F-DI (channel 2.6) : Agreement button
Signal status channel 2 = "1" and channel 6 = "0"
Agreement button not pressed
Signal status channel 2 = "0" and channel 6 = "1"
Agreement button pressed
F-DI (channel 3,7) : <drive on> key
Signal status channel 3 = "0" and channel 7 = "0"
<drive on> key not pressed
Signal status channel 3 = "1" and channel 7 = "1"
<drive on> key pressed
VS1: Internal encoder supply for channels 0 to 3
VS2: Internal encoder supply for channels 4 to 7
Both of these encoder supplies must be used when the short-circuit test is
activated (cf. Chapter "Configuration and wiring of the ET200S I/Os ->
Components of the node IM151 HF: F-DI module).
The exclusive OR sensor agreement button is an exception. For this type of
wiring, the encoder supply VS1 must be used, in conjunction with the short-
circuit test, for both contacts.
The actuators that must be shut down in a safety-related fashion, are
connected through two channels. Shutdown is possible separately for each
channel.
Two valve units are connected in the sample configuration to control the motion
of supplementary pneumatic axes.
