driving force of proximity switch is enough, the PLC input end of drain type input can be directly connected with the output of NPN collector open circuit proximity switch

6. 200 seems to have no network port expansion mole. You can buy a communication mole with network port to serial port

7. The mobile phone / tablet can't connect to the apple computer. We suggest that you:
1. First, install the KIEs software (Mac version) in the computer. When installing the KIEs software, the mobile phone / tablet can't connect to the computer
2. Turn off USB debugging: settings - Developer options - USB debugging - turn off
3. Connect the computer again. If it still can't be connected, replace other data cable or USB interface and try again
4. If it is invalid, please back up the data in the mobile phone / tablet, and then restore the factory settings (settings reset / privacy / personal restore factory settings)
5. If the above operations are invalid, it may be related to the compatible program of the computer system. If possible, you can also replace other computers to try to connect
if the problem still exists according to the above method, please take the purchase invoice, warranty card and the machine to Samsung service center, and the engineer will check the machine and deal with it.

8. Hello
the two terminals in the same row on the left and right are short circuited, and then connected to the two ends of the signal respectively, a total of 8 channels
if you have any questions, please ask.

9. Mobile wap access point can browse WAP web pages, such as mobile dreamnet; Net access point can only browse HTTP pages.
