Precautions for Correct Use
Precautions for Correct Use
Functions will vary as shown below depending on whether allocations are set with the use of CX-
Integrator or through device variable for CJ-series Unit (Master User-set Allocations Setup
Table.)
•
You can determine the order of node addresses when the CX-Integrator is used. Words are
always allocated to slaves in order of ascending node addresses when allocations are set with
device variable for CJ-series Unit. However, even when you use device variable for CJ-series
Unit, nodes do not have to be allocated words, reducing the number of words required.
•
There are four blocks (OUT1 and 2 and IN1 and 2) available when setting is made with the CX-
Integrator, but you can only allocate two blocks (OUT1 and IN1) with device variables for CJ-
series Unit.
•
The first bit for node allocations can be either bit 00 or bit 08 when setting allocations with CX-
Integrator (allocations for slaves with two bytes or more cannot start at bit 08), while it is
always bit 00 with device variable for CJ-series Unit.
