HART-enabled I/O Modules
PointMax analog HART I/O modules have built-in HART modems, so there is no need to
install external HART multiplexers or clip-on HART modems. The modules have separate
HART modems for each channel.
HART implementation in PointMax analog HART I/O modules provide a connection between the
controller and each HART device.
A HART device that is connected to a PointMax analog HART I/O module supports both
connected and unconnected message instructions.
The configurable connection to each HART device can support:
- Up to four Dynamic Variables
- Up to eight Device Variables
- Up to four HART commands
For connected messaging:
- Up to two concurrent Class 3 connections are supported for every HART device.
- Up to 16 concurrent Class 3 connections are supported for the HART module and all attached HART devices.
For unconnected messaging:
- Up to two concurrent unconnected messages are supported for every HART device.
- Up to 16 concurrent unconnected messages are supported for the HART module and all attached HART devices.
