What to do when you see an error message: “The system cannot find the file specified.”


Have you ever used [Import Variables] and [Export Variables] on ezManger or ezConfig? These functions are very useful when you are supposed to set the same environmental parameters to multiple ezTCP products or save parameters to set another ezTCP identically same afterwards.

In short, these are to back up ezTCP parameters.

Meanwhile, you may find the error message below while using these functions. If it happens, check the following things and it will simply sorted out.


1. Check the version of configuration tools

Old versions of ezManager or ezConfig may lead to problems on recognizing the latest products and the error message will be popped up. To prevent it, it is highly recommended to stay up-to-date with the programs.

2. Check if it is the same product with the one you saved with [Export Variables]

[Import Variables] and [Export Variables] are available to the same product only. For example, if you once save environmental parameters of CSE-H25 and try setting the same parameters to CSE-H53N using [Export Variables], it won’t work at all.


Output Port Pulse Control With User Webpage Javascript

Sollae Systems’ remote I/O controllers, except for EZI-10, enable users to upload their own webpages to monitor input ports and control output ports.

Basically you can control some special performances as well as basic ones on the webpages with Javascript. So, in this article, we will go through how to enable pulse control of output ports using Javascript.

Pulse output is generally to keep changing states – high or low- on a regular basis. But this time we will write a code to make it stayed for specified time as it set time and back to the original state.

For this demonstration, we will use an 1-port remote I/O controller,  CIE-H12 which comes preloaded with the following source code.

Output Port Pulse Control With User Webpage Javascript_1


Let’s add Javascript above #head# as follows.

Output Port Pulse Control With User Webpage Javascript_2

Output Port Pulse Control With User Webpage Javascript_3

Now the output port of CIE-H12 will have an output value for specific time and get back to normal as it was.


Output Port Pulse Control With User Webpage Javascript_4

“2000″ represents 2,000ms, which means 2 seconds, so the output port will stay ON for 2 seconds and back to OFF.

The video below will show you how CIE-H12 works in real.

▼ Set to 100ms


▼ Set to 500ms


▼ Set to 1,000ms


▼ Set to 2,000ms


You can also do pulse control with a ‘P’ tag supported by firmware ver. 1.5A.

Turning On/Off A Warning Light Using CIE-M10 And A Relay Module

This is a demonstration of how to turn on/off a warning light using a relay module available to interwork with CIE-M10.

Before getting started, we would like to introduce CIE-M10, 8-port remote I/O module. It supports 8 digital input/output ports and 1 analogue input port. It mainly enables you to extend the distance of the I/O control system so that you can remotely control and monitor your I/O devices over the Internet from anywhere in the world.

The following link will guide you to find more details.



To turn on/off lights or control user devices by digital output signal of CIE-M10, its output ports should be interfaced with a relay, SSR, etc.

We provide a user manual to demonstrate relay interface using CIE-M10, however, it is difficult to interface relays for those who have no knowledge on circuit and hardware, while it may be easy for those who have a lot of experience. This article, therefore, is to help you to get over this difficulty by showing you how to control output ports of CIE-M10 with a common relay module.

We looked for a proper relay module and bought an 8-port one – because CIE-M10 supports 8 ports of digital output- and additional 4-port one on the Internet.

The relay interface circuit below has already been interconnected, so the only thing you need to manage is to connect VCC, GND and each output signal to each socket at the bottom of the module. Pannel input voltage of it is 5V, 400mA.



Then, through the warning light, we checked if it really affected to the relay contacts when we control CIE-M10, relay module and output ports.

Although we used a cable to make it look neat, we actually connected  3.3V input and GND to CIE-M10 and also Do0~Do7 output ports of it to the #1~7 of the relay module. Additional 5V input is applied to the relay module, so two GND of each input should be connected.



You may refer to the following image before carrying out the above.

3.3V input (#27, #28)

GND (#29, #30)

Do0~Do7 (#9~16)



We accessed to a web page of CIE-M10 and tried controlling output port #1(Do0) attached to the warning light. You can find the Do0 on the web page, the first relay LED and the warning light were changed to “ON”.




If you are one of those who chose CIE-M10 other than external type of remote I/O controllers (CIE-H10/CIE-H14) to escape price burden but struggling with problem on hardware interfacing, it can be a useful solution to develop an application using commercial products available to interwork with CIE-M10.



cieManager, Modbus/TCP program, for Android

We are glad to introduce to you an Android smart application, “cieManager”, for CIE-H12, CIE-H14 developed by our reseller in Poland, ELFAN s.c.

You can download it at Google Play store. – It’s totally free of charge!



Installing it to your smartphone, you will see the following icon created.



This is an initial screen of cieManager. The interfaces to control CIE-H14 are very neat and well arranged.



You can find four buttons showing up when you click the [Menu] button: [Connect] and [Disconnect] for access management and [Settings] for access configuration.



[Settings] is for configuring properties. – IP address, port number, poll time and so on.



The following image is for CIE-H12. Interface is changed depending on products.



You can find ELFAN s.c. info including a website if you click the [About] button.



Polish is supported as well as English.



We tested this app with CIE-H14.

Once Inputting power to input port #3, the colour was changed to green. Relay output ports were also changed to green as soon as clicking them.



This app seems very useful for those who want to control each contact wirelessly.

To do is so, however, some simple network knowledge is required.

Firstly, you should connect your smartphone with a wireless router and connect CIE-H14 with the same router through a LAN port.

Secondly, you need to set IP addresses of your smartphone and CIE-H14 to the same range.

ex) Smartphone’s IP address :, Netmask : / CIE-H14′s IP address :, Netmask :

Then you can start testing your mobile and CIE-H14. The cieManager is sufficient for simple test for CIE-H12 and CIE-H14.

We hope them to release one for CIE-H10 soon.
