Sequential Block Processing

Description of Basic Function

Note: First of all the same basic rules as to single block processing

(see that section) apply to sequential block processing. In

addition to mere positioning block functions with defined

positioning blocks and block acceptance, there also is a

defined block transition to be parameterized.

A positioning block with sequential block is selected and activated in the

usual way, only the first block of the sequential block chain being

selected. The sequential block is the block with the next higher block

number. A sequential block can also have a sequential block so that after

a start block up to 63 sequential blocks can be set.

Note: The potential sequential block of the last valid block is block 0.

There are two basically different modes for block advance that can be

subdivided:

1. Mode: position-dependent block advance

• block transition with old positioning velocity

• block transition with new positioning velocity

• block transition with intermediate stop

2. Mode: switch-signal-dependent block advance

Position-Dependent Block Advance

With position-dependent block advance, switching to the sequential block

is carried out at the target position of the start block.

There are three different types of block transition:

a) Block transition with old positioning velocity (mode 1)

• P-0-4019, Positioning block mode = 11h

→ absolute block with sequential block

• P-0-4019, Positioning block mode = 12h

→ relative block with sequential block

• P-0-4019, Positioning block mode = 14h

→ infinite block in positive direction with sequential block

• P-0-4019, Positioning block mode = 18h

→ infinite block in negative direction with sequential block

In this mode the target position of the start block is run through at the

velocity of the start block. Then the positioning velocity is switched to that

of the sequential block.

With relative and absolute positioning blocks with block advance, the

drive moves in the direction of the target position. As soon as the target

position is passed, the drive switches to the next travel block n+1.

With infinite positioning blocks, the drive moves in positive or negative

direction. As soon as the target position is passed, the drive switches to
