Tip
• Assign the I/O numbers in the following order: Q Series to A Series or A Series to Q Series.
• When the order is mixed (i.e., Q Series -> A Series -> Q Series), the CPU does not start up due to an error.
•‥The‥I/O‥addresses‥do‥not‥need‥to‥be‥changed‥when‥reutilizing‥existing‥A‥(Large‥Type)‥and‥AnS‥

● System configuration example of I/O assignment (1) I/O assignment example
When utilizing existing AnS (Small Type) modules with the L Series CPU, set the existing module's I/O addresses to the existing addresses with the PC parameter I/O assignment settings. Assign the addresses for the modules mounted onto the main base unit after the existing module. This will greatly reduce the program modification time.

3.4.2 When replacing with L Series
The following is an example of how to reuse the program without modifying the I/O addresses when replacing the CPU with an L Series CPU and keeping the existing I/O modules on a LA1S extension base unit.

The following is an example of replacing a MELSECNET(ΙΙ) coaxial loop system's master station with a Q Series system and upgrading the network to a MELSECNET/10 coaxial bus system.
● Instructions
(1) Replace one of the MELSECNET(ΙΙ) stations with the Q Series.
(2) Replace the complete MELSECNET(ΙΙ) system with MELSECNET/10 coaxial bus system.
(3) Replace the CPU of each station with Q Series CPU sequentially, and eventually replace all CPUs with Q Series CPUs.
(4) Use the existing settings for the network parameters.
•‥ When‥an‥existing‥MELSECNET(ΙΙ)‥system‥consists‥of‥many‥stations,‥the‥complete‥network‥
system‥can‥be‥upgraded‥to‥MELSECNET/10‥while‥reusing‥existing‥cable‥installations.
•‥ By‥upgrading‥the‥entire‥network‥at‥once,‥the‥current‥network‥parameter‥settings‥can‥be‥used.
•‥ Once‥the‥network‥is‥updated,‥A‥Series‥stations‥can‥be‥replaced‥with‥the‥Q‥Series‥in‥any‥order‥
until‥all‥the‥stations‥are‥upgraded‥to‥the‥Q‥Series.
