Link Blocks
Modular Block System: Hydraulic Presses
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.
