Q: How can I get the status of digital Input ports?

A: CIE-H10/M10 is a remote digital I/O controller. And it is also equipped with ability to convert TCP/IP to Serial. So, those interfaces are various compared with other ezTCP.

[INTERFACES OF DIGITAL I/O]
Each digital input is interfaced with photo-coupler and the output is a relay. You can change the type of digital input to the "dry-contact" by using a Dry-Contact Adapter(DCA) which we've offering.

[INTERFACE FOR Serial Device Server]
DB-9 PIN Male connecter and RJ45 for Ethernet are equipped.

Q: Then, is that means the role for serial device server and digital I/O controller are independent?

A: Yes, it is. However, recently we added a mode which is named "Serialized Modbus/TCP" for monitoring and controlling I/O ports through serial port.
In this mode, the data which has a format of Modbus/TCP frame is sent and received via RS232 port. When you make a program for communication with CIE-H10/M10, the information about this format is needed.

We think it will be a no problem to make program with this protocol, because it uses minimum class of that. Only two function codes are using and each master and slave has their fixed format.

Are there any sample codes or references?

We've been offering a sample code and technical document about the protocol. Please refer to them.
1. Sample code for Visual C++
2. Sample code for Visual Basic
3. Technical Document: Modbus/TCP

Dry Contact Adapter (DCA) is introduced!

 

DCA is introduced for CIE-H10.

The adapter is for changing input type of CIE-H10 to dry contact.

That means you can input HIGH to each input port by relay (or switch).

 

 

 

<Usage>

1. Just put it on the input side.

 

 

2. Supplying power (DC 4 ~ 25V) through the DC port.

 

 

3. Connect switch or another relay to any ports.

New F/W of ezTCP

 

Some of ezTCP’s Firmwares have been changed.

The versions are followed

 

EZL-200F: 1.3I -> 1.3J

CSE-M32/H20/H21: 1.2H -> 1.3A

CSE-M73 -> 1.4D -> 1.5A

CIE-H10/M10 -> 1.3C -> 1.3D

 

[Major points of the changes]

 

1. Add the AT+PSE command in ATC mode: CSE-M32/H20/H21/M73/CIE-H10/M10

 

AT command lets users operate ezTCP as a TCP server or client.

When TCP connection is established, if you send three escape code “+++”, you can change the Online mode to AT command mode. Doing it, the “+++” character must be sent to your remote host. However, some people didn’t want to send it. To solve this problem, AT+PSE command has been added.

The usage is like this

 

AT+PSE=0

AT+PSE=1

 

It’s quite simple.

If the value is 0, the characters are not sent. The default value is “1”

 

2. Add the MAC ID function: CSE-M32/H20/H21/M73/CIE-H10/M10

 

MAC ID function is for identification with its MAC address.

Checking this option, ezTCP will send its MAC address to the remote host right after the connection is established. The option is available on both TCP server and client mode.

 

The options can be configured by ezManager.

(New ezManager(ver.3.0c) is being developed and tested now. And it will be released soon. You can use the option with it.)

 

For your information, EZL-200F has a similar option with this.

 

3. Multi Monitoring in RS422/485 connections: EZL-200F

 

As you know, EZL-200F supports multi monitoring option. 8 different hosts can be connected with the model in the same time. This option was available on RS232 connection in previous F/W. New F/W has been changed at this point.

You can use the option in RS232/422/485.

 

We are always thinking about users’ convenience in using our products. So, we have been adding a lot of options on their firmware. Thus, we recommend that users always use the latest version of firmware. The file will be on our website.

Customers can interface between CIE-H10 and dry contact sensors (switch, relays) by the following two methods.

What is dry contact?
A dry contact is a contact that does not provide voltage.

A. Using Dry Contact Adapter(DCA)
  - Customers can implement dry contact interfaces very easily with Dry Contact Adapter (DCA).
  - An Additional DC power is required for DCA.
  - DCA will be provided from August 2009.

B. Implementing Dry Contact Interface
  - CIE-H10's input ports sense DC voltage from sensers.
  - Above 1.8V: 1(ON), Below 1.5V: 0(OFF)
  - Therefore, users have to implement as vollowed for Dry Contact Sensors.

  - DC valtage of input port is DC 1.8V ~ 24V. But we recommend users to use a DC 5V ~ 24V power supply because of cable resistance.
  - We recommend users to use isolated DC Power.

Let’s look at the ISP mode

 

In System Programming (ISP) mode

 

Q: What is the ISP mode?

 

ISP mode is one of states for upgrading firmware of ezTCP series. This mode is also used about solving problem with password for most of ezTCP. When you’ve forgot the configured password on your ezTCP, ISP mode will help you. In ISP mode, password and an option accessing to its configuration tool (ezManager / ezConfig) do not working.

 

Q: Then, can I use this mode all the time?

 

The answer would be No!

The TCP connection or data communication is impossible in this mode. So, you should use this mode when you are faced with above two situations.

 

Q: How can I get enter the mode?

 

The ways could be different on their types.

 

EZL-50R/50A/50L/50M

Pull-down the ISP- pin and then, reset or resupply the power to the product.

In case of using evaluation board, connect the jumper to the ISP position and reset or resupply the power.

 

EZL-60/60L/60M

Place the JP1 (ISP jumper) to ISP location for making a short circuit of those two pins. And then, reset or resupply the power.

 

EZL-70/CSE-M73

Connect the ISP jumper (EZL-70: JP1, CSE-M73: JP6) for making a short circuit of those two pins. And then, reset or resupply the power.

 

EZL-200L

Press the ISP button by RJ45 connector over 3 seconds in normal mode. Or, resupply the power while pressing the button.

If EZL-200L is in ISP mode, the STS LED will be blinks very quickly.

 

EZL-200F

Resupply the power while pressing the ISP button located by RJ45 connector.

If EZL-200F is in ISP mode, the STS LED will keep on.

 

EZL-410

Pull-down the ISP- pin on JP1 and then, reset or resupply the power.

In case of using evaluation board, place the jumper on JP5 to ISP location and reset or resupply the power.

 

EZL-300S/400S

Both products don’t have ISP mode. The firmware download will be implemented in telnet connection.

 

CSE-M32

Pull-down the ISP- pin and then, reset or resupply the power.

In case of using evaluation board, locate the jumper on JP5 to ISP location and reset or resupply the power.

 

CSE-H20/H21/CIE-H10
Press the ISP button over 1 second. Or, resupply the power while pressing the button.

If the products are in ISP mode, their STS LED will keep off.

 

CSP-H50

Reset the power pressing the ISP button or input “pf” in command mode.

 

EZL-300L/90

Resupply the power without wireless LAN card. The products will be operated as ISP mode for the first 2 seconds. If there are no inputs for the time, the mode will change to console mode.

 

CSW-H80

Resupply the power pressing the function button. Or, press the button over 1 second.

 

Q: How can I upgrade the Firmware?

 

Each manual of products indicates details of the process.

 

Here is a something you should know.

 

Products called ezTCP/LAN, EZL-50/60 series, EZL-70, 200L, 200F, 220, 410, 400S, CSE-M32, M73, H20, H21 and H10, can download the F/W through the Ethernet port.

 

Products called ezTCP/WLAN, EZL-80 series, EZL-300L/S and CSW-H80, can download the F/W through the serial port.

Using CIE-H10 as a Wireless LAN I/O Controller Ⅱ

CIE-H10 can be operated on Wireless LAN with CSW-H80.
CSW-H80 is a serial to Wireless LAN converter.
To use this, CIE-H10 has to be set to "Serial Modbus/TCP" mode.
This mode is a serialized Modbus/TCP mode.
In this mode, CIE-H10 receives Modbus/TCP data from RS232 Port.
So, we shold connect the CIE-H10 with CSW-H80 thgouth RS232 cross cable.
Or, it is okay to connect pin #2 (RXD), #3 (TXD) and 5(GND).
(RXD)  #2 ---------------- # 3 (TXD)
(TXD)   #3 --------------- # 2 (RXD)
(GND)  #5 --------------- #5 (GND)

Used devices & program
- CIE-H10
- CSW-H80
- AP:G104M (EFM networks)
- ezManager(v2.0j)

We used ezManager v2.0j on this test because the Modbus/TCP test program of new ezManager v.3.0a could not manually input peer IP address.
It's just an exmple.
So, you can try it any Modbus/TCP client.
