pj1995 Posts: 24 Rating: (1)	Hello, I'm using a V90 drive for basic positioning with SINA_POS in tia portal. I try to program a OFF3. The OFF3 is located in: SINA_POS_DB.sxSendBuf.STW1 (bit 3 from the control word) but I can not acces it via DBX0.3 can someone help me with this? Thank you

OFF2 and OFF3 are preassigned 1 using input "ConfigEPos" – and do not have to be written to for operation https://support.industry.siemens.com/cs/ww/en/view/109475044

pj1995 Posts: 24 Rating: (1)	Hello, Thank you for your help, but I have V13 of TIA PORTAL. The ConfigEPos is something new and came with V14. I want to reset OFF3 with the PLC when I press E-Stop. The E-STOP signal comes from a safety relays from PILZ via profinet (I know it's not safe but that's ok ). I know the OFF2 and OFF3 are automaticaly set when enabeling the axis. Kind regards, PJ

pj1995 Posts: 24 Rating: (1)	Hello, Is this a good way to reset the OFF3 bit? since the OFF3 is the 2nd bit of the word, I multiplied the word with 1111111111111011(16#FFFB). Attachment sina pos.PNG (414 Downloads)
