6.24 Serial Communication FunctionNote67Note68
(1) Definition
The serial communication function is designed to make communication in the MC
protocol
*1
by connecting the RS-232 interface of the CPU module and personal
computer, display device or the like by an RS-232 cable.
The serial communication can be executed by the Q00CPU or Q01CPU only.
(The other CPU modules do not support the serial communication function.)
The following explains the specifications, functions and various settings needed to
make communication with a personal computer, display device or the like using the
serial communication function.
* 1 : The MC protocol is the abbreviation of the MELSEC communication protocol.
The MELSEC communication protocol is a name of the communication method to make access
from the mating equipment to the CPU module in accordance with the communication procedure
of the Q series PLC
Refer to the following manual for the MC protocol.
Q Corresponding MELSEC Communication Protocol Reference Manual
POINT
1. The CPU that can make communication with a personal computer, display
device or the like using the serial communication function is only the CPU
module that is connected with the personal computer, display device or the
like.
Communication cannot be made with the other station of MELSECNET/H,
Ethernet or CC-Link via the CPU module that is connected with the personal
computer, display device or the like.
2. The serial communication function is not used for connection of GX
Developer or GX Configurator and CPU module.
