General warning sign General warning of a danger zone. Hot surface Warning of hot surfaces, e.g. possibly caused by high ambient temperatures or strong direct sunlight.
Actuator controls AC(V) 01.2/AC(V)ExC 01.2 HART General information on HART General information on HART 2.1. General information on HART HART (Highway Addressable Remote Transducer) is an open communication protocol allowing bidirectional data exchange between DCS and field devices on the basis of analogue 4 20 mA signals.
Actuator controls General information on HART AC(V) 01.2/AC(V)ExC 01.2 HART Figure 2: Services and diagnostic data 2.2. Basic characteristics The HART interface superimposes and transmits all actuator parameters adjustable and legible via local controls (e.g. for commissioning, diagnostics, status signals) as digital instruction (command = write parameter, request = read parameter) to an analogue input or output.
Actuator controls AC(V) 01.2/AC(V)ExC 01.2 HART General information on HART actual process data length, complete date exchange whereby the master sends an instruction telegram and the slave issues responses takes up to 0.5 seconds assuming a transmission speed/baud rate of 1,200 bit/s. For point-to-point configuration, 2 to 3 telegrams can be exchanged.

Actuator controls General information on HART AC(V) 01.2/AC(V)ExC 01.2 HART input resistance of actuator, etc.). The total resistance of the current loop including the cable resistance must amount to minimum 230 Ω and maximum 1,100 Ω . In case the available resistance of the current loop is too low, a so-called communication resistor must be integrated in series.
Address M1253 Information These settings can also be performed via a Bluetooth device (via PC, laptop, ...) and the AUMA CDT service software or the AUMA Assistant App. 2.6. HART communication cable The correct selection of HART communication cable can be crucial. It depends on length, cross section as well as ambient conditions if foreign signals might cause interferences.
