Graham, I have written a TRNSYS TYPE I call the "Equipment Monitor" that does what you require, along with several other things. You (and everyone else in the TRNSYS community) are welcome to use it. The relevant files are attached in a zip file, and some notes on it are given below. Kind regards, Todd --------------------------- EQUIPMENT MONITOR (TYPE206) INPUTS: For any number of controllers/equipments the Equipment Monitor takes two inputs: - Switch: Whether the equipment is on or off - Level: For example, the load power for a diesel generator OUTPUTS: For each controller/equipment the Equipment Monitor gives the following outputs: - Number of uses (i.e. number of times switched on) (GRAHAM: I believe is what you are after!) - Total time in use - Mean period of use (= total time in use / number of uses) - Longest period of use (longest time between being switched on and switched off) - Shortest period of use (shortest time between being switched on and switched off) - Mean level (average level when switched on) - Maximum level (greatest level when switched on) - Minimum level (least level when switched on) HISTOGRAM DATA: In addition to the outputs above, the Equipment Monitor can also produce histogram data, which can be quickly and easily plotted in Microsoft Excel (or similar). It produces both frequency and cumulative frequency data of the equipment levels while the equipment was switched on. The data is exported as comma separated data to an external file, which may be opened in Microsoft Excel (or similar). To use this feature: - Set the "Give histogram data?" parameter to 1 - Select the number of points you want on your histograms - The "LU" parameter is used as the logical unit for the external data file. You can usually leave this set to the default value of 206, but you may need to change it if you already have another file assigned to this number. - Select the external file where you want the data to be written IMPORTANT NOTE: The histogram option can cause the simulation to take a long time to run. All of the processing for it is done after the last timestep, so you may experience a long pause between the simulation reaching 99% complete and the actual end of the simulation. If you don't require histogram data then it's best to switch this option off by setting the "Give histogram data?" parameter to 0. HOW TO INSTALL: 1) Copy Type206.dll into \..\Trnsys16\UserLib 2) Copy Type206.bmp and Type206.tmf into \..\Trnsys16\Studio\Proformas or an appropriately named subfolder. 3) In TRNSYS Simulation Studio, select "Refresh Tree" from the "Direct Access" menu. The component should now appear in the access tree in Simulation Studio as "Type206" All feedback is welcome! My contact details are below.
