4.5 Step Module
For each cascade, a step module named -SCHRKn (1 ≤ n ≤ 60) is cre-
ated.
The step module contains the following for all controller types:
• the jump distributor to the active step, and
• a maximum of 128 steps.
The processing of the step module always begins with the line of the jump
distributor belonging to the active step. From here, the jump to the actual
step conditions takes place. Only the active step is processed.
As a rule, the step consists of two independent program parts:
• the manual part with the manual conditions, and
• the automatic part with the conditions for automatic and inching
conditions.
Both parts must be separately and independently concluded with the EM
end module instruction.
In the event that the same conditions exist for the manual and automatic
part, only one branch needs to be programmed.
Both the manual and the automatic part are again separated into:
• a command output (BEFA) branch, and
• step-on condition (WSB) branch.
Any number of BEFA and WSB branches can be programmed within a
given step.
In the process of diagnosing sequencing faults, the first non-satisfied
BEFA branch subsequent to the beginning of the step is indicated. If all
BEFA branches are satisfied, the first non-satisfied WSB branch is indi-
cated.
Basic Precepts
♦ Only unconditional jumps may be programmed in the jump distribu-
tor. The jump sequence must correspond to the sequence of jump
destinations.
♦ Prior to the jump distributor, other instructions are not permitted.
The first instruction of the jump distributor must be JP [A].
♦ The jump distributor may not be interrupted by extraneous instruc-
tions.
