Chapter 2 Specification of Communication port for CPU

module

2.1 Features

EHV-CPU has three communication ports as follows.

(1) Ethernet communication port

(2) Serial communication port

(3) USB communication port

Figure 2.1 Communication port

(1) Ethernet communication port

EHV-CPU has 4 ports as a task code dedicated port for communicating by the dedicated protocol of H series.

Programming and monitoring are possible by connecting the Control Editor. This port can also connect with a monitor

available on the market corresponding to the H series dedicated protocol.

And since the ASR communication function is supported, transmitting and receiving message data are possible by the

simple setting. Message data are transmitted at the event occurrence or periodically, and received automatically.

Therefore, the network configuration matching to the system can be constructed.

In addition, since the SNTP client function is supported, the time information can be taken from the NTP server and

the SNTP server on the network, and the time can be revised automatically. (Refer to NTP client function in this

chapter for the SNTP client function.)

(2) Serial communication port

EHV-CPU supports RS-232C, RS-422, and RS-485 as a communication interface of the serial communication port.

And also it supports a dedicated port for communicating by the H series dedicated protocol as the communication port

and a general-purpose port which can control communication by a user program.

In the dedicated port, programming and monitoring are possible by connecting the Control Editor. This port can also

connect with a monitor available on the market corresponding to the H series dedicated protocol. In addition, since the

model connecting function is supported (only RS-232C), communication of the programming software via the model

can be realized.

In the general-purpose port, since communication can be controlled by the user program, communication with external

devices with the serial communication port is possible.
