5.3.2 Shared virtual inputs and outputs
It is possible to share Binary and Analog values between all the controllers via CAN bus, thus saving physical
Inputs and Outputs and excess wiring.
How to add a virtual module is shown in the following picture.
The principal of how shared Binary inputs and Binary outputs work is shown below.
Shared Binary Inputs and Outputs may be used exactly in the same way as standard physical Inputs and
Outputs. If SHBIN or SHAIN modules are configured, at least one corresponding module of SHBOUT or
SHAOUT (respectively) is needed. If it is not configured, corresponding protection appears because SHBIN or
SHAIN will be missing. See the figure below for more information.
IMPORTANT: For proper function of Shared Binary and Analog Inputs and Outputs, only one
source of Shared Binary or Analog Outputs must be configured (i.e. it is not possible to configure
in one controller SHBOUT1 and to another one as well SHBOUT1).
