"4" can be used for example as signal contact for the state evaluation of the E-
STOP button via a PLC.
Only 24 V (protective extra-low voltage) may only be connected to
the E-STOP button!

10.6.8 Sercos III Interfaces
General information
The IndraControl VAM 15.1/VAM 21.1 devices are connected to the field bus via
the X7E1 and X7E2 connectors. The pin assignment of the RJ45 sockets is de-
scribed in
chapter 9.4 "X7E1, X7E2: Sercos III interfaces" on page 14
.
10.6.9 Digital 24 V inputs and outputs
General information
The IndraControl VAM 15.1/VAM 21.1 component group provides 16 digital 24 V
inputs and 16 digital 24 V outputs. The plugs of the inputs and outputs are loca-
ted on the logic circuit board. Green LEDs indicate the I/O states.
The input states are sent to the master control via field bus. The outputs are de-
fined by the master control via field bus.
The pin assignment is described in
chapter 9.5 "X2I1, X2I2, X2O1, X2O2: Digital
24 V inputs and outputs" on page 15
