5. Press down firmly to lock the module in place, but do not use excessive force.
6. Power up the PLC rack. The OK LED (top LED) on the faceplate of the PCM begins
to flash during power-up diagnostics if a PLC CPU has been installed in the rack.
When the PCM successfully completes diagnostics, it continues to flash while
waiting for configuration data from the CPU. Once the PCM is ready, this LED
should be continuously on.
Adding Expansion Memory to the Series 90-70 PCM
To increase the total available memory, an expansion memory daughter board may be
added to a Series 90-70 PCM. The daughter board mounts on a single connector on the
PCM. Expansion memory cannot be added to a Series 90-30 PCM.
Four versions of the expansion memory board are available:
Table 2-1. Expansion Memory Boards
Catalog Number
Memory Size
IC697MEM713 64K Bytes
IC697MEM715 128K Bytes
IC697MEM717 256K Bytes
IC697MEM719 512K Bytes
To mount the daughter board, follow these steps:
1. Touch an exposed metal surface of the PLC rack in order to discharge any
electrostatic charge you may have.
2. Power down the Series 90-70 PLC system, and remove the PCM.
3. Remove the memory expansion module from its anti-static bag.
4. Carefully align the pins on the bottom side of the daughter board with the connector
on the PCM.
5. Align the holes on the opposite end of the PCM with the daughter board standoffs.
6. Push the daughter board into the connector.

7. Make sure the daughter board is fully seated and the standoffs are snapped into
both boards.
If an expansion memory board is installed on a PCM that has already been configured
for no expansion memory or for a different expansion memory size, the Logicmaster 90
configuration must be updated and stored to the PLC CPU.
