I was able to rectify my problem with help from Posital support. It seems the issue is on the TIA Portal side. Summary for everyone’s notice: I have a posital Linear sensor (string encoder).https://www.posital.com/en/products/linear-sensors/linarix-product-finder/LD0-EIC1B-1216-2P00-PRM/222864701/detail.php I am using an Encoder Technology Object and the “LAxisCtrl_ExtEncoder” in siemens to interface with the encoder. I am using standard telegram 83 The Resolution for the encoder is 1216. 16 bit singleturn and 12 bit muliturn thus 28 bit total.
These values are mostly set in the hardware configuration. (attached screenshot) In the technology object the settings are (also see screenshot):
The last two are the key that I was missing. The posital rep said that she has seen it before where TIA misinterprets something from them and those resolution bits (which I would think need to be 12 and 16) MUST be set to 0. Result: After setting those two parameters to 0 bit I am able to cycle power without losing position AND move the encoder with power off without losing position |
