4 Application Example
4.1 Basic Application
Example: MC200-4AM module address is 1 (for the coding of extension
modules, please refer to the
MC200 Series PLC User Manual
). Use its input
channels 1 and 2 for voltage signal input (-10V~10V), set the average
sampling times to 4, and use data registers D3 and D4 to receive the average
value; set output channel 1 to mode 0 and for 10V voltage signal output, and
set output channel 2 to mode 1 and for 20mA current signal output.
4.2 Changing Characteristics
Example: The MC200-4AM module address is 3 (for the coding of extension
modules, please refer to the
MC200 Series PLC User Manual
). Set
characteristics A in Figure 3-3 for input channel 1, and characteristics B in
Figure 3-3 for input channel 2; set their average sampling times to 4, and use
data registers D3 and D4 to receive the average value. Set characteristics A
in Figure 3-6 and 10V voltage signal output for output channel 1, and set
characteristics B in Figure 3-6 and 20mA current signal output for output
channel 2.
5 Operation Inspection
5.1 Routine Inspection
1. Check that the wiring meets requirements (refer to
1.3 Wiring
).
2. Check that the extension cable of MC200-4AM is properly inserted in the
extension port.
3. Check that the 5V and 24V power supplies are not overloaded.
Note: the digital circuit of MC200-4AM is powered by the basic module
through the extension cable.
4. Check the application, make sure that the correct operation method and
parameter setting range are selected.
5. Set the MC200 basic module to RUN state.
5.2 Fault Inspection
In case of MC200-4DA malfunction, please check:
●
the status of the POWER indicator
ON: the extension cable properly connected;
OFF: check the extension cable connection and the basic module.
●
the wiring.
●
the status of the 24V indicator
ON: 24Vdc power supply normal;
OFF: Possibly the 24Vdc power supply failed; if not, MC200-4AM is faulty.
●
the status of the RUN indicator
Flash quickly: MC200-4AM in normal operation;
Flash slowly or OFF: check the data in BFM#34.
Notice
1. The warranty range is confined to the PLC only.
2.
Warranty period is 18 months
, within which period Megmeet Network
Power conducts free maintenance and repairing to the PLC that has any fault
or damage under the normal operation conditions.
3.
The start time of warranty period is the delivery date of the product
, of
which the product SN is the sole basis of judgment. PLC without a product
SN shall be regarded as out of warranty.
4. Even within 18 months, maintenance will also be charged in the following
situations:
Damages incurred to the PLC due to mis-operations, which are not in
compliance with the User Manual.
Damages incurred to the PLC due to fire, flood, abnormal voltage, etc.
Damages incurred to the PLC due to the improper use of PLC functions.
5. The service fee will be charged according to the actual costs. If there is any
contract, the contract prevails.
