Support Questions / Reading DINT.bit returns bit position value, not true/false (v3.97c)

Same for INT, DINT.

For example: Read(IntegerTag.1) will return 0 or 2. I would expect 0 or 1.


AdvancedHMIDrivers.EthernetIPforCLXCom connectionAdvancedHMI;
connectionAdvancedHMI = new AdvancedHMIDrivers.EthernetIPforCLXCom();
... connecting and validating other read/write operations ...
connectionAdvancedHMI.Read("IntegerTag.1");

Support Questions / Bit write with Logix ethernet / How to get data type from Read()

« on: January 16, 2015, 05:11:41 AM »

Hi all,

To make this work I have the following solution, that unfortunately does not work for INT.bit, only for DINT.bit. Is there a way to get the datatype from the driver read response? Then I can do it right.

The CIP message should as I understand it (1756-PM020A-EN-P, page 12) report the datatype, so it would be nice to be able to get that one too when calling AdvancedHMIDrivers.EthernetIPforCLXCom.Read().

This is my current solution, not usable for INT - only DINT.
1. Detect if the tag has a dot suffix - Tag.x
2. Read Tag as DINT and bit mask to desired value
3. Write tag as DINT
