  • CitectSCADA 2.01
Summary:
Support for REALs in the Modbus and Modbus Plus protocols was added between Citect for Windows versions 2.01 and 2.10. The initial version of these drivers did not support the real format correctly causing garbage values to be read from the PLC.

CIT has confirmed this to be a problem in Citect for Windows versions 2.01. This problem has been fixed in version 2.10 and later.

 

Solution:
Use version 2.10 or later or get the updated Modbus or Modbus Plus driver from Citect Support.
