About Value Transformation Filters
The SNVT settings registered in the tag properties are intended to process data obtained from LON so that it is easy to handle on the client side. If "default" is selected, no processing will be performed. If anything else is selected, the data will be processed.
For example, if you select "SNVT_switch", when reading a value, if the raw data is "100.0 1", the value will be TRUE, otherwise it will be FALSE. When writing a value, if you write FALSE, it will write "0.0 0", and if you write TRUE, it will write "100.0 1".
These specifications are not published as standard specifications. We provide paid support for customizing these conversion filters. Please contact us for details. |
default (Handle raw data as is)
SNVT_switch (handled as a Boolean value)
By adding options after the item name, you can specify the communication method for Lon. This is a LNSDDE Server specification, so please refer to the LNSDDE Server manual for details.
