General description
The T511 is DIN rail module for interfacing MODbus instruments to a DP network.T511 is a complete transmitter module. It allows interfacing up to 4 MODbus instruments.
It generates a measured variable including a status variable indicating the quality of the measurement.
T511 supports the DP V1 functionality and the PA Profile 3.1
T511 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 FF. Four AI Function Blocks are supported. The location of the MODbus registers and data type of the MODbus variable can be configured.
The Primary Variable (PV) will be continuously read and updated. Any MODbus communication problem will be reported in the PROFIbus Diagnostics message.
Applications
The T511 is intended for integration of existing MODbus instruments into PROFIbus DP network. It is intended for system integrators
that are building Fieldbus Foundation based systems.The physical interfaces to the MODbus instruments is
RS 485
PA functionality supported:
- Alarms
- Low pass filtering
- Unit conversion
- Range
- User calibration
- Diagnostic information
