Activating PLC Output at the specific time - please help
MRPLC82 posted a topic in Allen Bradley / Rockwell AutomationEvening, I struggle with simple task... I need to activate PLC Output at the specific time of a day. I`m using GSV to obtain PLC time, data is being moved to DIN registers. Then I have three EQU (Hour / Minute / Second) and at the end of rung there is OTL for output. Rung below I have two EQU (Hour / Minute) to disable output at different time - OTU. However every time OTL is energised , OTU on rung below is fired too. What am I doing wrong here ?
CompactLogix WallClock misreporting
TL7791 posted a topic in Allen Bradley / Rockwell AutomationHello all, I am experiencing an unusual (and what appears to be an unheard of) behavior in my CompactLogix L18ER controller. I am setting the date/time of the controller from my work station, however when I GSV WallClockTime, it is reporting 4 hours different. I have asked our local resources as well as done some forum and knowledgebase searching without result. Has anyone encountered this before? Attached is a screenshot of the controller time vs. the wall clock time. This isn't mission critical since it can be manually adjusted however I would like to understand what is taking place that would cause this behavior. Thanks!
