The tabel below shows the current PLC interface options.
As mentioned above, the PLC Interfaces all work in a similar, if not identical,
fashion (the -PL5, -SL5, -ID1, -MFX, and -SQD interfaces are more unique
than any of the others - refer to the PLC SPECIFIC sections for detailed
information on how to use these interfaces).
Initialization of the PLC Interface (setting the proper communication
parameters and verifying the establishment of the link between the PLC and
the T-60 or T-61) always occurs with the CALL PLCINIT command. This
command need only be issued once, usually during the initialization portion
of your program. Any data that you wish to get from the PLC is retrieved by
the CALL PLCREAD command. Data that you wish to write in a register,
memory locations that you wish to define, or I/O bits you wish to set are all
effected with the CALL PLCWRITE statement.
The following section describes the CALL PLCINIT, CALL PLCREAD, and
CALL PLCWRITE commands in general. Most of the PLC Interfaces
developed so far use the same arguments for similar functionality, no matter
which Interface is installed. Exceptions are noted in the tables. More specific
information follows in sections particular to each Interface Option.
Refer to the section for your PLC to see if the “normal” implementation for a
given function is different for you PLC. See the PLC and SLC specific
sections on the -PL5 and -SL5 Options for the CALL PLCREAD and CALL
PLCWRITE commands for the Allen Bradley PLC-5 and SLC 500 PLC’s as
they are significantly different from the rest of the interface options.
