Changing Revolution Pi projects or the runtime system for Revolution Pi to use the generic IO provider
The access to hardware IOs of a →Revolution Pi is possible by using a generic IO provider concept of Neuron Power Engineer. This article informs whether and which steps are necessary for this access.
Recommended: Using the project template "Counter Project for Revolution Pi" in Neuron Power Engineer version ≥ 1.120.0 and Neuron RTS max version ≥ 3.31.0
You do not have to do anything. Reasons:
-
The PLC-object
RevolutionPi
of the Revolution Pi project that has been created based on the project template Counter Project for Revolution Pi in Neuron Power Engineer version ≥ 1.120.0 already contains the needed code. -
Neuron RTS max for Revolution Pi, ≥ version 3.31.0 is already correctly configured.
Using other projects
If you want to use other projects (e.g. projects that have been created by using a Neuron Power Engineer version 1.119.0), the following specification for IO_IMPORT
is required within the PLC-object:

Using Neuron RTS max configuration file from a previous Neuron RTS max version
It is indispensable to use Neuron RTS max for Revolution Pi, ≥ version 3.31.0! |
If you want to go on using the Neuron RTS max configuration file of a previous Neuron RTS max version, you have to change this file.
-
If Neuron RTS max is running, terminate Neuron RTS max.
-
Copy the configuration file
/opt/RTS/PLC/RTSIO.cfg
of the previous Neuron RTS max version into the installation directory of the current Neuron RTS max version. -
Open the file
/opt/RTS/PLC/RTSIO.cfg
in a text editor. -
Search for the following lines:
