3 COMMON PARAMETERS

3.2 I/O number assignment

In the Multiple CPU system, I/O numbers are used for interactive transmission

between the Motion CPU and I/O modules and intelligent function modules, or

between PLC CPU and Motion CPU.

3.2.1 I/O number assignment of each module

The Multiple CPU system is different from the Single CPU system in the position (slot) of

I/O number "0H" for PLC CPU.

However, I/O number of control module can be assigned independently for each CPU for

Motion CPU.

(1) Position of I/O number "0H"

(a) The number of slots set with the Multiple CPU settings are occupied by the

PLC CPU/Motion CPU on the Multiple CPU system.

(b) I/O modules and intelligent function modules are installed from the right of the

slots occupied by PLC CPU/Motion CPU.

each CPU.

The I/O number of PLC CPU control module for an I/O module or intelligent

function module mounted to the next slot to those occupied by CPU modules

is set as "0H" and consecutive numbers are then allocated sequentially to the

right.

(d) Notation of I/O number

• Receiving of ON/OFF data by Motion CPU is deemed input (PX), while

outputting of ON/OFF data from Motion CPU is deemed output (PY).

• I/O number is expressed in hexadecimal.

REMARK

1) If the number of CPU modules installed on the main base unit is less than the

number set at the "Multiple CPU setting", set the open slot(s) to "PLC (Empty)".

Refer to Section 2.1.2 for the "PLC (Empty)" setting.

2) The I/O numbers for the Multiple CPU system can be confirmed with the system

monitor of GX Developer.
