Configuring SIMATIC PDM for HART Routing Through S7-1500 and ET 200SP CPUs

In SIMATIC PDM V9.1 Upd 6, configuring HART field instruments connected to ET 200SP HART analog input modules (6ES7134-6TD00-0CA1) controlled by an S7-1500 Open Controller (CPU 1510SP-1 PN) requires routing through a properly configured PROFINET IO system. Because CPU 1510SP-1 PN is an S7-1500 Software Controller that does not appear in the classical STEP 7 / PDM object catalog as an autonomous PLC rack, the ET 200SP station must be integrated into PDM Process Device Network View using the S7-1500 PROFINET network model or via an ET 200SP Interface Module (IM 155-6 PN) proxy, ensuring that the ET 200SP HART Device Integration Manager (DIM) packages are imported.

Executive Summary

Modern hybrid process automation architectures increasingly combine classical SIMATIC PCS 7 distributed control systems with modular SIMATIC S7-1500 and ET 200SP distributed controllers. When field instruments with HART communication are connected to ET 200SP analog input modules governed by an ET 200SP Open Controller (CPU 1510SP-1 PN), commissioning engineers frequently utilize SIMATIC PDM V9.1 for centralized calibration and diagnostics. However, engineers encounter roadblocks when searching for the CPU 1510SP in the PDM catalog or receive 'Module not supported' diagnostics when substituting standard interface modules. This article clarifies the routing architecture of PDM through S7-1500 controllers, explains catalog prerequisites, and provides a verified parameterization procedure.

Architecture and Fundamental Mechanics

PDM HART Routing Architecture, S7-1500 Dataset Routing, and EDD Device Catalog Integration:

Architecture of PDM Dataset Routing across PROFINET:
SIMATIC PDM communicates with HART instruments over PROFINET using S7 Dataset Routing (Record Data 0x4B00 - 0x4BFF).
The engineering station sends HART request telegrams packaged in S7 records to the controller's IP address.
The controller parses the record and routes it across its internal backplane to the designated ET 200SP HART I/O module.
The HART I/O module modulates the digital FSK telegram onto the 4-20 mA current loop to reach the field sensor.
Catalog Discrepancies between STEP 7 Classic and S7-1500:
SIMATIC PDM V9.1 was originally developed for the classical STEP 7 V5.x environment (S7-400 / S7-300).
S7-1500 controllers—including the ET 200SP Open Controller CPU 1510SP-1 PN—are native TIA Portal devices.
When using PDM within STEP 7 V5.6, the classical hardware catalog does not recognize CPU 1510SP as an S7-400 CPU entity.
If an engineer incorrectly substitutes a standard IM 155-6 PN header, PDM attempts to address the module as a distributed slave rather than an integrated CPU backplane, resulting in Module not supported.
Resolution Architecture:
To route HART data through CPU 1510SP-1 PN in PDM V9.1:
1. Import the latest SIMATIC PDM Device Integration Manager (DIM) catalog update containing the S7-1500 / ET 200SP HART descriptors.
2. In PDM Network View, create a generic PROFINET network, assign the IP address of the CPU 1510SP-1 PN, and insert the ET 200SP station with its specific HART AI modules.
3. Alternatively, utilize SIMATIC PDM standalone with the TIA Portal PDM Integration option.

Step-by-Step Implementation Procedure

Update PDM Device Catalog via Device Integration Manager (DIM):
* Launch Device Integration Manager from the Siemens Automation start menu.
* Select File > Open and browse to the latest SIMATIC PDM Device Library DVD / download source.
* Expand PROFINET > ET 200SP.
* Ensure that the Electronic Device Description (EDD) for AI 4xI 2-wire 4..20mA HART (6ES7134-6TD00-0CA1) is checked.
* Click Install to compile the descriptors into the local PDM database.
Enable HART Diagnostics in Hardware Configuration:
* In your hardware configuration software (TIA Portal or STEP 7), open properties for the ET 200SP AI HART module.
* Under Module Parameters, ensure that HART communication is enabled on active channels.
* Download the hardware configuration to the CPU 1510SP-1 PN.
Configure PDM Process Device Network View:
* In SIMATIC Manager, select View > Process Device Network View.
* Insert a PROFINET network object; configure the subnet IP address range.
* Insert an S7-1500 Station (or generic PROFINET IO device) representing the CPU 1510SP-1 PN with its active IP address.
* Under the station, insert the AI 4xI HART module in its exact physical slot.
Insert Field Instruments Under Module Channels:
* Right-click the channel under the HART AI module and select Insert New Object > Object.
* Select the instrument manufacturer and model (e.g. SITRANS P DS III or Rosemount 3051).
* Configure the HART address (default 0).
Execute Online Parameterization:
* Double-click the field instrument in PDM.
* PDM routes through the CPU 1510SP-1 PN and establishes an online session with the sensor.
* Upload and verify device parameters.

Verification

In SIMATIC PDM, select the field instrument; select Device > Open Object.
Confirm that the status bar turns green and reports 'Device connected'.
Verify that the live process variable (PV), loop current, and instrument serial number update accurately.

Limitations and Operational Precautions

CPU 1510SP-1 PN must have its PROFINET interface firmware updated to a version supporting dataset routing. Older firmware versions (prior to V2.0) may reject PDM record data routing telegrams.

Engineer FAQ

Why is CPU 1510SP-1 PN missing from the classical PDM catalog?

CPU 1510SP is a modern TIA Portal controller; classical STEP 7 / PDM V9.1 catalogs manage S7-1500 devices via generic PROFINET objects or TIA PDM integration.
