![]() ![]() When the input goes high, Accum is set back to 0. Timer-Off-Relay (TOF) – This timer works just like the TON timer except that it starts when the input goes low.This will happen regardless of whether Accum has reached Preset or whether counting is still under way. When the NO input goes low, Accum is set back to 0. ![]() When Accum reaches Preset, DN is set high. Timer-On-Delay (TON) – The timer clock starts counting seconds in Accum when the NO input is set high.The timer can be configured to work in three different ways. It is similar to the counter in that there is an Accum variable to count the seconds that have passed and a Preset variable, which is a preset span of time to be reached before some other process can begin. PSIM PLC SIMULATOR PATCHIf binaries are not available for your host, then you will need to patch GDB to include the latest patch in contrib/crossrpms/patches in the RTEMS CVS checkout.The timer marks time. PSIM PLC SIMULATOR INSTALLThe simplest way to get started with PSIM is just to install pre-built GDB binaries for your host environment. In addition to describing that release of PSIM, this document also describes extensions that have been proposed for a future release of the PSIM Architecture The most recent formal release of PSIM is version 2.1. This detailed performance monitoring (unlike many other simulators) resulting in only a relatively marginal reduction in the simulators performance. In addition, PSIM, to the execution unit level, models the performance of most of the current PowerPC implementations (contributed by Michael Meissner).
