Connecting Kepware with Siemens PAC3200 using Modbus TCP/IP

Connecting Kepware with Siemens PAC3200 using Modbus TCP/IP

Hello Developers,

We are facing some problems trying to connect the Siemens power monitoring device "PAC3200" with KEPserverEX 6.5, using the Modbus TCP/IP protocol, the basic configuration are done using its manuals (attached) but we still have a Bad Quality in the tags.

This is basic configuration for the device:

 

Device Configuration.pngDevice Configuration

For the tag:

Tag Configuration.pngTag Configuration

Just a tag example from the PAC manual:PAC3200 Tags.pngPAC3200 Variable

This is a variable that we can use the function code 0x03 and 0x04 (page 40).

I tried to use the address 400001, 30001, 300001, disable the zero-based-addressing, modbus-byte-order and nothing works. 

Note: I can ping the device with no issues.

 

Kind Regards.

Hello Claudio,

 

This device probably has a station/node/slave address assigned to it. For example the SquareD power meters have a default station address of 7 so you would use this in place of the default '0' in the Device ID, making it "<172.17.31.156>.7" .
The Siemens configuration software should indicate in some way what that station/node/slave ID is.

 

Best Regards,

KC

Hello Mr. KCorrigan,

You were totally right!!

It's working now! The ID 7 was the right ID.

Thank you very much for your support!
