15.1.3.3 2 Channel Analog Input Modules HART
750-482, -484, (and all variations),
753-482
The HART I/O module provides two different process images depending on the
set operating mode.
For the pure analog values 4 mA ... 20 mA, the HART I/O module transmits 16 bit
measured values per channel as an analog input module, which are mapped by
word.
In operating mode "6 Byte Mailbox", the HART I/O module provides the fieldbus
coupler / controller with a 12-byte input and output process image via a logical
channel. For the control/status byte and the dummy byte, an acyclic channel
(mailbox) for the process value communication is embedded in the process
image, which occupies 6 bytes of data. This is followed by the measured values
for channels 1 and 2.
HART commands are executed via the WAGO-IEC function blocks of the
"WagoLibHart_0x.lib" library. The data is tunneled to the application via the
mailbox and decoded by means of the library, so that the evaluation and
processing takes place directly at the application level.
The operating mode is set using the WAGO-I / O-CHECK commissioning tool.
