Description
T410 includes a MODbus master in order to communicate with a MODbus instrument. The module reads the variables from the instrument and converts this to a dynamic variable on PA. Four AI Function Blocks are supported. The location of the MODbus registers and data type of the MODbus variable can be configured. Other Function blocks can be added on request.
Applications
The T410 is intended to be integrated into MODbus instruments that shall be upgraded to interface to PROFIbus PA
Power options
