HHP Features
The HHP has a sealed-type keypad with tactile feedback and 42 keys, arranged in a matrix of six
keys across by seven keys down. It has a two-line by 16 character LCD display screen.
HHP Memory Card (IC693ACC303)
The HHP has a slot for a removable memory card , which provides a means for non-volatile, off-
line program storage and restoration. The memory card can only be used with CPU numbers 311
through 341. CPU numbers 350 and above do not support either the HHP or the memory card.
The memory card plugs into a connector accessed through a slot on the lower right side of the HHP
(see previous figure).
HHP Modes of Operation
The HHP functionality is basically divided into four modes of operation that are selected through a
key sequence on the keypad.
Program Mode:
Allows you to create, change, monitor, and debug Statement List logic. This mode also
allows read, write, and verify functions with the memory card, EEPROM, or flash
memory.
Protection Mode
Provides a way to control access to (protection of) certain PLC functions, including
program logic, reference data, and configuration information. The use of this function is
optional; however, it is convenient in that it allows you to protect parts of the PLC system
from accidental or deliberate modification. Protection is provided through four levels of
passwords assigned by the user.
Data Mode
Allows you to view, and optionally alter values in various reference tables. Several
display formats can be selected in which to view this data: binary, hexadecimal, signed
decimal, and timer/counter.
Configuration Mode
Allows you to define the types of I/O modules installed in the PLC system. You can also
assign I/O module addresses to these modules. This feature is convenient in that it allows
you to write and test logic programs using discrete references assigned to I/O modules that
are not yet installed. In this mode, you can also configure CPU data, such as real-time
clock , coil check, and HHP characteristics, such as keyclick on or off.
