When state, obtained with the point on the one-to-one discrete magnitude input module 7 of contact 9 of external relay 2 true external
The contact 9 of relay 2 is closed input signal " 1 ", and is shown on host computer 3, it was demonstrated that 7 institute of discrete magnitude input module to be detected
There is output point bit function normal, when showing the closure input signal of contact 9 on host computer 3 is " 0 ", such as external relay 2
KA12 movement, at this time discrete magnitude input module 7 because KA12 normal opened contact 110 be closed, but its correspond to the 12nd point do not work, then be with
Corresponding the 12nd point failure of discrete magnitude input module 7 to be checked of the contact 9, recording mark, it is necessary to enter targeted in next step
Maintenance.
Wherein, it in step A), removes the discrete magnitude input module 7 being mounted in test module mounting groove or discrete magnitude is defeated
Out before one in module 8, it is closed external control power supply 10, is started by host computer 3 and is detected, guaranteeing all functions of modules just
Often, the case where same point of discrete magnitude input module 7 and discrete magnitude output module 8 breaks down is avoided the occurrence of, in order to avoid lead
Cause detection erroneous judgement.
In addition, by PLC bottom plate rack 1, CPU module 4, communication module 5 and power supply in the device of emulation detection PLC module
Any of module 6, which is removed, replaces with corresponding PLC bottom plate rack 1, CPU module 4, communication module 5 and electricity to be detected
Source module 6 is closed external control power supply 10, is started by host computer 3 and detected, if host computer 3 cannot show normal signal, replaced
The module changed is malfunctioning module.
The present invention, which emulates the device of detection PLC module and its detection method, realizes the input of PLC discrete magnitude, output module
Emulation detection, detection effect reach 100%, repair for next step and provide technical guarantee, reduce spare parts cost and depot repair
Expense reduces the high spare part expense of discrete magnitude module, prevent during the depot repair because spare part be in an emergency influence production platform when, and
Cause to lose benefit；And it is operated and is shown as a result, making good use of module using Shift Method using the present apparatus and host computer 1 and detection is gone to doubt
Like the modular approach of failure, fault point can show that convenient and efficient, simple and practical, effect is bright on operation screen at once
It is aobvious, and save a large amount of time.The present invention utilizes innovative thinking homogeney principle, has promotional value on same category of device,
Complete maintenance conditions equipment can be made, product, which is externally promoted, certain economic value, also breaches producer's limitation, is able to achieve
We independently emulate all kinds of PLC modules of detection.
