computer software development. In the case of the same function and the same I/O point data, the integral is cheaper than the module. But the modular type has the advantages of flexible function expansion, convenient maintenance (replace the module), easy to judge the fault, etc., to choose the PLC structure form according to the actual need. Assigning input/output points Generally there is a one-to-one correspondence between input points and input signals, and output points and output controls. After allocation, according to the channel and contact number
configured by the system, assign each input signal and output signal, that is, number. In some cases, there are two signals with one input point, so the input point should be connected in a logical relationship before the input point (such as two contacts in series or parallel), and then connected to the input point. (1) Determine the I/O channel range of different models of PLC, the range of the input/output channel is not the same, should be according to the selected PLC model, consult the corresponding programming manual, never “Zhang Li Di Di”. You must refer to the relevant operation manual. (2) Internal auxiliary relays do not output externally and cannot be directly connected to external devices, but are used for data storage or data processing when controlling other relays, timers/counters.
