L_PosSequencer - sequence control

This FB processes a positioning program based on a sequence table.

• The sequence table is an important part of this FB and is indicated by a code with 100 subcodes.

Each subcode contains a reference to a single program segment, also known as "action".

• Different action types are available which serve to implement, for instance, program branching,

switching operations, waiting times and counters. The actions themselves are also indicated by

codes.

• The following action types are passive: Branching, variable branching, switching, counter set-

ting, counting, waiting, standby, and program end. When these action types are processed,

the deceleration ramp is active and a brake, if available, will be applied.

• The action types positioning and homing are active since these both action types trigger the

execution of the corresponding basic function via control outputs.

Note!

For a complete sequence control, the FB L_PosSequencer must be connected to further

blocks, like the FB L_PosPositionerTable (profile data record management) and the

SB LS_Positioner (basic function "positioning").
