2 SYSTEM CONFIGURATION

2.1.4 Restrictions on Motion systems

(1) Combination of Multiple CPU system

(a) Motion CPU module cannot be used as standalone module.

Be sure to install the universal model PLC CPU module to CPU No.1.

For Universal model PLC CPU module, "Multiple CPU high speed

transmission function" must be set in the Multiple CPU settings.

(b) Only Multiple CPU high speed main base unit (Q35DB/Q38DB/Q312DB)

can be used.

Q172DCPU(-S1) and Q173HCPU(-T)/Q172HCPU(-T)/Q173CPUN(-T)/

Q172CPUN(-T) cannot be used.

The combination of Q173DSCPU/Q172DSCPU/Q173DCPU(-S1)/

Q172DCPU(-S1) can be used.

(d) Up to four modules of universal model PLC CPU modules/Motion CPU

modules can be installed from the CPU slot (the slot on the right side of

power supply module) to slot 2 of the main base unit. CPU modules called

as CPU No.1 to CPU No.4 from the left sequentially.

There is no restriction on the installation order of CPU No.2 to No.4.

For CPU module except CPU No.1, an empty slot can be reserved for

addition of CPU module. An empty slot can be set between CPU modules.

However, the installation condition when combining with the High

performance PLC CPU module/Process CPU module/PC CPU module/C

controller module is different depending on the specification of CPU

modules, refer to the Manuals of each CPU modules.

(e) It takes about 10 seconds to startup (state that can be controlled) of Motion

CPU. Make a Multiple CPU synchronous startup setting suitable for the

system.

(f) Execute the automatic refresh of the Motion CPU modules and universal

model PLC CPU modules by using the automatic refresh of Multiple CPU

high speed transmission area setting.

When the High performance PLC CPU module/Process CPU module/PC

CPU module/C controller module is installed in the combination of Multiple

CPU system, the Motion CPU module cannot be execute the automatic

refresh with these modules.

(g) Use the Motion dedicated PLC instructions that starts by "D(P).". The Motion

dedicated PLC instructions that starts by "S(P)." cannot be used. When the

High performance PLC CPU module/Process CPU module/PC CPU

module/C controller module is installed in the combination of Multiple CPU

system, the Motion dedicated PLC instruction from these modules cannot be

executed.
