SD812F 3BDH000014R1 Custom Decoding Modules

SD812F 3BDH000014R1 in the simulation debugging or practical applications, if the system can not be in accordance with the requirements of a circuit action, first of all, you should check whether the PLC input switch contact point is reliable (generally through the input LED indicator or direct measurement of the input), if the input signal fails to pass to the PLC, you should go to check the input corresponding to the external circuit; if the input signal has been captured, and then look at the PLC whether the corresponding output indicator, if not, is the problem of the internal procedure or the output LED indicator problem; if the output signal is already sure to send out, then you should go to check the external output circuit.

SD812F 3BDH000014R1 The entire PLC internal programme, external output points and wiring increase little, and the performance price is relatively high. If the input signal has been captured, then look at the PLC to see if there is a corresponding output indication, if not, it is the problem of the internal procedure or the output LED indicator; if the output signal has been convinced to send out, then you should go to check the external output circuit (from the PLC output backward to check).

SD812F 3BDH000014R1 Network Listening Method (i.e. OTP method or hacking method) At present, the normal working process of ATM machine almost always requires the ATMC side (the usual ATM machine) and the ATMP side (the bank’s data centre) to communicate normally through the network line.The ATMC side needs to send the customer’s line code, card number, the user’s password and other information to the ATMP side through the special network after the information is encrypted. The ATMC side needs to send the customer’s line code, card number, user’s password and other information, which are usually encrypted, to the ATMP side through a dedicated network, and the user can only carry out normal enquiry or withdrawal operations after authentication by the ATMP side. This method is to intercept the card number when the ATMC terminal uploads the card number and other information to the ATMP terminal.
