Two optional memory modules are available for the MicroLogix 1000 HHP:
•
8 Kbyte memory module, 1761-HHM-K08 – stores 1 program (possibly
more than 1, depending on program size)
•
64 Kbyte memory module, 1761-HHM-K64 – stores a minimum of
8 programs
For information on loading and storing programs to your memory module,
see page 19–1.
!
ATTENTION: Always remove power from the HHP before
inserting or removing the memory module. This guards against
possible damage to the module, as well as undesired controller
faults.
!
ATTENTION: To avoid potential damage to the memory
modules, handle them by the ends of the carrier or edges of the
plastic housing. Skin oil and dirt can corrode metallic surfaces,
inhibiting electrical contact. Also, do not expose memory
modules to surfaces or areas that may typically hold an
electrostatic charge. Electrostatic charges can alter or destroy
memory.
To insert a memory module use the following procedure:
1. If the MicroLogix 1000 HHP is connected to the controller, remove the
cable from the HHP or turn off power to the controller.
2. Remove the memory module door.
3. Locate the socket on the processor board. Place the memory module onto
the socket and press firmly in place.
4. Replace the memory module door.
5. If the MicroLogix 1000 HHP was connected to the controller, reconnect
the cable to the HHP, or restore power to the controller.
