Hello. 1
In this video we are going to learn PT temperature module DVP04PTSD. 2
On the left side you can see three wire and the two wire connection for PT100. 3
We need to use three wire cabling. 4
So this is because of resistor. 5
You can put two cable to L + and L - and the third cable needs to connect to I - 6
for PT1000. 7
You have to wire cabling. 8
So for this to wire needs to connect to L + and L -. 9
But the important point for the PT1000 I - must be bridged with the L -. 10
You need to put a bridge between L-and I- thats all. 11
And also you need to give 24V to your special modules .For the control registers 12
for control register 1. 13
We need to adapt our mode settings and the for the bits. 14
If you put bit zero bit two bit three. 15
If you put this bits 0 0 0 0 PT100 is selected for the special modules for PT1000. 16
You need to put this bits 0 0 1 0. 17
Also you can see Channel 1 starting from b0 and Bit 3, channel2 bit 4 and 7, Channel3 bit 8 18
and bit eleven. 19
Channel 4 bit 12 and 15. 20
Imagine in example Channel 1 and 2 is pt100 is connected to channel 1 and Channel 2 and the 21
PT1000 is connected in your application Channel 3 and Channel 4. 22
So how you need to , how you can adopt your mode set things for the special module so we need 23
to inform our special modules. 24
Okay. 25
We will connect these sensors to your input than you need to read them and you need to give the 26
data from the sensors to us. 27
So we need to say these things to our special modules or how our special modules knows which sensor 28
is connected to it. 29
So in here for Channel 1 what we put Pt100 ,PT100 was completely 0, four 0 here, for Channel 2 PT100 and 30
four 0 here. 31
Channel 3 and 4 PT1000 was 0 0 1 0 / 0 0 1 0/ 32
So in here this is 0. 33
This is 0. 34
This is 2. 35
This is a binary and the binary 0 0 1 0 equals decimal 2. 36
And also this is 2. 37
So you need to put them all together hexadecimal two thousand two hundred two, 38
That you need to write. 39
Control register 1 with the TO command. 40
You need to put this value to control register 1 and then you need to put your connections correctly. 41
Channel 1 and 2 PT100, channel three and four PT1000 and then 42
You will read completely the temperature datas from the sensors. 43
So for this video I'm finished here. 44
See you in the next video.
