Logging the BIOS and serial numbers of TM172E28R and TM172EVEV1U

[obscuresc]

Hi,

I am using a TM172PDG18R (PLC) in conjunction with an IO expansion (TM172E28R) and a unipolar stepper driver (TM172EVEV1U).

I'd like to be able to log both the BIOS and serial number of all them via a single connection to the PLC. The stepper driver has the serial number listed in parameters, but not the BIOS. The expansion module has neither, likewise with the PLC.

How can I get access and read these parameters?

I am using EcoStruxure v1.5.0.

Cheers.

Hello,

unfortunately these info are not available.

You can only read them with ESME HVAC using a DMI connection (USB-ttl converter used to program M171O).

The FW of the I/O expansion is quite stable, I don't remember the last update.

Ok, cheers.
