Simple I/O Allocation Section 4-2
Procedure Overview
Note The sizes of slave I/O data allocated in the master is listed below. Allocate I/O
correctly within the maximum allocation sizes.
DeviceNet Communications Unit allocation sizes:
IN Area: Up to 200 bytes (100 words)
OUT Area: Up to 200 bytes (100 words)
CS/CJ-series Master Unit allocation sizes:
IN Area: Up to 200 bytes (100 words)
OUT Area: Up to 200 bytes (100 words)
CVM1/CV-series, C200H, C200HX/HG/HE Master Unit allocation sizes:
IN Area: Up to 64 bytes (32 words)
OUT Area: Up to 64 bytes (32 words)
4-2 Simple I/O Allocation
4-2-1 Setting Allocation Data
Simple I/O allocation is used to allocate I/O in the master without using a Con-
figurator, and to allocate in the master the Temperature Controller set points
(SP), process values (PV), alarm output status, and other basic data only.
Set simple I/O allocation by turning ON pin 1 of the DIP switch on the rear of
the DeviceNet Communications Unit.
When simple I/O allocation is used, basic data such as the predetermined PV
and SP for each of the connected Temperature Controllers is allocated in unit
number/channel order for the maximum number of Temperature Controllers
set using the rotary switch on the rear of the DeviceNet Communications
Unit’s.
The allocation size is determined according to the unit number (0 to 15) set on
the DeviceNet Unit’s rear panel DIP switch.
• IN Area: 16 to 46 words (= 16 + n
×
2 words)
• OUT Area: 8 to 38 words (= 8 + n
×
2 words)
Steps Simple I/O allocation I/O allocations from the Configurator
Step 1 Set the allocation
data. Turn ON pin 1 of the rear panel DIP switch. Turn OFF pin 1 of the rear panel DIP switch.
IN Area: 1 block
OUT Area: 1 block
IN Area: 2 blocks
OUT Area: 1 block
Using the Configurator, create the allocation
data in the Edit Device Parameters Window for
the DeviceNet Communications Unit.
--- Using the Configurator,
set the connections using
user definitions in the Edit
Device Parameters Win-
dow for the Master Unit.
Step 2 Allocate the data
in the master. Fixed allocations User-set allocations
Using the Configurator,
allocate I/O from the
Edit Device Parame-
ters Window for the
Master Unit under I/O
Allocations, or I/O Allo-
cations through Allo-
cated DM words. Fixed allocations User-set allocations
Using the Configurator,
allocate I/O from the Edit
Device Parameters Win-
dow for the Master Unit
under I/O Allocations, or
I/O Allocations through
Allocated DM words.
