General description
The T501 is DIN rail module for interfacing HART instruments to a PROFIbus DP network.T501 is a complete transmitter module. It allows interfacing up to 4 HART instruments.
It generates a measured variable including a status variable indicating the quality of the measurement.
T501 supports the DP V1 protocol and PA Profile 3.01
T501 includes a HART master in order to communicate with a HART instrument. The module reads the variables from the instrument and converts this to a dynamic variable on DP. Four AI Function Blocks are supported. Other Function blocks can be added on request. The HART slaves are supposed to work in multidrop mode
The Primary Variable (PV) will be continuously read and updated. Any HART communication problem will be reported in the PROFIbus Diagnostics message.
The HART Universal command parameters are available from the DP side
Applications
The T501 is intended for integration of existing HART instruments into PROFIbus DP network. It is intended for system integrators
that are building PROFIbus based systems.
PA functionality supported:
- Alarms
- Low pass filtering
- Unit conversion
- Range
- User calibration
- Diagnostic information
No special programming is required to set up the device.
