Hi, does anybody know how to count total running time for a process in SLC 500? I like to know how long a process takes from the beginning to the end.  The process running time is different from a batch to another.  The counting begins by a switch and ends by a condition. Assuming total running time is 10000s, how is this number converted to a format for HH:MM:SS? Thanks.

Thank you, b_carlton and Godra. You are very helpful.  I tried it and it works.  I am going to use Kinco HMI MT4532TE.  Now, I have to figure out how to display the string on that HMI.

Hi, I am trying to interface SLC 500 and HMI with text.  Can anybody help me how to program in RSLogix 500 with text? My problem is :   When switch 1 is on, PLC will write a text or move a predefined text "IN PROCESS" to a file N15.   When switch 1 is off, PLC will write a text or move a predefined text "IDLE" to a file N15.   When switch 1 is on and output relay 1 is on, PLC will write a text or move a predefined text "DONE" to a file N15.    Then, I like to display the text  in a status box on a HMI at real time.  During the process, the text should be changed based on the status automatically.  Is it possible?  If it is possible, can anybody give me some kind of examples?  Thank you for your help.

Hi, everyone.  I hope your experts can help me on this.  I have a SLC 500 with 5/03, 1746-IB16 and 1746-NO4V. I like to use a switch to input in 1746-IB16 channel 1.  Once that switch is on, I want 1746-NO4V channel 1 outputs a voltage say 2.5 V.  I can modify the OUTPUT File to output that voltage, but not safe for running the program. Is it possible to use a digital input to generate a voltage output from an analog output module?  If that is possible, what kind of function I have to use in the program?  Thanks a lot.
