Posted 10 Nov 2016 I have1756-16F & 1756-IF16H analog input module connected to my contrologics 5572 controller. there is only single sensor connected few days ago & it the channel where sensor is connected was showing data without any channel fault but others were showing channel fault even if now sensors are connected & no data is coming ...checked with mA source then in 1756- IF16 the channel 0 to channel 8 (total 9) channels are showing data in the system & The 1756-16H hart card is not showing any data for new sensor it is also showing channel fault.It is even not showing any reading when connected to mA source.I have checked wiring it is as per single ended configuration & in module properties I have selected the same.How should I clear this fault ? What was the reason behind it...Dear friends plz give your valuable suggessions. The ScreenShots of the raw data & channel status are attached here please see Share this post Link to post Share on other sites
Posted 11 Nov 2016 The channel fault is occurring because there is no valid (in range) analog data. The card senses when the analog point is not connected. Share this post Link to post Share on other sites
