Fox20

The Fox-20 module has four sockets for digital and analogue sub-modules (the first socket is for analogue sub-modules only).

Variables

All possible variables are displayed in the tree. The variables can/must be linked depending on what is plugged into the Fox-20 module. If an analogue sub-module has been plugged into a socket, the word variables Modx_Chny in the input and/or output area can be linked. In which x stands for the sub-module socket and y for the channel corresponding to that socket.

In the case of digital sub-modules (one channel only) the bit variables must be linked below the Modx_Chn1 variables.

The links tell the TwinCAT System Manager whether the fiberoptic telegram is for a digital or an analogue sub-module.
