Selecting and Deploying SIMATIC PDM for Third-Party HART Field Device Configuration

Selecting and Deploying SIMATIC PDM for Third-Party HART Field Device Configuration

In SIMATIC PCS 7, configuring intelligent third-party HART field instruments—such as the Rosemount 3051 Pressure Transmitter or Rosemount 8732E Magnetic Flowmeter—requires SIMATIC PDM (Process Device Manager) paired with the appropriate Electronic Device Description (EDD) files. SIMATIC PDM operates either as an integrated component within SIMATIC Manager (enabling HART routing across the Industrial Ethernet Plant Bus and remote I/O backplanes) or as a standalone service tool on an engineering laptop with a HART modem. To integrate third-party transmitters, install the current SIMATIC PDM software release (such as V9.1 or V9.2), import manufacturer-specific EDD files using the Device Integration Manager (DIM), and assign the device in HW Config or the PDM Network View.

Executive Summary

Intelligent field instrumentation in process manufacturing plants relies heavily on the highway addressable remote transducer (HART) communication protocol for sensor calibration, range configuration, diagnostics, and NAMUR NE107 maintenance alerts. In Siemens PCS 7 plants, instrument engineers utilize SIMATIC PDM as the universal engineering tool to manage thousands of multi-vendor devices. When deploying non-Siemens transmitters (such as Emerson Rosemount 3051 or 8732E devices), engineers frequently require guidance on software selection, device description (EDD) catalogs, routing prerequisites, and licensing structures. Understanding PDM software architecture guarantees seamless instrument commissioning from the central engineering console.

Architecture and Fundamental Mechanics

The device description, communication routing, and software architecture of SIMATIC PDM operate through distinct framework components:

  1. The Electronic Device Description (EDD) Framework:
    * Unlike standard fieldbus slaves that use static GSD files for cyclic I/O data sizing, intelligent HART instruments utilize Electronic Device Description (EDD) files.
    * The EDD acts as a software driver that interprets internal vendor menus, sensor calibration trim routines, damping factors, and diagnostic registers.
    * Siemens bundles thousands of pre-tested device descriptions in the SIMATIC PDM Device Library, while vendor-specific EDD packages (e.g., Emerson Rosemount) can be imported independently.
  2. The Device Integration Manager (DIM):
    * EDD files cannot simply be pasted into Windows directories.
    * The Device Integration Manager (DIM) utility compiles, validates, and registers device descriptions into the central PDM device catalog database.
  3. HART Communication Routing Across PCS 7:
    * In integrated PCS 7 environments, PDM does not require physical wiring connections to the field instrument.
    * Using HART Routing, SIMATIC PDM communicates from the Engineering Station over Industrial Ethernet to the S7-400 / CPU 410 controller, traverses the PROFIBUS DP or PROFINET network to the distributed I/O station (ET 200M, ET 200SP, or ET 200SP HA), and passes through the HART-enabled analog module directly to the field transmitter.
  4. SIMATIC PDM Licensing Structure:
    * PDM licensing scales based on the number of configured field devices (TAGs):
    • SIMATIC PDM Basic: Provides entry-level standalone configuration (typically 4 TAGs).
    • SIMATIC PDM Integration in STEP 7 / PCS 7: Enables integration into SIMATIC Manager.
    • SIMATIC PDM TAG Expansion Packages: Available in increments of 100, 1,000, or 10,000 TAGs.

Step-by-Step Implementation Procedure

Follow these procedures to install, integrate, and configure third-party HART instruments in SIMATIC PDM:

  1. Procure and Install SIMATIC PDM Software:
    * Obtain the appropriate SIMATIC PDM release matching your PCS 7 environment (e.g., SIMATIC PDM V9.1 for PCS 7 V9.1).
    * Close all SIMATIC Manager applications and execute Setup.exe with administrative rights.
    * Select the integration option SIMATIC PDM in STEP 7 / PCS 7.
  2. Import Device Descriptions via Device Integration Manager (DIM):
    * Open Windows Start Menu and launch Siemens Automation > SIMATIC > PDM > Device Integration Manager.
    * Click Source > Browse and select the Siemens Device Library or manufacturer EDD folder containing the Rosemount 3051 / 8732E files.
    * In the device list, locate Pressure > Gauge Pressure > Rosemount > 3051.
    * Check the device and click Integrate.
    * Verify that the DIM status log reports successful integration without schema errors.
  3. Configure HART Analog Input Module in HW Config:
    * Open HW Config in your PCS 7 project.
    * Ensure the distributed I/O station features a HART-capable analog input module (e.g., SM 331 8x12Bit HART or ET 200SP HA AI 8xI 2-/4-Wire HART).
    * Double-click the module, open the HART tab, and verify that HART protocol is enabled on the target channel.
  4. Assign Field Device in HW Config or Process Device Plant View:
    * In HW Config, right-click the specific channel of the HART module and select Insert HART Device.
    * In the PDM catalog dialog, select Rosemount > 3051 and click Assign.
    * Alternatively, configure devices in SIMATIC Manager under the Process Device Plant View.
  5. Open PDM and Execute Online Commissioning:
    * Right-click the configured device in HW Config and select Start SIMATIC PDM.
    * PDM establishes a routed connection to the physical transmitter.
    * Execute parameter read: Device > Upload to PG/PC.
    * Adjust parameters (e.g., Lower Range Value, Upper Range Value, Damping Time) and download to the transmitter via Device > Download to Device.

Verification

In SIMATIC PDM, open the online dialog: View > Process Variables. Verify that the live primary variable (PV - Pressure), secondary variable (SV - Sensor Temperature), and analog loop current (4..20 mA) match field values. Open Diagnostics > Device Status; confirm that the device indicates 'Good' status without internal sensor faults or electronic errors.

Limitations and Operational Precautions

Ensure that distributed I/O interface modules and controllers support HART routing (e.g., standard IM 153-2 or IM 155-6 PN); non-HART modules cannot pass FSK frequency signals. Device TAG licenses must be adequately sized in Automation License Manager to prevent license overrun warnings.

Engineer FAQ

Can SIMATIC PDM configure third-party devices from vendors like Rosemount or Endress+Hauser?

Yes. SIMATIC PDM is an open, vendor-neutral tool that supports any field instrument providing an approved EDD or FDI device description.

What is the difference between SIMATIC PDM Standalone and Integrated?

Standalone operates as an independent desktop tool connecting via a local HART modem; Integrated embeds within SIMATIC Manager and utilizes network HART routing.

What tool is used to import new EDD files into PDM?

The Device Integration Manager (DIM) is used to import, compile, and register EDD packages into the PDM catalog.

Do HART channel drivers (Pcs7AnIn) require PDM to operate?

No. Standard analog measurements run without PDM; PDM is only required for deep parameter configuration, calibration, and extended diagnostics.
