Safety Output Configuration - Mitsubishi Electric MELFA CR800 Series Instruction Manual

4 SAFETY MONITORING FUNCTIONS

Safety output configuration

4.4.2
This enables assigning the Enable and Disable states of the safety monitoring states (STO, SOS, SS1, SS2, SLS*,
SLP*) and Area states to DSO1 to DSO4 of the safety extension unit.
The configuration is used for displaying safety monitoring states or connecting other safety devices.
Fig. 4-29: Safety output configuration
The matrix in the Safety Output screen has rows representing the safety outputs (DSO1 to DSO4), safety
monitoring states (SS1, SS2, SLS1, SLS2, SLS3, SLSM, SLP1, SLP2, SLP3, SLPM) for the safety functions, and
Area Input (AREA1 to AREA3). The columns represent target safety functions and Area Inputs.
Checking intersections of the rows and columns defines safety signals output when the individual safety
monitoring states and Area Inputs become Enable or Disable.
Example 1) To turn on DSO2 when SOS is enabled, check the intersection of DSO2 and SOS (at Enable).

LOGIC enables the AND and OR conditions of Enable and Disable of multiple safety monitoring states to control
turning on or off the DSO_ signals.
