3.3 Programming
3.3.1 Module Call
The KETTE200 cascade management module (also referred to as func-
tion module) is called only once per PLC cycle in the BTSMADAP function
module, and then services all defined cascade sequences. For this pur-
pose, the number of cascades (i.e., the number of the last cascade se-
quence to be processed) is transferred to the BTSMADAP function
module as a parameter value. The operating modes are directly written
into the respective data modules. In order to be able to form functional
groups of cascade sequences, it is possible to leave strategic gaps when
creating the cascade data modules. Those cascade sequences for which
no data module was defined will then be skipped, and processing will
continue with the subsequent cascade sequence. In order to exclude step
modules from processing, the operating mode for D6 must be described
as 0
hex
, in which case the message returned by the module in D0 of the
cascade data module will be 8000
hex
.
The BTSMADAP.PBL module is called in the OM1 operating module.
BTSMADAP is created with the inclusion of a parameter file which greatly
facilitates calling it during the programming/configuration phase. In the
event that the Call Parameter function is used during programming, the
following program part will appear without requiring additional input:
CM -BTSMADAP,2

P0 B -Kett_Anz ;< ! Number = No. of last cascade
P1 B -K200 ;< ! KETTE200 module no. as constr.
