5.9 Connecting binary outputs
Option DCS..B offers a total of 6 binary outputs. The 3 binary outputs DO0_P, DO1_P
and DO2_P are positive switching, the 3 binary outputs DO0_M, DO1_M and DO2_M
are negative switching.
Depending on the required performance level, you can use binary outputs individually
or combined in groups.
If the unit-internal diagnostic function is enabled, it will cyclically check the binary outputs
for proper functioning. During this plausibility check, the binary output is switched to its
inverse value for the duration of the check (< 500 μs). This means a P binary output is
briefly switched to DC 0 V potential, and an M binary output is briefly switched to
DC 24 V potential. If an error is detected, the DCS..B option switches to alarm/error
state and indicates this state (see chapter "Diagnostics").
INFORMATION
The following sample circuits assume that the switching elements are configured in
accordance with the required performance level to EN ISO 13849-1 and that safety
approval has been granted for the application in question.

INFORMATION
The binary outputs of option DCS..B must not be connected to fast touch probe inputs
because the diagnostic function might lead to unintentional switching operations.
These are, for example, binary inputs DI00 (X13:1, fixed assignment with "/Controller
inhibit"), DI02 (X13:3) and DI03 (X13:4) of MOVIDRIVE
