When your system is based on Siemens PLC as a main controller you can easily extend its I/O support, by using any FLEXBOOL controller as an I/O extender. In this example we will use FLEXBOOL model 3 as an I/O extender of SIEMENS LOGO 8 controller, thus adding 72 protected, and factory calibrated Inputs/Outputs, as well as an integrated UPS battery charger, all monitored and controlled via Modbus TCP.
You can build your program using the Siemens Soft Comfort ladder SW and make user interface by Siemens LWE. The same approach can be used with FLEXBOOL 2 and Lite models.
