5-5 Modular Block System: Emergency Stop Circuits
Blocks contained in the administration data blocks
Each standard function block occupies 1 data word per block (see
Fig. 5-2). This means a max. of 200 safety devices (e.g. E-STOP 1, E-
STOP 2, safety gate 1) can be managed per administration data block.
The PSS uses a standard function block’s SSNR to automatically generate
the corresponding data words (see section entitled “Input parameter
SSNR”).
