Omron DR 170 14 manual To delete device groups, To configure default update intervals

Klinkmann Automation Omron Ethernet DAServer 27

If Memory Area Read is checked (default setting), then Server uses Memory Area Read FINS commands and maximum (Read FINS Message Maximum Size – 14) / 2 consecutive words can be read from this Controller by one read command.

If Multiple Memory Area Read is checked then Server uses Multiple Memory Area Read FINS commands and maximum 128 non-consecutive words (also from different memory areas) can be read from this PLC by one read command.

Note: Even if Multiple Memory Area Read is configured - several memory areas are still accessed by general read commands.

If Single Write option is checked, then for each new write value a separate write message is created. The values in the PLC are changed by the DAServer in the same sequence as they are changed in the user (client) application. With this option the data update rate is low if application changes values very frequently, but sequence of value changes are guaranteed.

If Last Msg Multiple Write option is checked, then the same message can be used for the writing of new values into the consecutive memory addresses of the same memory area (for example, into D0, D1, D2...). Up to 124 consecutive values can be included in the same write command. The new value can be added only to the end of last write message. Therefore some values may be written into the PLC memory simultaneously even if the client application changes them step-by-step. With this option writing speed can be seriously increased, and sequence of value changes are partly guaranteed (several new values could be written into PLC memory simultaneously while application change it step-by-step). For example, the client application sequentially changes the values of following 248 items: D0, D1, ... , D247 and the values of following 248 items: 500R, 502R, ... , 994R. In this case the DAServer creates only four write messages to write the new values for all the changed items. If the values of the same Items are changed in the following sequence: DM0, 500R, DM1, 502R, DM2, ... then DAServer creates a separate write message for each new write value.

If Any Msg Multiple Write option is checked, DAServer tries to include the new write value into any of previously created messages ignoring the sequence of data changing in the client application.

Important! With this option maximum writing speed is achieved, but this option is not recommended if data changing sequence is important for PLC program!

To delete device groups

Deleting a device group from the list can be performed as follows:

1.Right-click on the device group to be deleted.

2.Select the Delete command from the shortcut menu.

Note: When you select another part of the Omron Ethernet DAServer tree hierarchy, you are prompted to save the modifications to the configuration set.

To configure default update intervals

1.To configure a default update interval for the object, right-click in the Device Groups box.

2.Select Config Default Update Interval from the shortcut menu.
