The PAC Machine Edition (PME) 10.6 is an integrated development environment software used to configure and manage control system devices, including PACSystems PLCs and QuickPanel HMIs. The addition of PACSystems Simulator enables users to write, test and troubleshoot control logic on a PLC emulator. An all-new data monitor component empowers developers to quickly diagnose and resolve logic issues using plotted data, whether the data is sourced from a physical PLC or the simulator. New OPC-UA PAC server and Profinet enhancements accelerate PLC communication performance, with double the tag count capacity, faster startup speeds and improved processing efficiency. Enhanced user-defined types (UDTs) now propagate data element descriptions across all application instances.
