CAN bus
The communication between the main module and the expansion modules or the remote
I/O happens over a CAN bus. CAN is a widely used bus system（only ELC-18 Series
available, not applied to ELC-12 series
）
Note
xLogic Main Module may be equipped with expansion modules of the different voltage
class, but expansion module must be supplied the correct power corresponding to its
type.
Each xLogi c Main Modul e provides the fol lo win g connections for the
creation of the circuit program, regardless of the number of connected blocks:
Digital inputs I1 to IC（ELC-18），I1 to I8(ELC-12).
Analog inputs AI1 to AI8
Digital outputs Q1 to Q6（ELC-18），Q1 to Q4(ELC-12)
Shift register bits S1 to S8
4 cursor keys
