Functions of the HART Analog Output Module Detailed Description of the Module
HART Analog Output Module ME1DA6HAI-Q 3 – 7
*1 A watchdog timer error occurs when program operations are not completed within the scheduled time due to a hard-
ware problem of the D/A module. In this case, the module ready signal (X0) and the D/A module RUN LED are turned off.
*2 The rate control and scaling function is activated.
*3 HART communication will be stopped without notification for output currents lesser than 2 mA. It will recover automati-
cally if the output current is 2 mA or higher again (refer to section 3.5.16).
