CJ-series PROFINET IO Controller Unit Operation Manual for NJ-series CPU Unit (W511)
A-1 Differences in Available Functions
Depending on the CPU Unit (NJ/CJ-
series) to be Connected
Some functions available to the CJ series may be unavailable when you operate this Unit with the NJ
series.
The following table lists the differences between the NJ and CJ series for each function that this Unit
provides.
When this Unit is operated with an NJ-series device, a user program accesses various functions pro-
vided by the PROFINET IO Controller Unit through a device variable for CJ-series Unit that specifies AT
specification for the memory used for CJ-series Unit.
The corresponding word addresses, bit positions, and device variables of CJ-series CPU Unit's I/O
memory and NJ-series CPU Unit's CJ Unit memory are listed below.
First word of Special I/O Unit CIO Area: n = 1,500 words + Unit number × 25 (Unit number: 0 to 15)
First word of Special I/O Unit DM Area: m = D30,000 words + Unit number × 100 (Unit number: 0 to 15)
Additional Information
The DM area words which are allocated for the PROFINET IO Controller Unit are not used, i.e.
no data is exchanged between an allocated DM area and the Unit. However, the allocated area
is reserved for use in a future extension of the Unit. Therefore, using this area for user data is not
recommended.
