The intention of this presentation is to provide some suggestions for practical and workable configurations for E900 HMI that will give adequate performance while allowing use of most of the features of this HMI to be used.

E900/E910

Configuration possibilitiesIt is possible to configure the following ……..

Every screen with a six pen historical trend logging data at 1 second intervals.Screen updates and data polling at 1 second intervals.Trend printing.HMI tools data uploading.Transparent mode.All screens with greater than 100 live update multi-symbol objects.HMI to HMI networking.

E900/E910Configuration possibilities (cont.)Clearly it is not possible to do all these things at the same time.An E 900 was never intended to have a full multitasking operating system, otherwise it would probably have been based on Windows CE.If you want more of one feature you can have less of another feature. It’s a balance.

Notes on printingPrinting is in black and white only which means that it is hard to distinguish traces on a trend. Use of white on black helps with this.Printing can be configured to the serial port but it is better to use the parallel port option card.Support for FX80 (dot matrix), HP PCL5, HP PLC5e, and HP PCL 6.Printing can be slow (especially via the serial port) and it slows down the HMI while printing.Printing at the same time as an HMI tool file transfer on the same serial port will fail the file transfer. Use of the inhibit alarm printing feature linked to a PLC register can resolve this.

Notes on HMI Tools

For large file transfers it may be necessary to increase the HMI Tools timeout setting (max. 9999).During a file transfer the HMI will slow down.HMI Tools version 1.11 should be used at all times together with latest versions of I/O drivers.

Notes on TrendingTrending can be set to poll for data at a maximum rate of once a second however this imposes a heavy load on the HMI and this level of performance cannot be guaranteed. I.e. during file transfers, printing, and transparent mode the communications may slow down.It is recommended to set trend data rates at the slowest possible speed to satisfy the application.To save memory and increase performance, historical trend data will only store values when they change. In version 5 it is selectable to store all polled values.

E900/E910

Notes on Trending (cont.)Historical trend data occupies HMI memory according to the following formula.

– S = TOS + AK(28 + (654 + ((AS / 100) + 1)))Where: S = number of bytesTOS = Trend Object Size, if all parameters for a trend are changed, the TOS = 320 bytesAK = Number of trend pens (traces / curves)AS = Number of samples rounded to the nearest 100.

The maximum number of stored values (samples) for each historic trend pen is 4800 in versions up to 4.03 and 13,000 in version 5.

E900/E910Notes on display screen designIt is recommended that no more than 30 live screen update points are put on any one display if a one second screen update is required. (60 live update points can take 1.6 seconds to update).If the HMI is a network Client it may be necessary to have fewer than 30 live screen update points per screen.
