Overview
The life science industries have changed the structure on how they validate BAC
systems. Today, the well established risk-based approach leads customers to install a
stand-alone system to monitor all critical parameters, in addition to the BACS system.
The CMT solution is an environmental monitoring system designed to monitor just such
critical parameters.
The CMT is built using the Siemens Desigo building automation and control with the
Desigo PX automation station as the DDC system at the automation level.
The CMT control panel accommodates the DDC system which comprises the
programmed automation station and a range of I/O modules. The I/O modules connect
the installed components (sensors) to the automation station.
The application program in the automation station is used for the following:
 Monitoring of the connected field devices for sensor open circuit or short
circuit, broken connections, I/O modules and signals
 Process alarm monitoring and alarm signals
 Distribution and forwarding of errors and alarms to the management level,
alarm lamp, warning lamp, and alarm to external via potential free switches
 Control of the 2 binary outputs by using a manual software switch (Auto, Off,
On). In the operating state “Auto” the value of an associated time schedule
(connected to the calendar) is used.
 Logging of trend data for the monitored channels and transfer of this data to
the management level for permanent archiving
The I/O modules are modular in design and therefore able to accommodate a wide
variety of signal types. Signal and fault states for analog or digital input/output signals
are displayed by means of LED indicators directly on the module.
Furthermore, the system comprises Desigo Insight and the InfoCenter Suite® at the
management level. These are used for alarm handling, alarm routing, data logging,
reporting, and as a user interface for the visualization of the measured values, which
are displayed on different graphics pages.
The CMT provides free Ethernet ports on the pre-installed Ethernet switch to connect
the system to the customer network. Communications between the automation and
management levels is based on standard Ethernet communications. The system itself
consists of:
• Desigo PXC automation station with TX-I/O modules
• Desigo Insight
• InfoCenter Suite®
The installed and preconfigured operating system and Siemens software allow
connection via Remote Desktop or using Internet Explorer for monitoring and operation.
