Offline programming is made with the programming unit but without a
connection to the CL300. The sequence is as follows:
Program generation
D
Storage on a floppy disk
D
Documentation
D
Program transfer to an EPROM memory module (in preparation)
D
which is plugged into the programming unit slot provided for that
purpose
Insertion of the loaded EPROM into the central processing unit
D
In symbol tables, symbolic names are assigned to the absolute ad
dresses of inputs, outputs, markers, timers, counters, organizational
modules, program modules, data modules, and data constants. The
symbolic names may comprise up to 8 alphanumeric characters. For
each symbol, an additional symbol annotation of up to 40 characters can
also be defined.
The cross−reference list specifies the module and the instruction line
where a given operand has been programmed. This output may either
be a sorted sequence of absolute addresses (numeric) or of symbol
names (alphabetic). Another sorting criterion is the command type used.
The module list can also be sorted and output according to module
types.
The instruction list is a list of instructions written in mnemonic form.
The IL is subdivided into program branches. Following each terminating
operation (=, S, R, ...), a new branch is opened. Each branch can have
any number of texts allocated to it. The control instructions are arranged
vertically. Each instruction can have a line annotation in the IL, beginning
with ;".
