At the heart of the 353 is a powerful MPU Controller board that uses the latest in microprocessor technology. It
includes on-board I/O and reusable function blocks, and it is capable of solving a vast array of control
implementations including single loop, cascade, and dual loop. Available MPU board I/O is listed in the table
below.
Modbus and Modbus/TCP Ethernet are standard networking communication options that are used to connect
multiple controllers to an operator workstation, Human/Machine Interface (HMI), or DCS, enabling integration of
controllers into a plant-wide system. A popular HMI is the Procidia™ i|station™ running i|ware PC™ operator
interface software. A communication port (RS232) on the underside of the Display Assembly is available for
configuration and/or debugging when using i|config™, the optional PC-based Graphical Configuration Utility.
An optional I/O Expander Board can be added to the base Siemens 353. It includes direct thermocouple, RTD, and
frequency inputs and additional I/O for direct process measurement of temperature and frequency variables,
improving accuracy and control. Available Expander board I/O is listed below.
