MOXA I/O Devices
Application of MOXA I/O Modules
I/O modules are used to connect various sensors, counters and other terminal devices to control and monitoring systems. Moxa has a fairly extensive line of I/O devices.
Differences between IOLOGIK E1200, E2200, 2500 and IOTHINX 4510 series
Selecting IOLOGIK E1200 Device
If you only need to collect data from end devices and transfer them to the upper level, then you should pay attention to the ioLogic E1200 line.
Selecting the IOLOGIK E2200 Device
If you need to not only collect data, but also perform simple programming, then you should choose equipment from the ioLogic E2200 line with the ability to create logical rules IF-THEN-ELSE.
Selecting your IOTHINX 4510 Device
The ioThinx modular system is perfect for organizing interaction between ICS and IT systems. The ioThinx 4510 supports up to 32 expansion modules with digital and analog I/O channels, as well as support for both ICS and IT protocols.
ioThinx 4500 Calculator will help you assemble a modular ioThinx 4500 system with the necessary I/O channels and additional power modules.

Click and Go Rules
Logical Click & Go rules are IF-THEN-ELSE rules. Serve for programming I/O modules for simple tasks. This functionality is supported only by devices of the series ioLogic E2200 and ioLogic 2500(Click & Go Plus).
• Click & Go are configured in the ioAdmin utility, the maximum number of rules is 24.
• Click & Go Plus are configured in the IOxpress utility, the maximum number of rules is 48.
Peer to Peer
The Peer-to-peer function (pairing) allows transparent extension of digital and analog signals over Ethernet networks. The state of the input channel of one module will be translated to the output channel of the remote module.
Polling MOXA I/O Devices using RESTFUL API
Some Moxa I/O devices support the RESTful API protocol for ease of integration into web services and network applications.
ioLogik E2200 DIO Channel Settings
In ioLogik E2200 modules, the type of each channel is configured programmatically in the ioAdmin utility.
First you need to select the channel type DI or DO, save the settings and reboot the device. Only after that it will be possible to determine the parameters of the channels.
ioLogik E1200 DIO Channel Settings
In ioLogik E1200 modules, the type of channels is determined by hardware. Channels can be set to different modes of operation.
To do this, remove the device cover (unscrew the screw at the back, pull out the terminals and remove the module cover) and set the jumpers to the desired mode.
The default mode is DO.
In addition, jumpers can be used to set the parameters of the analog input channel.
Ethernet/IP Protocol Activation for ioLogik E1200 Series
ioLogik E1200 devices optionally support Ethernet/IP. In order for this feature to appear, you need to update the ioLogik E1200 firmware to the latest version and go through the activation procedure. Step-by-step activation instructions are available.
Why is RS-485 on the E2200?
The ioLogik E2200 series modules have an RS-485 serial port. It is intended only for connecting ioLogik R2200 devices, which will allow you to increase the number of I / O channels. In this case, the E2200 module itself cannot be polled using the Modbus RTU protocol.
MECHANISM OF ACTIVE INPUT/OUTPUT
To collect data from end devices, it is necessary to periodically poll the status of channels, but this is not always efficient and fast, especially if data collection modules are used in critical systems. Moxa introduces Active IO technology, which allows you to reduce the data update rate in multiple data. This is due to the fact that the ioLogik modules themselves send channel parameters when their state changes.
The data is sent to the OPC server, which in turn interacts with the SCADA system. Moxa has developed its own OPC server – MX-AOPC UA Server.
How to set up active I/O
In order for the ioLogik modules to actively send data to the OPC Server, you need to perform simple settings. You can configure the device through the web interface or the ioSearch utility in the AOPC Server Settings section.
