Link Blocks

Modular Block System: Emergency Stop Circuits

These can be optimised during commissioning.

- Enter a minimum scan time.

- If test pulses are to be connected to the 3 ms inputs (E x.16 ... E x.31):

Make sure the DI test time is set correctly.

• Establish the sequence in which the blocks will be called up

- MBS blocks must be run through as part of each cycle.

- Aid: Flow chart and listing.

• Create a supervisory (master) block

- The master block should be either a PB or an FB

(if parameters are required: FB).

- Call up the blocks in the correct sequence and set parameters for them

° Assign a different number to each block SSNR (1 ... 600)

° Document the SSNR you have used

° If necessary, combine the enable output parameters (FG/ENBL) into

suitable groups by means of a logic AND-operation.

- Remember to take into account any links which have already been

made.

- Enter details on the operation of the selected fault indicator

• Import / set up DB015 or DB015/DB016/DB017 in the project

- DB015/DB016/DB017 must always contain 1024 data words

- DB015/DB016/DB017 must have READ/WRITE status

• Create OB120

If necessary, add SB070 or SB071 call.
