islam elamrawy Posts: 7 Rating: (0)	I havea problem with Ultramat 23 analyzer. The analog output of the analyzer is connected to PCS7 system via analog input cards SM331. All four analog readings are ok in analyzer but it gives bad quality error (for second then return ok again)in pcs7 system while the reading are ok (no open loop values).I made test for the analog output of analyzer from its menu and measured with multi-meter and values are ok. Can you help me with this problem? Regards
