Useful to clarify the meaning of an alarm.-This Information will be included in the email that you can send on alarm.Table 43: Tag’s general properties controlsI/O Server SetupServer NameTopic NameAddressTypeForce Read OnlyeWON valueThe IO server name is the Data source of the Tag name. Six data sources are available:‘eWON’ for all the eWON internal IO (please refer to chapter “The eWON IO Servers” on page 85)‘MODBUS’ for IO located on the extension bus (please refer to chapter “Modbus IO server” on page 88)‘MEM’ for virtual IO used by script function (please refer to chapter “MEM IO Server” on page 124)‘NETMPI’ for IO located on the extension bus (please refer to chapter “NETMPI IO Server” on page 94)‘UNITE’ for IO located on the extension bus (please refer to chapter “UNITE IO Server” on page 96)‘DF1' for IO located on the extension bus (please refer to chapter “DF1 IO Server” on page 100)‘FINS' for IO located on the extension bus (please refer to chapter “FINS IO Server” on page 106)‘S5-AS511' for IO located on the extension bus (please refer to chapter “S5-AS511 IO Server” onpage 110)‘S73&400’ for IO located on an MPI bus (please refer to chapter “S7-300&400 (MPI/Profibus - ISOTCP)”on page 125)‘S7200’ for IO located on an PPI bus (please refer to chapter “S7-200 (PPI - ISOTCP)” on page 130)Used to apply a common configuration to several Tags.Please refer to chapter “Tag definition: Introduction” on page 67Please refer to chapter “Tag definition: Introduction” on page 67Note: for memory Tag (MEM IO server) this field can be left empty. Although when editing a memory Tag,the Tag Name will be found here, this field is insignificant.Defines the Tag name type: Analog or Boolean. Analog enables the Tag to take float values coded on 4bytes.Boolean only return value 0 or 1. If the IO server returns a value equal to 0, the Boolean value is 0. If theIO server returns a value different from 0 the output value is 1.Allows the disabling of the Update function in the View IO page. This is useful if you want to monitor aread/write Tag. The Tag is still read/write for BASIC operations.Defines the offset and scale factor to be applied to the IO value coming from the server. The offset andscales are float values and negative values are accepted. The Tag value will be: TAGval = IOSERVERval* scale + offset.Table 44: IO server configuration controlsRG-001-0-EN ver 1.5 eWON® - 20/03/2009 - ©ACT'L sa Page 72
