Figure 2-2 Honeywell Analog Value Scaling
Digital (Communications Signal) Input/Output
As indicated at the right of Figure 2-2, communications between the MC Toolkit and the Honeywell
Smart Transmitter consist of digital pulse strings, with rapid transitions of current level between
(approximately) 4 mA and 20 mA.
CAUTION:
These rapid transitions provide for effective communications, but will interfere adversely
with a transmitter operating on-line in a control loop.
The MC Toolkit communicates digitally; exercise caution and good judgment when
connecting the unit to an on-line transmitter operating in the analog mode.
