Communication and Software

Optimize the performance of your plant and enable efficient service

The key to optimizing plant performance and increasing the added value of installed process analytics is digitalization. Therefore, our analyzers offer modern communication interfaces such as Modbus TCP, PROFIBUS etc., which connect to existing plant networks and provide helpful additional data about the health status. Our devices can be configured remotely via appropriate maintenance software. And additional performance tools such as the Analyzer System Manager and SITRANS AID IQ help you to realize the optimal performance of the devices with the help of data analytics.

The operating and monitoring system Analyzer System Manager (ASM)

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

Say hello to the Analyzer System Manager

The customer challenge: Improving Key Performance Indicators (KPIs) and monitoring of process analyzers. 


The solution: The Siemens Analyzer System Manager (ASM)


All information at a glance

Analyzer System Management solution is collecting analyzer data to enable centralized monitoring of analytical systems.  ASM allows the users to validate and calibrate manually, semi-automatically, or automatically all analyzers from a central control room. With the comparison and analysis of validation results and using the process values of dosing units and information of Laboratory Information Management Systems (LIMS), a reliability and quality can be reached. 


Analyzer performance and possible deviations can be monitored and statistically evaluated through individual rule-setting or through usage of ASTM rules.  Through long-term analysis of deviation developments possible maintenance need in future can be recognized and service activities can be planned and optimized. Needed functionalities for maintenance planning and documentations are provided through ASM.


ASM provides Key Performance Indicators (KPIs) of your installed base such as e.g. availability to the analyzers and displays these in customized reports which can be used for internal reporting. Also occurred warnings of analyzers or open and solved maintenance tasks can be shown beside other views.  


ASM integrates analyzers from Siemens and 3rd party products with various communication protocols in Siemens own homogeneous environment. ASM integrates current analyzer measurement data based on standard industrial communication protocols from the analyzer directly, as well as from other Process Control Systems.  The scalable system grows along with the customer requirements as ASM projects are adapted to customer specific requirements. A wide spectrum of analyzers with various communication protocols is integrated on a Simatic controller.

Optimized availability of your Siemens Analyzer using Predictive Maintenance with SITRANS AID IQ

One of the biggest challenges for users of process analyzers is to ensure the optimal availability of any analyzer - either resulting from process requirements or the obligation to fulfill legal requirements. To date, this has only been ensured through reactive service and regular preventive maintenance, leading to a number of challenges: Unplanned downtimes and related challenges (e.g. travel times of external experts, ordering of spare parts) lead to low availability, unnecessary and avoidable costs.

That's why Siemens Measurement Intelligence offers SITRANS Analyzer Intelligence Director IQ (SITRANS AID IQ), a software solution that provides additional support to users of our Siemens process analyzers, while ensuring optimal analyzer availability.

We offer a comprehensive software package with intuitive operation for communication and control of Siemens analyzers, such as MAXUM Ed. II and GA 700.

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, ULTRAMAT 23 and SIPROCESS GA700 gas analyzers can all be configured and monitored with this software. SIMATIC PDM can also 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 Advance Maxum, Maxum edition II and MicroSAM gas chromatographs connected to Ethernet. This intuitive software allows access to, for example, device status, analytical results, parameters and chromatograms. 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 and MicroSAM gas chromatographs connected to Ethernet, and makes this data available to higher-level systems, for example 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. It is based on a master/slave or client/server architecture, 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, SITRANS SL and SIPROCESS GA700


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 und MicroSam 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/MicroSam, 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.
