Integration of existing PT-I/O modules in Desigo Used with PXC50...D, PXC100...D or PXC200...D The PXX-PBUS extension module allows for integrating existing PT-I/O modules in Desigo. The PXX-PBUS extension module, when combined with a PXC50...D / PXC100...D / PXC200...D automation station and TXS1.12F10 supply module, replaces the UNIGYR and VISONIK process units as well as the PXC64-U, PXC128-U automation stations. • PT-I/O modules can continue to be used. • Existing periphery can be assumed without a change. • Control panel wiring can be assumed and need only be supplemented by new supply modules. See installation manual PT modules, M8102. Type summary Building Technologies

Function Existing module carriers with PT-I/O modules can be connected to the PXX-PBUS extension module. All PT-I/O-Module are supported: PTM1... , PTM6.1PSI20-M, PTK1.23V02, PTK1.30V01, PTM50... , PTM52... , PTE-ASED.20, PTE-SED2 (see also PX Hardware overview N9202). The device serves as P-bus interface for modular automation stations PXC50...D, PXC100...D or PXC200...D in Desigo. The PT-I/O modules must now be supplied via the TXS1.12F10 supply module. In current installations, module supply was integrated in the UNIGYR/VISONIK process units or the PXC64-U / PXC128-U automation stations....
