*1. "Packets per second" is the number of communications packets that can be processed per second.
*2. When using the EtherNet/IP Unit with version 3.0 or later. When using the EtherNet/IP Unit with version 2.1 or earlier,
       the maximum allowed communications bandwidth per Unit is 6,000 pps. When using the EtherNet/IP Unit with version
       3.0 or later, the Network Configurator with version 3.57 or higher is required.
*3. Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the
       data size. Application is supported between CS/CJ-series PLCs. When connecting to devices from other
       manufacturers,make sure that the devices support the Large Forward Open specification.
*4. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.
*5. When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition,
       a timeout will temporarily occur at the other node that was communicating with that port, and it will then recover
       automatically.
*6. The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using a switching
       hub that supports IGMP snooping.

	Remote Programming and Monitoring			Host Link communications can be used for remote programming and remote monitoring through a Controller Link, Ethernet, DeviceNet, or SYSMAC LINK Network. Communications across network layers can be performed. Controller Link or Ethernet: 8 layers DeviceNet or SYSMAC LINK: 3 layers
	Automatic Online Connection via Network		Direct Serial Connection	This function enables automatically connecting to the PLC online when the CX-Programmer is directly connected by a serial connection (peripheral (USB) port or serial port).
			Via Networks	This function enables connecting the CX-Programmer online to a PLC that is connected via an EtherNet/IP network.
Security	Read Protection using Password			This function protects reading and displaying programs and tasks using passwords. Write protection: Set using the DIP switch. Read protection: Set a password using the CX-Programmer.
	FINS Write Protection			This function prohibits writing by using FINS commands sent over the network.
