Safety precautions
Control system design attentions
Dangerous!
Make sure design the safety circuit, to ensure that the control system can still work
safety when the external power supply cut off or PLC broken.
Make sure set emergency braking circuit, protection circuit, interlock circuit of forward-
reverse running in PLC external circuit and upper-lower limit switch to prevent from
machine damage.
In order to make the equipment safe operation, please design external protection circuit
for important output signal.
PLC CPU will close all the output when detecting the system error; the output will lose
control when the PLC circuit has problem. Please design suitable external control circuit
to ensure the device working normally.
If the PLC relay or transistor unit is broken, the output cannot be ON or OFF.
The PLC is designed for indoor environment, the lightning protection must be installed
in the power supply system to avoid PLC and other device damage.
Installation and wiring attentions
Dangerous!
Do not use the PLC in the following environment: dust, soot, corrosive gases,
flammable gas, high temperature, condensation, vibration, impact, lightning, fire.
Do not let the metal scrap and wire head drop into the ventilation hole of PLC, otherwise
it will cause fire or error operation.
Do not cover the ventilation hole of PLC, otherwise it will cause fire, error operation.
The I/O wiring must be fixed enough, otherwise the bad contactor will cause fault.
Attention!
It can use external power supply for extension module DC24V power.
Please use shield cable for high frequency I/O wiring to avoid interference.
Run and maintenance
Dangerous!
Please connect all the cable include PLC, extension module and BD board after shutting
down the power supply.
Please operate as the manual for online operation, forced output, RUN, STOP.
Attention!
Please discard the product as industrial waste.
Make sure cut off the power supply when installing or uninstalling the extension card.

Steps:
1. open the XDPpro software, find the left project bar, click PLC config/ED.
2. choose the correct module type.
3. set the module parameters such as current input range.
4. click write to PLC, then re-power on the PLC to make the setting effective.
Note: first-order low-pass filtering weighted this sampled value with last filter output value,
and got the effective filtering value. The filter coefficient is set by user, the range is 0-254,
0 means no filter.
External connection
Please pay attention to below items when wiring:
①please use shield cable to avoid interference, and single point connect to ground
for the shield layer.
②when XD-2AD2PT-A-ED connects external＋24V power supply, please choose the
power supply from PLC to avoid interference.
Current single-ended input
XD-2AD2PT-A-ED current input wiring:
PT100 temperature input
Programming example
Example: it needs to collect one channel pressure sensor signal (pressure sensor
performance parameter: pressure range 0Mp~10Mp, output signal range 4~20mA), and real-
time read one channel of PT100 temperature signal.
Analysis: as the pressure sensor testing range is 0Mp~10Mp, and related analog output is
4~20mA, the ED module AD transformation range is 0~4095. So 0Mp~10Mp is related to
digital range 0~4095. 10Mp/4096=0.0024414 is the pressure value related to digital value 1.
So the real-time pressure=ID register value * 0.0024414. For example, ID register value is
1024, so the pressure is 2.5Mp.
Note: please use floating number for calculation, otherwise the calculation
precision will be error!
Explanation:
SM0 is normally ON coil, it will be ON when PLC is running.
PLC will calculate the pressure value P related to digital value 1, then transform the
ID30000 value to floating number. So the real-time pressure=ID30000*P.
Note: In this example, please set ON channel 1 and 3 enable bit Y30000, Y30002.
