As an automation specialist, you like to buy everything from a single source. But what do you do if the required products from the preferred manufacturer are not available on the announced date? Now at the latest it is time to look at alternatives.
The PROFINET Remote I/O of the PFN-2000 series are ideally suited for PROFINET I/O applications in which, for example, a SIEMENS S7 or compatible PLC acts as the central control unit and in which further analog and digital signals have to be processed decentrally.
The I/O modules correspond to Conformance Class B and RT Class 1 and are therefore particularly suitable for applications with cycle times in the >1ms range. The integrated switch with two Ethernet ports enables flexible cabling in different topologies. The I/O signals are conveniently applied via push-in terminals and the module is simply mounted on the DIN rail. The large input voltage range of 10-30VDC also copes well with wavy control cabinet voltage.
The I/O offer ranges from the universal 8DI/8DO module to 10AI with individual channel configuration for mV, V, mA or T/C type J/K/T/etc. up to 4AO with 0-10V or 0/4-20mA output. The software integration of the PFN-2000 modules into the PROFINET project takes place as usual by importing the associated and supplied GSDML file into the engineering tool.
The advantage of using a widespread and standardized technology such as PROFINET lies in the independence from individual brands or manufacturers.
