Hi Jairo,
You should be able to read tags from an S7-1500, but what do you mean by symbolic directionality?

Hi.
There is two ways to direct tags in s7-1500 and s7-1200.
Symbolic direction : Motor 1; Motor 2; Motor 3:
Absolute direction: Db2.dbx1.0; db2.dbx1.1; Db2.dbx1.3:0 -
Hi Jairo,
From what I've seen looking through the documentation it seems like you're able to poll tags but you need to follow the restrictions on page 19 in this doc

It looks like you also need to make sure that you make sure that there's a setting checked in TIA on the bottom of this link:

is the check box the Put/Get security?

You need to allow access with PUT/GET in TIA Portal in the "General" tab, under "Protection & Security > Connection mechanisms".

Also, here is Siemens doc which explains how to do this (see page 9 - 10):

No is not possible; you must use DB non optimized, only direct memory access like in the S7-300;
for the future, probably siemens remove the put/get option from the s7-1500, so you can access only via opc-ua client.it's time to think to develop in ewon a io-server native for the S7-1500 :
