GENERAL DESCRIPTION
The Gould Modicon Programmer/Tape Loader
cartridge, used in conjunction with the Micro 84
Programmable Controller, the J375 Modbus
7j
Adapter, and the P190 full-family CRT Program-
mer, provides programming functions for program
preparation, editing, documentation, debug, and
system maintenance. With Programmer/Tape
Loader, the user can perform local programming
functions on the plant floor or expand the Micro
84 controller’s versatility by performing remote
programming and tape loading operations. In
addition, it provides control for starting and
stopping the Micro 84 controller, reporting its
configuration, and writing the program pack.
There are two programming options:
Element
Editing
and
Network Editing. Element Editing
per-
mits the user to make entries and/or changes
directly into the Micro 84 controller’s memory.
Network Editing
permits the user to make changes
in the PI90 programmer’s memory before making
changes in the Anicro 84 controller’s memory. With
Network Editing,
the user can experiment with
network changes while preserving existing logic.
Both editors can read existing networks, create
new networks, edit networks, disable and force
j
elements, report full or partial reference tables,
report coil usage tables, and perform element
searching.
Network Editing
offers the additional
capability of deleting, replacing, exchanging,
compressing, and expanding networks.
Four Tape Loader functions allow the user to:
1.
2.
3.
4.
Load
from the P190 tape to the Micro 84.
Record
the Micro 84 memory onto the P190
tape.
Compare
the Micro 84 memory with the P190
tape.
Write the Micro 84 memory onto the program
track.
The
Load
function allows the user to construct
new programs by loading and later editing selected
networks from a previously prepared program.
Record
enables the user to preserve a copy of the
program on a P 190 tape for later use. A program
may also be recorded on a Micro 84 program pack
by Writing the program pack function.
Compare
is used to verify that the Micro 84 con-
troller’s memory contains the same program as
that on a P190 tape. Comparison may be per-
formed on all memory, selected networks, or
selected registers. The user may also select a
log-and-pause or continuous-log mode for report-
ing miscompares.
The Programmer/Tape Loader cartridge plugs
directly into the PI90 tape transport. Local use
requires a Gould Modicon J375 Modbus Interface.
Remote use requires a J375 plus Gould Modicon
J378 and J478 modems (or commercial equiva-
lents). A P190 cable (either AS-W806-OXX or
AS-W364-OXX) provides the communications
link between the PI90 and J375. When using a
J375, the user must set port parameters and address
selection on both the J375 and P190 programmer.
A hard copy printout of the P190 programmer’s
CRT screen is obtained by connecting an RS-232-C
compatible printer to the PI 90 programmer’s
second communications port.
