Hello,

I am using TIA V17, where within I have added a CPU1511F-1PN: the aim is to control a Simatic G120C VFD having the following article ID: 6SL3210-1KE12-3UF2. The PLC is downloaded via Siemens virtual Ethernet switch onto PLC Sim Advanced V4 (virtual PLC). As for the drive, I have it physically connected within the same network band of the virtual PLC. 

From the TIA VM, I can ping both, the virtual PLC as well as the drive. Using PRONETA, I have set the IP address of the drive, with the following crop representing its internal firmware version:

In TIA, below is its FW version:

According to this website:  the V4.71.52 represents the firmware version of 4.7.13:

For now, there aren't any communication/FW issues. Below is the TIA network view:

As a reminder, I am using a virtual PLC with a physical Sinamics drive. After running the commissioning wizard of the drive in TIA, and setting its Telegram configuration, etc. the moment I download the settings onto the drive it tells me the following: "Maintenance demanded, error in lower level component".

Below are some parametric views:

The keynote is that I am NOT inputting any 3ph as input to the drive, neither a 3ph motor terminals connection to it. The purpose at this level is to only check some data traffic between the PLC and the drive, such as the states of digital inputs, and the value in the analog input, etc. 

No executive switching/control of the motor is intended at this stage. I also do not know, if the absence of the phase input/output put the VFD in such state.

For example, the values inside the Status word 1 and Status word 2:

can be seen on the HMI that is connected as an accessory onto the device, but NOT seen in the Telegram assigned addresses according to the Telegram setup...

Any further guidance would be greatly appreciated...

From the alarm buffer of the drive, you can see what is causing the error.

 Hi Hati,

Do you mean the missing enable signals?

Are they "missed" autonomously when there aren't any input feeding power/motor wiring?

Other VFDs (such as Schneider) have the option to "ignore input/output phase loss", where if set, you can still control different regions of the drive than the switching, such as reading AI and DI.

Is that possible with the G120C?

 If you have an error in the lower level component, you can see the error from the devices alarm buffer.

You will have an alarm, if you try to run the VFD and there is no line power or motor connected to it.

As long as you have 24vdc connected to the drive, you can read inputs (digital and analog).

 Well thanks for the tip Hati!

So I have the physical VFD, linked in TIA where I can activate its Control panel testing area, but NOT able to communicate with it in send/receive directions. The first indicator is "lower level component error" that when "solved" I should receive data from the drive (correct me if i'm wrong).

I don't know what you mean with "devices alarm buffer", if you can please straightforwardly point at it, and help to actually "remove" the causal of error.

If what you mean with "devices alarm buffer" is already posted as an image in the initial post, you just can point at it so I can try to read and understand what is happening. 

According to your first reply, it seems that you have already identified the error in the lower level component, so most beneficial if you can please guide on how to reset it...

Every device you have in the project, has a section called Online & Diagnostics under them in the project tree. From there you select Diagnostics -> Active alarms or Alarm buffer. From those you can see what active alarms you have in the device.
