(2) Modules with restrictions when used with the Built-in Ethernet port QCPU
The following table lists modules with restrictions when used with the Built-in Ethernet port QCPU.
Product
MELSECNET/H module
Serial communication module
Web server module
MES interface module
*1 If the following conditions are all met, use the MELSECNET/H module whose serial number (first five digits) is "10042" or
later.
1) A multiple CPU system containing the Built-in Ethernet port QCPU is configured.
2) A programming tool or GOT is connected to an Ethernet port of the Built-in Ethernet port QCPU.
3) The programming tool or GOT connected accesses another station via the MELSECNET/H module controlled by
another CPU module.
4) The access target CPU module on another station is A/QnA series.
(3) Number of available slots
Empty slots are included in the number of available slots (modules) in the base unit.
(One slot is occupied even when "empty" and "0 points" are set for the slot 2 as shown in the following figure.)
The number of available slots (modules) varies depending on the base unit.
Page 223, CHAPTER 8
For the assignment concepts of base units and I/O numbers, refer to the following.
User's manual for the CPU module used (Function Explanation, Program Fundamentals)
(4) Power capacity
The power may be insufficient depending on the combination of the mounted modules or the number of the
mounted modules. When mounting modules, consider the power capacity.
If the power is insufficient, change the combination of modules so that the power is sufficient.
(5) External devices connected to Built-in Ethernet port QCPU
When connecting external devices to Built-in Ethernet port QCPU, power off the module and the external devices
before connecting.
