2 SYSTEM CONFIGURATION
(7) Online module change
In the following cases, the online module change cannot be performed.
(a) When an extension base unit (type requiring no power supply module)
(Q52B, Q55B, Q55BL, Q55BLS, or Q55BLS-D) is used (No module
mounted on any extension base unit can be changed online.)
(b) When a slim type power supply module (Q61SP) is used
(8) MELSECNET/10 mode
The MELSECNET/10 mode can be set with the remote I/O module whose serial
No. (first five digits) is "15012" or later.
(9) Precautions for mounting an intelligent function module
Note that the number of intelligent function module parameters that may be set
(initial setting, automatic refresh setting) is limited on the remote I/O module.
If the number of parameters set exceeds the limited number, the remote I/O
module detects the "SP. PARA ERROR (3301)" error.
To auto refresh the excessive parameters, use the REMFR/REMTO instruction to
read/write data from/to the intelligent function module.
Item No. of the parameters that can be set
Initial setting Up to 512
Auto refresh setting Up to 256
The number of parameters for initial setting is fixed for each intelligent function
module. To check the numbers of parameters for initial setting, refer to the user's
manuals for the corresponding intelligent function modules.
For the way to count the number of parameters for automatic refresh setting,
refer to Section 5.2.1 (4).
