electronic products, communication products, mechanical and electrical products,
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.
