Using HART Analog I/O Signals
Getting Started
Overview
Foundation Application Templates
The Hardware Mapping Editor allows you to map only one signal per channel of a supported HART analog I/O module, which is configured in the topology. The
HART module is acting as a regular I/O module and the signal corresponds to the
Primary Variable (PV). The other HART signals, for example, Secondary Variable
(SV), Tertiary Variable (TV), and/or Quarternary Variable (QV) are not available.
This chapter describes that additional steps that are required to be able to use all
HART signals (including PV) coming from supported HART analog I/O modules by using their device DDT variables. In such case, no more hardware mapping is required for HART input signals. Hardware mapping is still required to send the 4-
20 mA output signal to a HART module.
The manual configuration involves using the Application Explorer and the
Project Explorer of the engineering client.
NOTE: For instructions how to configure HART modules in the topology, refer to the topic describing how to complete the configuration stage (see
EcoStruxure ™ Process Expert, User Guide).
Prerequisites
• One or more HART analog I/O module exists in the Topology Explorer in a controller of the M580 or Quantum platform, which contains a NOC communication module.
• The corresponding HART I/O module device type manager (DTM) is added and configured (except for the configuration of process data, which is described in this procedure). Refer to the corresponding User Guide (see
EcoStruxure ™ Process Expert, Control Participant Services, User Guide).
• The necessary HART device DTMs are installed in EcoStruxure Process
Expert. This is required to be able to configure or monitor HART devices. If the devices are already configured, the installation of device DTMs is not necessary. (Contact vendor to obtain the device DTM if necessary).
Modifying an Existing System
If you are already using a HART analog I/O module in your system and are accessing PV by using an instance of $AnalogInput1 or $AISignal_UL through the hardware mapping, you can access the other HART signals by using the procedure described in this chapter. You do not need to modify the way you have implemented PV. Both methods can coexist in the same system.
