Analyzer System Manager (ASM)

Siemens offers reliable products across the entire analytics portfolio, from analyzers to interfaces and software. A highlight is our Analyzer System Manager (ASM), a software tool capable of monitoring analysis systems, optimizing device performance, measuring value quality, maintenance planning and even reporting the most important KPIs.

Communication and Software

Automated monitoring and validation of your analytical devices

Our analyzers have standardized fieldbus communication interfaces, such as Modbus and Profibus. We provide coordinated software tools for commissioning, diagnosis and remote access. The Analyzer System Manager (ASM) is a monitoring system that helps improve device performance, lets you visualize device performance, evaluate plant KPIs, and establish the basis for predictive maintenance.

Process Analyzer Management


Monitor, visualize and validate for better performance and reliability. Analyzer System Monitoring and Management ensure the quality of analytical measurement used in permit compliance, product quality, process control, safety and other applications. Siemens offers Analyzer System Manager (ASM) with increasing levels of functionality.



Analyzer System Manager (ASM)

Operating and monitoring system

The Analyzer System Manager is a PC system for monitoring, management and optimization of gas analyzers. The relevant information from different analyzers is collected via various communication protocols and saved in a central database. The user-friendly operator interface makes it possible to access measured value trends, device states and statistical evaluations, or to start test routines for validation. The collected information can be used to analyze long-term performance of your installed base in order to optimize service requirements through predictive maintenance. A comprehensive reporting module with predefined reports is available to document the evaluations. 

Information at a glance

Analyzer System Management is a centralized solution for collecting and monitoring analytical system data. ASM allows users to validate and calibrate all analyzers manually, semi-automatically or automatically from a central control room. HIgh reliabilty and quality can be maintained through comparison and analysis of validation results, combined with information from Laboratory Information Management Systems (LIMS).


Analyzer performance can be monitored and deviations statistically evaluated through individual rule-setting or through usage of ASTM rules. Predictive maintenance can be optimized through long-term analysis and documentation of performance provided through ASM.


ASM provides Key Performance Indicators (KPIs) of your installed base, such as availability to the analyzers, and displays these in customized reports that can be used for internal reporting. In addition, analyzer warnings or open and solved maintenance tasks can be viewed.  


ASM integrates analyzers from Siemens and third-party products with various communication protocols in one integrated environment. The scalable system grows along with the customer requirements as ASM projects are adapted to specification. A wide spectrum of analyzers with various communication protocols is integrated on a SIMATIC controller.

We offer a comprehensive software package with intuitive operation for communication and control of Siemens analyzers, such as MAXUM process gas chromatograph and any networkable analyzer.

Continuous process gas analytics, extractive

    SIPROM GA is a free software program for communication between your PC or laptop and Series 6 or ULTRAMAT 23 analyzers. It is used for parameter assignment, maintenance and diagnostics. SIPROM GA accesses analyzers either directly from your PC or via an RS 485 port or Ethernet gateway
    SIMATIC PDM (Process Device Manager) is a universal, vendor-neutral tool for the configuration, parameter assignment, commissioning, diagnostics and maintenance of intelligent field devices. Series 6 and ULTRAMAT 23 gas analyzers can also be configured and monitored. SIMATIC PDM can be integrated into the SIMATIC PCS 7/STEP 7 configuration environment to monitor the entire plant. The PC and analyzers can communicate via Ethernet and Profibus.

Continuous process gas analytics, in-situ

  • LDSComm
    For service and maintenance purposes, LDS 6 and SITRANS SL can send and receive data over an Ethernet connection. This service and maintenance tool can check and adapt the device status and calibration parameters from a remote location. If required, a complete system check can even be conducted remotely. If servicing is required, the necessary information can be sent by modem to Siemens service staff, who will then carry out the necessary measures remotely. This remote maintenance and diagnostics function is realized with a standard LAN modem.

Process gas chromatography

  • Gas Chromatograph Portal
    The Gas Chromatograph Portal workstation software, an upgrade of the System Manager and EZChrom software, enables simple monitoring and parameter assignment of Maxum edition II gas chromatographs connected to Ethernet. This intuitive software allows access to device status, analytical results, parameters and chromatograms, among others. The Gas Chromatograph Portal workstation software also includes tools for data logging, reporting and network monitoring of connected devices.
  • MAXUM OPC Server
    The MAXUM OPC Server software tool collects measured values, device status, analytical results, etc. from Maxum edition II gas chromatographs connected to Ethernet, and makes this data available to higher-level systems, e.g. the process control system, via an OPC DA server.

The reliable operation of analysis devices is crucial to process management. Measured values must be collected, corrected, and transmitted for this purpose. Siemens offers different communication capabilities, such as Modbus and Profibus, which can be selected according to your needs


The Modbus protocol is one of the longest-established transmission standards on the market for industrial communication. Based on a master/slave or client/server architecture, it is effective and easy to implement.

Modbus is a communications protocol for data transfer. In the petrochemical industry, Modbus is widely used for connecting measuring and control devices to process control systems (PLCs). Most PLCs can be fitted with interfaces for Modbus communication. Modbus interfacing enables the reliable transmission of information over just one data line. It can be used both to read information from analyzers and to control certain functions. A distinction is drawn between Modbus RTU, Modbus ASCII (both based on serial field bus communication) and Modbus TCP (Ethernet-based).


Modbus is supported by MAXUM edition II and SITRANS SL.


PROFIBUS (Process Field Bus) is a standard for fieldbus communication. The two main versions are:

  • PROFIBUS DP (distributed I/O), designed for the efficient exchange of data at the field level. This is where the central automation devices such as the PLC/PC communicate with distributed field devices over a high-speed serial connection. Data exchange with the distributed devices is primarily cyclical.
  • PROFIBUS PA (Process Automation) is used for communication between measuring and process devices, actuators and process control systems or PLC/DCS in process engineering. PROFIBUS PA is not a separate bus: it is a version of PROFIBUS with a physical layer designed for process automation (transmission layer). PROFIBUS PA is also suitable for hazardous atmospheres thanks to power limitation.

PROFIBUS PA is supported by Series 6 gas analyzers and ULTRAMAT 23. 

PROFIBUS DP is supported by Series 6 gas analyzers, ULTRAMAT 23, and SITRANS SL. 


The OPC DA specification defines the exchange of data such as values, time and quality information. OPC has a typical client/server architecture. Standard OPC DA (Data Access) is available for Maxum edition II data transfer.

NAU - Network Access Unit

The Network Access Unit (NAU) is an input/output station for Siemens process chromatographs. It can be used to centrally access, process and relay data. The NAU is used if the electronics system cannot be connected close to the analyzers, there are not enough inputs/outputs in the Maxum edition II, or installation in a central control room is required. This significantly reduces the wiring required to the control room. The data can also be provided via Modbus.
