Logging Data from a Siemens PLC into Excel
JBird1229 posted a topic in SiemensHey guys, I know this is a topic that has been discussed before, but I am having trouble finding exactly what I am looking for.. I want to know the most efficient way to record data from my PLC to an Excel file on my PC. I want this to be done without the use of the PLC's webserver. Specifically I am trying to record vfd speed every 10seconds with a time and date stamp. How can I do this? Thanks, James

Sysmac HMI Date Time Button
DrMaryStone posted a topic in NJ Series / Sysmac StudioI'm very new to sysmac. I am trying to display the current date and time in the corner of each of my HMI pages. I saw a button labeled date and time. It is asking for a variable for behavior. Do I need to write some basic structured text or FB in plc to get date and time and pass it over? I figured the button would update itsself since when I placed it on the screen it had the current date and time and refreshes every time I leave the page and come back.
Capture Date and Time
AlanJ posted a topic in CX-ProgrammerI would like to capture current date and time to registers in the PLC. I would prefer to use a function block, if possible, since I need to do the capture at different places in the program. I am using a CJ2M. How can I do it?
Date and time data type in GX Works2
M_ah posted a topic in MitsubishiHello, Completely new to Mitsubishi PLCs and I need to use a date and time stamp for data collection purposes. We have a Siemens PLC as well and this has the data type "Date_And_Time" which is what I need to replicate. I have been attempting to write my own data type but am struggling with how to go about this as it is not straightforward and I cannot find anything about how the Siemens Date_And_Time is made up so I have nothing to go off. Does anyone have an example of a data type they have made that is the same? Or is there a data type which does this already in GX Works 2 that I just can't seem to find? Please help!

Handle dates in cx programmer
Morten posted a topic in CX-ProgrammerHi I'm all new to using omron but "stuck" with a project. I find the CX Programmer software (version 9.35) a bit confusing. Used Siemens a lot. What I'm trying to do is to display date and time on a HMI showing cpu startup time. I use a "First cycle flag" that triggers once when CPU starts and then I understand that the date and timestamp is in the system variables A352 and A353. But how do I format them as a normal text? I only manage to display them as #hex-numbers. I have tried googeling but have not found an answer to my questions. edit: CPU type is: CJ1M CPU12 //Morten

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!
