TwinCAT ADS - Write value to PLC
Hi all,
I'm using the TwinCAT ads driver with the 0.8.0 realease of PLC4X. I can read all the values from the PLC without issue, but writing doesn't seem to work.
I don't know what Im doing wrong.
Here is the writing code:
PlcDriverManager driver = new PlcDriverManager();
try {
PlcConnection plcConnection = driver.getConnection(
"ads:tcp://10.10.11.77?sourceAmsNetId=172.29.64.1.1.1&sourceAmsPort=32&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");
if (!plcConnection.getMetadata().canWrite()) {
return;
}
PlcWriteRequest.Builder builder = plcConnection.writeRequestBuilder();
builder.addItem("lightToggle", "MAIN.E_Lum_1:BOOL", true);
PlcWriteRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
if (exception == null)
System.out.println("WRITING DONE....");
else
exception.printStackTrace();
});
If I change the "MAIN.E_Lum_1:BOOL" to a value that doesn't exists I get a error saying me the name is invalid which is fine and tells me its really communicating with the PLC.
Now, when using the good name, I don't get an exception and I see thee "WRITING DONE..." in the console. However, the value is unchanged in the Beckhoff PLC.
Is there anything I don't understand ??
Thank you very much !!!
Here's the Beckhoff PLC setup:

Chris, here is what I found…
On the PLC Program, the value I was using was declared like this:
E_Lum_1 AT %I*:BOOL; --> NOTICE THE “AT %I*”
Now, I tried:
E_Lum_1:BOOL;
And all the sudden, everything works just fine. Here’s a JPEG of the UI (kafka consumer). Data is provided by a back-end app and PLC4X (of course) and producing the data into Kafka.
A big thank you for everything !

Hi Chris, ty you very much for your time and the video you provided.
I did the same thing as you and I’m seeing the exact same behavior.
When I stop the PLC program, I can see the value changing.
Again, ty you very much for your time. It is greatly appreciated.

And I just did another check ...
I simply commented out the line in my program, wehre I explicitly set the value oft he variable and I could change it from the driver even in run mode. I did also set a breakpoint in the initialization code I had and I had the PLC stop on every cycle.
So @Patrick Boisclair please double check you are not simply overwriting the values again like I was.

Ok ... that was a quick one ...
I think I solved the mystery :-) ...
The driver is actually doing what it should and seems to be doing it correctly.
I tried my test again, but having stopped the PLC programm. I did that cause I wanted to prevent the value being overwritten by any form of PLC program.
And as soon as I stopped the program execution, I could see the watch expressions I had setup change their value as expected.
In my case I setup a predefined set of variables to pre-defined values in order to run some manually executed tests against the device.
I think this initialization is run for every CPU cycle and hereby overwriting the changes the driver is sending.
Here a little video: https://drive.google.com/file/d/12e0Q4ewf8rIdPFcNYscH7xq5j_6RxAGY/view?usp=sharing
Hope this helps,

Hi all,
so I just setup the example and my Beckhoff PLC.
I can confirm that the value doesn’t change in the PLC. I used wireshark to inspect the communication between the driver and the PLC and the response to my write request is:
Frame 41: 96 bytes on wire (768 bits), 96 bytes captured (768 bits) on interface \Device\NPF_{7F615F1B-E091-421F-850E-2BC9EEC3A622}, id 0 Ethernet II, Src: Beckhoff_13:6a:a0 (00:01:05:13:6a:a0), Dst: GopodGro_02:d2:c7 (48:65:ee:12:d2:c7) Internet Protocol Version 4, Src: 192.168.23.20, Dst: 192.168.23.200 Transmission Control Protocol, Src Port: 48898, Dst Port: 50301, Seq: 51, Ack: 121, Len: 42 AMS

Subject: Re: TwinCAT ADS - Write value to PLC
I have one report from openHAB community that it is possible to write BOOL value just once, second and every next write does not pass. It does not even show up any traffic in Wireshark. I haven't confirmed cause yet.
I have not completed setting wiring and program for tests with CX (TC2) I got. I already found there is a trouble with reading of symbol table
(SYM_UPLOADINFO2) due to new IEC decoder. It seems that it attempts to read more than is available in underlying response from PLC.

Subject: AW: TwinCAT ADS - Write value to PLC
And I just did another check ...
I simply commented out the line in my program, wehre I explicitly set the value oft he variable and I could change it from the driver even in run mode. I did also set a breakpoint in the initialization code I had and I had the PLC stop on every cycle.
So @Patrick Boisclair please double check you are not simply overwriting the values again like I was.

The driver is actually doing what it should and seems to be doing it correctly.
I tried my test again, but having stopped the PLC programm. I did that cause I wanted to prevent the value being overwritten by any form of PLC program.
And as soon as I stopped the program execution, I could see the watch expressions I had setup change their value as expected.
In my case I setup a predefined set of variables to pre-defined values in order to run some manually executed tests against the device.
I think this initialization is run for every CPU cycle and hereby overwriting the changes the driver is sending.

Hi all,
so I just setup the example and my Beckhoff PLC.
I can confirm that the value doesn’t change in the PLC. I used wireshark to inspect the communication between the driver and the PLC and the response to my write request is:

I have one report from openHAB community that it is possible to write BOOL value just once, second and every next write does not pass. It does not even show up any traffic in Wireshark. I haven't confirmed cause yet.
I have not completed setting wiring and program for tests with CX (TC2) I got. I already found there is a trouble with reading of symbol table
(SYM_UPLOADINFO2) due to new IEC decoder. It seems that it attempts to read more than is available in underlying response from PLC.

AW: TwinCAT ADS - Write value to PLC
Posted by Christofer Dutz <ch...@c-ware.de>.
Hi all,
so I just setup the example and my Beckhoff PLC.
I can confirm that the value doesn’t change in the PLC. I used wireshark to inspect the communication between the driver and the PLC and the response to my write request is:
Frame 41: 96 bytes on wire (768 bits), 96 bytes captured (768 bits) on interface \Device\NPF_{7F615F1B-E091-421F-850E-2BC9EEC3A622}, id 0
Ethernet II, Src: Beckhoff_13:6a:a0 (00:01:05:13:6a:a0), Dst: GopodGro_02:d2:c7 (48:65:ee:12:d2:c7)

ADS Write Response

So from a protocol point of view it actually accepted the request and at least said that it processed it correctly.
I’ll check if my demo program might be setup wrong.

Subject: Re: TwinCAT ADS - Write value to PLC
I have one report from openHAB community that it is possible to write BOOL value just once, second and every next write does not pass. It does not even show up any traffic in Wireshark. I haven't confirmed cause yet.
I have not completed setting wiring and program for tests with CX (TC2) I got. I already found there is a trouble with reading of symbol table
(SYM_UPLOADINFO2) due to new IEC decoder. It seems that it attempts to read more than is available in underlying response from PLC.

I have one report from openHAB community that it is possible to write
BOOL value just once, second and every next write does not pass. It does
not even show up any traffic in Wireshark. I haven't confirmed cause yet.

RE: TwinCAT ADS - Write value to PLC
Posted by Patrick Boisclair <pb...@noovelia.com>.
Hi Chris,
I double checked and the value I’m trying to write is most definitely not being overridden.
I have tried with TwinCAT (within Visual Studio) and changed the value and it worked while the PLC program was running.
If you need more info or input, just let me know.
Ty very much

Hi Patrick,
I thought I had tested writing of values via ADS … will re-test.
But when writing you have to be sure the PLC doesn’t overwrite this value internally.
I remember when I tried „overriding“ outputs of PLCs with a written value. In the end it turned out that the value was overwritten, but the PLC program just set it to it’s original value as part of the program execution.

Betreff: TwinCAT ADS - Write value to PLC
Hi all,
I’m using the TwinCAT ads driver with the 0.8.0 realease of PLC4X. I can read all the values from the PLC without issue, but writing doesn’t seem to work.
I don’t know what Im doing wrong.
Here is the writing code:
PlcDriverManager driver = new PlcDriverManager();
try {
PlcConnection plcConnection = driver.getConnection(
"ads:tcp://10.10.11.77?sourceAmsNetId=172.29.64.1.1.1&sourceAmsPort=32&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");
if (!plcConnection.getMetadata().canWrite()) {
return;
}
PlcWriteRequest.Builder builder = plcConnection.writeRequestBuilder();
builder.addItem("lightToggle", "MAIN.E_Lum_1:BOOL", true);
PlcWriteRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
if (exception == null)
System.out.println("WRITING DONE....");
else
exception.printStackTrace();
});
If I change the “MAIN.E_Lum_1:BOOL” to a value that doesn’t exists I get a error saying me the name is invalid which is fine and tells me its really communicating with the PLC.
Now, when using the good name, I don’t get an exception and I see thee “WRITING DONE…” in the console. However, the value is unchanged in the Beckhoff PLC.
Is there anything I don’t understand ??
Thank you very much !!!

Subject: AW: TwinCAT ADS - Write value to PLC
Hi Patrick,
I thought I had tested writing of values via ADS … will re-test.
But when writing you have to be sure the PLC doesn’t overwrite this value internally.
I remember when I tried „overriding“ outputs of PLCs with a written value. In the end it turned out that the value was overwritten, but the PLC program just set it to it’s original value as part of the program execution.

Betreff: TwinCAT ADS - Write value to PLC
Hi all,
I’m using the TwinCAT ads driver with the 0.8.0 realease of PLC4X. I can read all the values from the PLC without issue, but writing doesn’t seem to work.
I don’t know what Im doing wrong.
Here is the writing code:
PlcDriverManager driver = new PlcDriverManager();
try {
PlcConnection plcConnection = driver.getConnection(
"ads:tcp://10.10.11.77?sourceAmsNetId=172.29.64.1.1.1&sourceAmsPort=32&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");
if (!plcConnection.getMetadata().canWrite()) {
return;
}
PlcWriteRequest.Builder builder = plcConnection.writeRequestBuilder();
builder.addItem("lightToggle", "MAIN.E_Lum_1:BOOL", true);
PlcWriteRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
if (exception == null)
System.out.println("WRITING DONE....");
else
exception.printStackTrace();
});
If I change the “MAIN.E_Lum_1:BOOL” to a value that doesn’t exists I get a error saying me the name is invalid which is fine and tells me its really communicating with the PLC.
Now, when using the good name, I don’t get an exception and I see thee “WRITING DONE…” in the console. However, the value is unchanged in the Beckhoff PLC.
Is there anything I don’t understand ??
Thank you very much !!!
Here’s the Beckhoff PLC setup:
