[jira] [Commented] (PLC4X-45) [Modbus] Make the modbus driver support reading and writing of all or at least most plc4x datatypes

["Alvaro del Castillo (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PLC4X-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16994304#comment-16994304 ] 

Alvaro del Castillo commented on PLC4X-45:
------------------------------------------

It also support LONG. According to the comments of the driver inside the code:

https://github.com/apache/plc4x/blob/develop/plc4j/protocols/modbus/src/main/java/org/apache/plc4x/java/modbus/messages/items/DefaultModbusByteArrayFieldItem.java#L215

{noformat}
    //ToDo: Implement conversion for Float and Unsigned-Datatypes

    //ToDo: Add exceptions to avoid unwanted states --> e.g. neg indexes
{noformat}

In our modbus plugin we have implemented unsigned types (except float) and also signed float. My plan is to send PRs with the code.

The first one will be for float support.

> Currently it seems as if the Modbus driver only supports reading BOOLEAN, INT, SHORT and BYTE ... however we need to make it possible to also support others as the developer might combine neighboring fields.
