This update fixes minor common errors and critical errors in network functions!
- Fixed an issue with all RevPiNetIO classes that prevented a reconnect under certain circumstances.
- Bug fix when using
- Error correction in export file for replaced IOs
- Error correction, setting delayed events to
.core.ios, such as.
- Warnings are issued once when errors occur and after the errors have been eliminated. No more warning floods in the console!
- Error counter on process image improved.
- The function
.reg_event(...) accepts parameter
prefire=True and will execute this event immediately on entering the
- All RevPiNetIO classes require RevPiPyLoad version at least 0.8.0!
- RevPiNetIO classes have the attribute
.reconnecting, which can be used to query whether the connection has been torn down temporarily.
- All RevPiNetIO connections are disconnected when changing piCtory or replace_ios.conf. The attribute
.config_changed will be
True and a new instantiation is needed.
- IOs exported with
.replace_io(...) can be exported to a file and used by other instances or RevPiPyLoad / Control with
replace_io_file for RevPiModIO introduced, for the import of the exported file. With RevPiNetIO
:network: can be used to import this data via RevPiPyLoad over the network.
- Added parameter
direct_output at instantiation [Doc].
- Indexed access to IOs via
.device possible (
This version mainly fixes errors in counter IOs
- Counter IOs 8 – 16 can now also be reset with
- Runtime warnings have better error hints
debug argument introduced to get complete error messages
- Format check implemented by
.replace_io(...) for specific types
Thanks to Nicolai Buchwitz
- Improved argument checking on instantiation
This update introduces the counter-reset of DI / DIO modules!
- Counter IOs now have the function
.reset() to reset the counters on the DI / DIO modules.
Note: The Wheezy (7) system does not support this in the piControl!
- Counter can also be reset via RevPiNetIO over the network (RevPiPyLoad at least version 0.7.5).
- Iterators now issue Python-conforming exceptions.
- The function
.replace_io(...) was offered for all IO objects, but can only be used with gateway or virtual devices. It is now only available on IOs that support this feature.
.mainloop(...) now accepts the
no_warn=True parameter to disable runtime warnings.
At RevPiDay 2018, we introduced you to our RevPiPyLoad extension, which allows us to use NodeRed on the Revolution Pi very easily thanks to MQTT. Here we show you how it works. Continue reading “NodeRed with MQTT in the Revolution Pi”
We would like to introduce you a solution to use events and also do your own cyclical tasks at the same time. Continue reading “Events and own cyclical tasks”
Important update + RevPi Connect
- Core LEDs will not be switched off after instantiation.
- For next generation of virtual devices we now can create more than 16 BIT IOs per memory unit.
- You can control the LEDs on the Cores (next to
.core.a1green.value = True/False /
.core.a1red.value = True/False. These are IO objects that also offer all other functions of the IOs.
- RevPi Connect is supported now!
.core.a3red are available.
- You can control the watchdog with
.core.wd.value = True/False.
- To toggle the watchdog automatically during the program runtime, you can set
.core.wdautotoggle = True.
- Internal IOs of X2
.core.x2out are RevPiModIO.io objects than offer all their features and functions. For example, you can register an event to the internal input of X2
.core.x2in.reg_event(funktion). To set the internal output of X2 use
.core.x2out.value = True.
- For cyclic work after
.mainloop(blocking=False) you can use the new exit signal
while not instance.exitsignal.wait(0.5): to exit your own loop.
The signal is set when invoking
instance.exit() or end of program when using
- Small performance improvements.
READ before UPGRADE!!!
The new version uses a new format of the configuration file ! You MUST install ne new file and migrate your settings! Continue reading “RevPiPyPLC (RevPiPyLoad update to 0.6.5)”
