1.1 Use

The CMU module (model LQP520, LQP525 or LQP527) is used in conjunction with an S10V
LPU module to speed C mode (C language/HI-FLOW) P-coil processing. As a communications
interface, it also supports communication under TCP/IP or the UDP/IP protocols by way of a
local area network complying with the IEEE802.3u specifications (100BASE-TX) and IEEE802.3
specifications (10BASE-T).
The model-LQP525 or LQP527 CMU module can be used in the same way as the model-LQP520
CMU module. However, if the former model is used in conjunction with a battery module
(model LQZ500), it can back up internal work area in its memory.
