How to write datapoint to IEC driver: IGQ

[giorgiob]

From Para, I defined a datapoint with IEC driver peripheral address (112.0.1.5.0.1), output direction, address active.

After the connection with peripheral unit is achieved, my control script starts IGQ:

dpSet("_Driver2.IGQ", "conn1.112.0.1.5.0.1");

Even if from Para I can see _Driver2.IGQ original value properly written with address pattern, no writings in control direction are sent from driver to RTU (I checked it with wireshark protocol sniffing).

Can you help me?

To check if the IGQ works you can first use the pattern "*" at the IGQ element to send all values to the PLC, if this is possible and does not cause problems on the plant if the PLC receives all values.
If this works you can try it with patterns in the address string you are using, possibly the string is wrong and therefore it does not work.
When the debug flag "-dbg 2" is activated for the driver you can probably also get information in the logfile which helps to find the problem.

Hi Leopold, thank you for your suggestion.

I tried with wildcard patterns:
"*"
"*.0.100.4.0.1" and "*.0.100.8.0.4"
and it works. Here is the partial log:

As far as I know the pattern must match the information you get when reading the attribute _address.._reference.
if this information is used the IGQ should work.
