To read actual value from PLC, you can add extension to communication telegram and add p752 (mA/V) or p755 (%) to this extension. Or, because temperature has no quick changes, you can read parameter values acyclicaly using SinaPara block, integrated in TIA portal (under Instructions - Optional packages - Sinamics). For Step7 also exists block for acyclic communcation with Sinamics drives. See this application example for details. With regards Martin
