1.1 Use
The CPU link module (Model LQE550) is a communications module that provides inter-CPU
data exchange.
When this module (Model LQE550) is used with the S10mini’s CPU unit, it is allowed to coexist
with the Model LQE050 CPU link module, which is specially designed for use with the S10mini
(the LQE050 cannot be used with the S10V’s LPU unit).
