Hi Lukas, went through the video mentioned. But I didn't get which siemens simulator they used for demo? Can some one let me know free siemens s7 plc simulator for poc purpose?

Re: [Modbus] Querying Values from Holding Register
Hi.
In this branch you can find the modifications to the Modbus 0.6.0 driver to
read scalar types from the same requested field.
https://github.com/glcj/plc4x/tree/s7alarm
In the future we must follow the new driver model 0.7.0
I hope it is useful for you,
Best regards,

RE: [Modbus] Querying Values from Holding Register
Hi Chris,
yes, I use the 0.6.0 version.
Great, I will try to do it again when the new version is available and let you
know whether it works.
Thank you very much!

Hi Tim,
I guess you are using one of the "old generation" drivers (As you say it's
working and the address seems to imply that).
Perhaps you should either try the version 0.8.0-SNAPSHOT or wait for 2 more
days till we release the 0.7.0 version.
In the 0.7.0 version we have completely deleted all existing drivers and
replaced them by new ones.
While at it I took the liberty of making the Modbus a little more robust.
So it would be great if you could give us feedback if your problem goes away
magically when updating to these driver versions.

For Boolean values in the coil this works without any problem (using

Can you give me an indication of what my problem may be or what I'm doing

[Modbus] Querying Values from Holding Register
Hi all,
I have tried to query values from the holding register of a simulated modbus
device and process them as integer using the following code:
// read integer / holding register
PlcDriverManager driverManager = new PlcDriverManager();
String conString = "modbus:tcp://localhost";
PlcConnection plcCon =
driverManager.getConnection(conString);
PlcReadRequest.Builder builder =
plcCon.readRequestBuilder();
builder.addItem("value", "readholdingregisters:1");
PlcReadRequest readRequest = builder.build();
PlcReadResponse resp = readRequest.execute().get();
This runs well, but when I try to handle the result as integer (using
resp.getInteger("value")) I always get null as result no matter what's in the
register.
For Boolean values in the coil this works without any problem (using
getBoolean() of course).
Another approach I tried is using the getAllByteArrays("value"); command, but I
haven't found a way to get the returned collection of byte arrays into integers.
Can you give me an indication of what my problem may be or what I'm doing wrong?
Thank you very much in advance!
