∙Target Scan Time

A time factor for limiting the time assigned for the Message transmission. The actual Scan time (time of Token passes all stations) is either longer one the Target Scan time or time for Scan transmission. (see Apendix A.1)

The Target Scan time should be the same value in all stations connected to the S20LP network (layer). The Target Scan time can be selected from the combo box, select the target cycle time you want to set. Click on the "OK" or "Renew" button. The data you set is transmitted to the corresponding station.

3.07 8.19 13.3 24.6 45.1

4.10 9.22 14.3 28.7 49.2

5.12 10.2 15.4 32.8 53.2

6.14 11.3 16.3 36.9 57.3

7.17 12.3 20.5 41.0 61.4

(Note 1) If Message transmission cannot work normally or a S20LP-station becomes Error down by Receive buffer overflow, the time for Message transmission is not enough. In such case, increase the Target Scan time value.

When the settings are correctly written into the S20LP-station's EEPROM, it is displayed on the screen as below.

(6)Change connection to other stations, and repeat (2) to (5).

S-LS remote setting (without changing connection) is also available by selecting the station number. In this case, change the station mode to "STANDBY" by S-LS before setting. After all setting complete, change the station mode to “ONLINE” by S-LS.
